One of the interesting questions I've tried to answer is the location of the highest latitude locations which have never frozen (in both hemispheres). For the northern, I'm almost certain that the answer is either Menton (the Wikipedia climate data shows it just barely has but I strongly suspect that the most protected and coastal microclimates have not, due to some circumstantial evidence of well established equatorial plants growing in the gardens there) and if not that then _definitely_ the Azores which haven't even gotten close even for the northernmost ones. For the southern, this is a lot harder, Mallacoota is the best candidate I've found yet that for sure never freezes, but I strongly suspect the more protected parts of the Corner Inlet and/or some islands present in the inlet do not freeze either (once again the data for a few locations here shows they just baaarely froze but these are along some more exposed sites). Cape Grim and King Island are other good candidates. Amazingly, the subpolar Auckland Islands have shockingly mild record minimum temps, and even support a population of tree ferns at a whopping 50 degrees south. Perhaps some ultra protected inlet could have never recorded a freeze? Either way, the temperate areas that _don't_ freeze are just as interesting as the tropical ones that do. Another fun one is coastal Norway, which while it definitely does freeze also has ridiculously mild winter temps, Tromsø has a higher record min temperature than Tallahassee and some places in the Lofoten archipelago like Vågan and Røst barely ever even graze past -10 C despite being above the arctic circle. edit: Ile Amsterdam in the Indian Ocean is another good candidate, roughly the same latitude as Mallacoota and has never frozen. Its also interesting because the temperature range is ridiculously small on it, under 25 C between the _record_ min and max temps, probably the most oceanic climate on Earth. Additionally, its quite nearby to Kerguelen, an archipelago which basically acts as a mini Antarctica but at an unusually low latitude, complete with a tidewater glacier, barren rocks, and a tundra climate. edit 2: Bruny Island in Tasmania looks like another really good candidate, once again barely ever froze and is very far south.
@@alunjones3860 A lot of these temp records go pretty far back into the 20th century or even before, but yes this does make it more difficult. Of course if you go far back enough you end up at the last glacial maximum where of course these places would freeze, or even back to the little ice age where if they are borderline never freeze climates they might have frozen then too. So there needs to be some sort of reasonable limit on the timescale, some people might set this at different times but I'd imagine as long as its long enough to capture at least a handful of serious, record breaking cold waves its reliable enough for me. Definitely worth going for the climates that haven't even remotely frozen though if you really want to hedge your bets and/or capture a longer timescale with more global variation, but this doesn't really matter if you're just looking for a place you can grow cool plants and experience comfy winters at a high latitude.
In Brazil we had an interesting event in 2022, where a strong cold wave in May reached lower latitudes. Brasília, in the deep interior of the Brazilian Cerrado, a savanna climate, reached really close to freezing point. And also in Brasília theres a record of frost in 1964

As a farmer it’s funny to see all the images of fruit being covered in thick ice. This is a technique used to PREVENT fruit from freezing, you just run the overhead sprinklers until you build up a layer of ice which insulates the fruit and actually helps trap some heat in it and it prevents cold wind damage as well. It’s used most on citrus but even strawberries respond well to it.
Yep, it's a reliable technique in Florida. In drier areas you have to be careful about the humidity, though--or it can have the opposite effect. Using sprinklers in extremely dry air can cause evaporative cooling, creating more frost damage.
8:29 I'm from Tampico, we had hail as recently as 2016. Also, sometimes winters get so cold (between 10 to 5ºc) that the iguanas in our parks get "frozen" and fall from the trees.
Originally from Hidalgo and we get hail in summer, i always associated with summer not cold weather. In Tamaulipas Tampico is not exception, Matamoros and Nuevo Laredo get below freezing temps some winters, but they are not tropical.
A particularly fascinating case in my opinion is eastern Australia. Mackay has recorded a freeze (just barely), while Mallacoota has not, despite Mackay being a borderline tropical climate and Mallacoota being solidly temperate, and the latter being a whopping 16 degrees of latitude further south. Both are along the eastern coastline, at sea level. The hardiness map of Australia is exceedingly weird, lots of little pockets of, well... not quite _micro_ climates, but definitely weird local variations dotted all over the place.
I enjoy this type of content. Thanks for sharing! I have always assumed that tropical areas that freeze, are considered subtropical, like where I am in Northern FL. I have found that some of the traditional Southern plants are extremely cold hardy, like the Southern Magnolia, Sable Palm and Live Oak for example. They can handle subzero (subzero F) temps in many cases.
Very true, those species (and reptiles like the American Alligator) evolved to capitalize on high average temps, but to also survive surprisingly cold extremes.
Tropical climates can freeze it's just very rare. I think much of Brazil has seen a freeze at some point save the Amazon and the northern coastal areas. Subtropical climates see overnight freezes on a regular basis in the winter time.
Its also something you have to be _very_ wary about when researching for zone pushing, since the same climate zone in the east coast is very much so not equivalent to that of the west. Northern Florida is technically in the same hardiness zone as much of Washington state, but the cold events there tend to be brief and followed by warmer weather which is much easier for plants to get through than the days to weeks of minimum temps you get on the west coast. Plants that can easily handle east coast 7a often struggle even in 8b winters in the west, so east coast growers' reports of cold hardiness often don't work out west.
@@StuffandThings_ Average temperatures are essential to consider, yes. Not just in terms of plants surviving, but also growing, reproducing, and competing with other vegetation. Being able to stick an adult palm in the ground in Vancouver is interesting, but not very meaningful outside a landscaping context.
There are tropical forests that can suffer eventual frost and even SNOW here in Salta and Jujuy, Argentina! Baritu National Park is an example... Nevertheless, these zones do present more regular snowfall so plantlife (even epiphytes) are more adapted to these events.

1:40 The alps play a big role in regulating the climate of northern Italy (the Po Valley). Compared to the oceanic and humid continental climates on the other side of the alps, in northern Italy we have less warm winter warm spells caused by mild Atlantic currents, because of temperature inversion (Venice can have 1°C/3°C days with fog while Stuttgart in Germany has 6°C/10°C days), but also much less cold winter cold spells, with relatively dry -3°C/+3°C while Stuttgart experiences -7°C/-3°C extremes or colder. I would love it if you made a video about the climate of the Po valley, I think you could draw some climatic parallels with the US Midwest even if our climate is a lot less extreme (Milan has similar avg annual temperature to Kansas City, with warmer winters, colder summers, and a storm season in summer which can cause violent storms and hail but rarely tornadoes, contrary to the Midwest)
This would be a great topic! He could also include an explanation as to why Istria, at the same latitude of the Po valley, has a typical Mediterranean landscape, while the same vegetarian only grows along the subalpine lakes on the west side of the Adriatic
@@Forlfir yes, being on a plain enclosed in mountain ranges on three out of four sides in a very densely populated and industrialized area, with only the very shallow Adriatic Sea on the other side does make for relatively static conditions and a lot of pollution
@@Forlfir another major difference with the Midwest is hours of sunlight. The Midwest is a lot sunnier than northern Italy. We’re talking 1900-2100 hours of sunshine per year for the Po valley, and 2700-3000 for the Midwest, despite similar annual rainfall.

It's funny, I was just reading about phenomena like this! I've always been fascinated by tropical plants, as I live in a temperate region. So, I read a lot about tropical plants that can survive cold weather.

I’ve always found Tamaulipas to be so fascinating due to its botany. You can find many species of epiphytic orchids at their northern limits despite the risk of frost. Reserva Biosfera El Cielo is a lush tropical forest that is the northernmost tropical forest in the Americas.
While the extremes and frequency can not match those in the Americas, especially North America, north eastern Australia can occasionally get random freezing spells north of the Tropic of Cancer. I suppose the great dividing range also drives this, but given the milder climate of Australia generally and the low height of those mountains, can not generate the same effect as the Americas.
Also the Southern Ocean between Antarctica and Australia moderates polar blasts far more than the landmasses of Asia and North America which stretch all the way from tropics to the Arctic. Also, cold temps in northern Australia only happen at night. In daytime, it still warms up to around 20C during those cold snaps, with a big contributor being very low humidity in northern Australia during winter allowing for large diurnal range. Areas around Tropic of Cancer in North America and Asia actually have winter days where it stays cold all day
Finding unexpected climates is a topic that has always fascinated me. Therefore, I cannot help but mention that the coldest and most tropical country at the same time must be Peru. Its southernmost point is at latitude 18°S (which would correspond to Jamaica in the north). Even so, 70% of all tropical glaciers in the world are in Peru, precisely because of the combination of the high altitude of the Andes and the humidity coming from Ecuador. Bolivia, for example, being a little further south has also the altitude and a geography within the tropics, but very few glaciers since the areas close to the limits of the tropics have less humidity. Another reason for Peru is to find frozen areas at sea level due to the Humboldt Current which is the coldest in the world (not the coldest in absolute value, but in comparison with the temperature of the Pacific at those latitudes). The Peruvian coasts are usually 10 degrees colder than the ocean waters, this causes hail to occur at only 100-200 AMSL and near the sea at a latitude as "warm" as 12°S (it happened in Lima in 2021) or temperatures that can reach 0.6°C near the sea which is the coldest reported in the coastal plain. It would be interesting to expand on the topic of the very strange and cloudy climate that the coasts of Peru and Angola have due to their cold currents.
I lived in Palm Beach County Florida in the 1970s and 1980s. The Freeze Line runs just South of Lake Okeechobee across the State. In January 1971, we had a record low of 28 degrees. All the citrus groves had their sprinklers running and there were ice cycles hanging from the trees. I remember the snow in 1977, we were in class when the snow started. We were in disbelief watching it fall. We matched the 28 degrees December of 1989. In that year, the cold lasted a few days longer than the one in 1971 and killed off the leaves on most of the trees.
Many plant species have adapted to survive these cold fronts. In Tamaulipas there is a tropical plant/palm that is called chamedorea radicallis and it can take snow. I grow it in Texas and New Mexico and it thrives even in harsh winters. There are many other plants that have not been discovered yet or tested for cold hardiness.
This is such a fascinating topic, I learned so much from this video! Another case of tropical flora surviving occasional cold snaps that i've always found interesting is Spanish Moss (a bromeliad) in the southern US. It's northern limit seems to be coastal Virginia, but still, very impressive for a tropical epiphyte. I'm so glad I found your channel, can't wait to binge the rest of your videos!
I remember snowfall over the Great Pyramids of Egypt is a popular image for disaster movies and science fiction. I wonder if it's actually happened, though.
In 2013, the same weather phenomenon I mentioned in the video did cause heavy snow in the mountains of Sinai and the highlands of Jordan, with some reports of a tiny bit of non-accumulating snow in northern Egypt. Not too surprising for Sinai though--St. Catherine's Monastery is >5,000'/1500 m.
I live just on the Tropic of Capricorn in Central Queensland. This winter it got down to freezing twice. Interesting you mentioned lizards. I used to live in the Cootamundra area in NSW where the temperature gets down to -7 sometimes. There is a large lizard called the Perentie that seems to live quite well there. Maybe it has adapted to the cold. You would expect to see them live in the tropics rather than a cold climate, although we used to have heaps of snakes in the summer, so similar, I guess.
There is another species of large lizard in the same genus as the Perentie, the Desert Monitor, which endures very cold winters in Central Asia (specifically the subspecies "Caspian Monitor"). Those ones brumate during winter. But I am sure there are other adaptations these animals have which are not written about.
This is a topic I have a personal interest in, particularly during the last glacial maximum. Planning on doing a blog about it for the earth science blog I’m launching soon.
One of those rare southern snowfall near the geographical limit explained in the video was the cause of the downfall of the coffee plantations/indutry in Cuetzalan acordign to the locals I met on one of my recent trips there :( When I learend that they have seen snow it blew my mind and was the recent I clicked on the video... I wanted to know how a place thats warmer and "lower" than my 2000+m in altitude city has seen snow with far more regularity than my typical high altitude Mexican city xD
I came in this video already knowing Florida would be in it. It was 75 outside today, which is basically freezing for mid September. This is especially crazy when you consider the Gulf of Mexico is the world's largest jacuzzi
You can research about the great cold wave of July 1975 in South America, to this day one of the coldests "friagens" to reach Central and Northern Brazil, with frosts being recorded in areas within the Amazon. Also, an unique phenomenon that occurs only in South America is that a cold front can reach the Northern Hemisphere through the Amazon, as it has happened before many times with the cold reaching as north as 10˚N in Venezuela.
The Challenger Disaster happened because it was so cold in Florida and many execs and the president were impatient to launch. Icicles formed on the rocket, and the o rings which are supposed to be flexible, froze and became very rigid, allowing a gap from the rocket boosters through which burning fuel was being released, eventually damaging the rocket through a snowball effect until the superstructure failed.

I’m not sure if this is a tropical region but Dar Es Salaam in Tanzania on Africa’s east coast has been known to get snowfall which I think is interesting. A lot of east africas major cities have actually been know to receive snowfall but this is due to the higher elevations of places like Addis Ababa, Nairobi, and Arusha. However Dar Es Salaam lies at sea level which I think is interesting.
While it is not freezing air, sometimes the Friagem will cross the equator into the north hemisphere bringing significant below average temperatures to the heart of the amazon

You can do the opposite, places at latitudes that should see snow but don't , like Portugal in mainland Europe snow at latitudes lower than Lisbon like Athenes Greece got more snow days than Lisbon

I've always wondered if this kind of weather patterns happens in those "cloud rainforests" or those high altitude rainforest regions. I think there is also sky islands in Africa at the top of those flat topped mountains.
Many cloud forests are surprisingly frost-free despite their cool average temps, depending on elevation. However, the cloud forests on the edges of the cold air damming regions I mentioned in this video are definitely vulnerable to frost.
Here in Indonesia, an archipelago nation right on equator (Indonesia lies between 7 degrees North-10 degrees South), in many towns in the highlands, freezing temperatures are a seasonal norm. Example: Dieng village (altitude: 2000 m) below Mt. Prau (2500 m) in Java, there are 1-2 weeks every year in the SUMMER where it goes 0, lowest record -10. But how come in Summer? coz ummer = dry season. In "winter"/monsoon, rain/humidity makes it warmer. You should try researching this more because this happens on islands, not continents like the examples

Have you taken into account how far back weather records go? Just because it hasn't been recorded, it doesn't mean it's never happened.
@@alunjones3860 A lot of these temp records go pretty far back into the 20th century or even before, but yes this does make it more difficult. Of course if you go far back enough you end up at the last glacial maximum where of course these places would freeze, or even back to the little ice age where if they are borderline never freeze climates they might have frozen then too. So there needs to be some sort of reasonable limit on the timescale, some people might set this at different times but I'd imagine as long as its long enough to capture at least a handful of serious, record breaking cold waves its reliable enough for me.

While the extremes and frequency can not match those in the Americas, especially North America, north eastern Australia can occasionally get random freezing spells north of the Tropic of Cancer.
I suppose the great dividing range also drives this, but given the milder climate of Australia generally and the low height of those mountains, can not generate the same effect as the Americas.
Also the Southern Ocean between Antarctica and Australia moderates polar blasts far more than the landmasses of Asia and North America which stretch all the way from tropics to the Arctic. Also, cold temps in northern Australia only happen at night. In daytime, it still warms up to around 20C during those cold snaps, with a big contributor being very low humidity in northern Australia during winter allowing for large diurnal range. Areas around Tropic of Cancer in North America and Asia actually have winter days where it stays cold all day

Finding unexpected climates is a topic that has always fascinated me. Therefore, I cannot help but mention that the coldest and most tropical country at the same time must be Peru. Its southernmost point is at latitude 18°S (which would correspond to Jamaica in the north). Even so, 70% of all tropical glaciers in the world are in Peru, precisely because of the combination of the high altitude of the Andes and the humidity coming from Ecuador. Bolivia, for example, being a little further south has also the altitude and a geography within the tropics, but very few glaciers since the areas close to the limits of the tropics have less humidity.
Another reason for Peru is to find frozen areas at sea level due to the Humboldt Current which is the coldest in the world (not the coldest in absolute value, but in comparison with the temperature of the Pacific at those latitudes). The Peruvian coasts are usually 10 degrees colder than the ocean waters, this causes hail to occur at only 100-200 AMSL and near the sea at a latitude as "warm" as 12°S (it happened in Lima in 2021) or temperatures that can reach 0.6°C near the sea which is the coldest reported in the coastal plain. It would be interesting to expand on the topic of the very strange and cloudy climate that the coasts of Peru and Angola have due to their cold currents.
I love that you prefer quality (or geologic oddity) over quantity
Best part of the channel!!
Fascinating video as always, lots of new information to me!
Very interesting topic. I never thought rainforests could get cold.
Mountains are the reason why the arctic air hits Denver and not Salt Lake City, the Rockys are a nice natural block
Arctic air does hit Salt Lake City
@@thomasgrabkowski8283 Not very often!
@@thomasgrabkowski8283rarely tho, esp. when compared to the other cities of the same latitude that are east of the Rockies.
@@thomasgrabkowski8283what is arctic air?
I lived in Palm Beach County Florida in the 1970s and 1980s. The Freeze Line runs just South of Lake Okeechobee across the State. In January 1971, we had a record low of 28 degrees. All the citrus groves had their sprinklers running and there were ice cycles hanging from the trees. I remember the snow in 1977, we were in class when the snow started. We were in disbelief watching it fall.
We matched the 28 degrees December of 1989. In that year, the cold lasted a few days longer than the one in 1971 and killed off the leaves on most of the trees.
Incredibly intriguing. I love learning new stuff about weather and geography I had not known of before!
Many plant species have adapted to survive these cold fronts. In Tamaulipas there is a tropical plant/palm that is called chamedorea radicallis and it can take snow. I grow it in Texas and New Mexico and it thrives even in harsh winters. There are many other plants that have not been discovered yet or tested for cold hardiness.
I literally love watching your videos man , i sometimes rewatch them
Excellent presentation. The speaker's voice is beautifully modulated.
This is such a fascinating topic, I learned so much from this video! Another case of tropical flora surviving occasional cold snaps that i've always found interesting is Spanish Moss (a bromeliad) in the southern US. It's northern limit seems to be coastal Virginia, but still, very impressive for a tropical epiphyte. I'm so glad I found your channel, can't wait to binge the rest of your videos!
I remember snowfall over the Great Pyramids of Egypt is a popular image for disaster movies and science fiction. I wonder if it's actually happened, though.
T R O P I C A L egypt isnt tropical
In 2013, the same weather phenomenon I mentioned in the video did cause heavy snow in the mountains of Sinai and the highlands of Jordan, with some reports of a tiny bit of non-accumulating snow in northern Egypt. Not too surprising for Sinai though--St. Catherine's Monastery is >5,000'/1500 m.
Great explanation of cold damming and east/west effects.
Great video!
As a weather and climate nerd, i LOVE this channel, thank you so much
Woooooh!!! Hometown of Brownsville mentioned!!
It was surreal to hear my city (Tampico) being called out as a geographic outlier
Fascinating as always! As a resident of a temperate clime this is all new to me and interesting
I live just on the Tropic of Capricorn in Central Queensland.
This winter it got down to freezing twice.
Interesting you mentioned lizards. I used to live in the Cootamundra area in NSW where the temperature gets down to -7 sometimes. There is a large lizard called the Perentie that seems to live quite well there. Maybe it has adapted to the cold. You would expect to see them live in the tropics rather than a cold climate, although we used to have heaps of snakes in the summer, so similar, I guess.
There is another species of large lizard in the same genus as the Perentie, the Desert Monitor, which endures very cold winters in Central Asia (specifically the subspecies "Caspian Monitor"). Those ones brumate during winter. But I am sure there are other adaptations these animals have which are not written about.
Might not be exactly tropical but the rainforests of appalachia are worthy of note
I love this channel!!
This is a topic I have a personal interest in, particularly during the last glacial maximum. Planning on doing a blog about it for the earth science blog I’m launching soon.
As always amazing content! There's nothing else like this on TH-cam.
This was the most interesting climate vid i have ever seen. Scratched all my itches.
underrated channel
Really cool video. Thanks
One of those rare southern snowfall near the geographical limit explained in the video was the cause of the downfall of the coffee plantations/indutry in Cuetzalan acordign to the locals I met on one of my recent trips there :(
When I learend that they have seen snow it blew my mind and was the recent I clicked on the video... I wanted to know how a place thats warmer and "lower" than my 2000+m in altitude city has seen snow with far more regularity than my typical high altitude Mexican city xD
All your stuff is so good man, we gotta get you the recognition you deserve
insanely good
I came in this video already knowing Florida would be in it. It was 75 outside today, which is basically freezing for mid September. This is especially crazy when you consider the Gulf of Mexico is the world's largest jacuzzi
You can research about the great cold wave of July 1975 in South America, to this day one of the coldests "friagens" to reach Central and Northern Brazil, with frosts being recorded in areas within the Amazon. Also, an unique phenomenon that occurs only in South America is that a cold front can reach the Northern Hemisphere through the Amazon, as it has happened before many times with the cold reaching as north as 10˚N in Venezuela.
You don't say! I though that Fishingarrett keeps the invasive pythons away from Florida! Dang, my life has been a lie 🤣🤣🤣
Lima is a coastal city located 12 degrees south of the equator, with a low altitude, yet it has a surprisingly cold climate. It blows my mind.
The Challenger Disaster happened because it was so cold in Florida and many execs and the president were impatient to launch. Icicles formed on the rocket, and the o rings which are supposed to be flexible, froze and became very rigid, allowing a gap from the rocket boosters through which burning fuel was being released, eventually damaging the rocket through a snowball effect until the superstructure failed.
Even in Indonesia, a country in equator line, still have below freezing temperature in some area
And mountain peak with snowtop
I wished we have place with lots natural ice, even seasonal, in the Philippines. However the country is surrounding by so much warm water. So much humidity. 😣
Thank you
Wait until TH-cam comes in and shoehorns the climate change context tab bcz this video talks about climate
I've seen them do that on videos not even discussing the climate, just ones talking about weather in a general sense.
@@planescaped Yeah, KnowledgeHusk's video on Earth's past supercontinents had that tab, and videos talking about the asteroid that killed the dinosaurs
Considering there's still idiots who refute this literally humankind changing phenomenon, I don't blame youtube for annoying us with this info.
I love seeing snow on palm trees ❤ Victoria Canada never disappoints
I love your videos so much.
I never thought of trees as reverse-shading the ground from space before.
Help, I’m falling into the sky!!! 😂😂😂😂 kidding lol
learned so much, great video!
On a small Caribbean island in the 80s🏖, there was one helluva cold day that I remember in high school.
We were shivering with chattering teeth under the midday tropical sun. 🌡
Our geography teacher said a North American front was sweeping the Caribbean.🌬
That day was CHILLY as FCK!🧊❄
Very good and interesting video! 👍🏼 Can you do a video about the micro climates of the Dominican Republic?
Guangzhou residents love to joke abt how they experience all 4 seasons within 1 week. Ya might hang out in tank top Monday but gotta put on a winter coat by Wednesday.
thank you for this wonderful lesson.
Excellent presentation! You have 1 more English subscriber.
Yes. My deepest curiosities have been satisfied. I shan't need to feed again for another few months 😂
Excellent content!!!+
Your videos are fun. Thanks CE
High mountain desert of southern California, north of Barstow.
Scorching hot all day, below freezing by dawn.
You can hear rocks splitting from thermal shock!
the mojave is not tropical.
Can you make a video about the flora and fauna of tropical montane regions that experience freezing and subfreezing temperatures? I would like to hear about how life has adapted to the higher elevations
Yeap ... quite interesting as it cover many consequences and adaptations due to this 'odd' geography and associated weather (subscribing)
Fucking Donkey Kong Tropical Freeze 🥶
My first thought was Guatemala and I was happy to see it included, even if it doesn't really count.
wow this is perfect for me
That was incredibly interesting
I’m not sure if this is a tropical region but Dar Es Salaam in Tanzania on Africa’s east coast has been known to get snowfall which I think is interesting. A lot of east africas major cities have actually been know to receive snowfall but this is due to the higher elevations of places like Addis Ababa, Nairobi, and Arusha. However Dar Es Salaam lies at sea level which I think is interesting.
Not often I see my hometown in a video.
While it is not freezing air, sometimes the Friagem will cross the equator into the north hemisphere bringing significant below average temperatures to the heart of the amazon
very interesting. excellent anecdote about the coral being killed in florida. i didnt know coral could serve as an indicator of short term drops in temperature, and i had no idea the freezes of the 70's and 80's in florida were unprecedented enough to serve as a serious selection event
He has returned.
Do more climate videos about cold weather pls
Thanks 4 a new vid
A climate that’s hot and humid and it can freeze? Someone put a military base there RIGHT NOW.
Your videos are really fascinating but please, when shifting subjects or after explaining a particular thing, take a breather. It allows us viewers to absorb what you hust communicated before you dive into the next point.
👍
You can do the opposite, places at latitudes that should see snow but don't , like Portugal in mainland Europe snow at latitudes lower than Lisbon like Athenes Greece got more snow days than Lisbon
Love the topic and I love him too
Even though you have an international audience if you are giving the temperatures in Texas you begin with Fahrenheit and then follow up Celsius.
The river Nile has frozen over twice at Cairo in the past two thousand years
Egypt is not Tropical
According to the Kopen climate New York City and long Island have a humid subtropical climate. UT used to be much colder. We used to have snow on the ground for a mibth. Now snow doesn't last long but a lot if tropical plants can grow here well into autumn. Before being taken insude. Autumn us the nicest season having temperatures in the 70s during the day and upper50 s at nught.
I've always wondered if this kind of weather patterns happens in those "cloud rainforests" or those high altitude rainforest regions. I think there is also sky islands in Africa at the top of those flat topped mountains.
Many cloud forests are surprisingly frost-free despite their cool average temps, depending on elevation. However, the cloud forests on the edges of the cold air damming regions I mentioned in this video are definitely vulnerable to frost.
there is always an exception to the rule
this man the goat
Here in Indonesia, an archipelago nation right on equator (Indonesia lies between 7 degrees North-10 degrees South), in many towns in the highlands, freezing temperatures are a seasonal norm. Example: Dieng village (altitude: 2000 m) below Mt. Prau (2500 m) in Java, there are 1-2 weeks every year in the SUMMER where it goes 0, lowest record -10. But how come in Summer? coz ummer = dry season. In "winter"/monsoon, rain/humidity makes it warmer. You should try researching this more because this happens on islands, not continents like the examples
I think you should read the title of the video....
diawal sudah dijelaskan bahwa dataran tinggi di daerah tropis bisa membeku itu contoh umum. jadi contoh Dieng itu tidak spesial.
No wonder the National weather service has freeze and hard freeze warnings on the ready for issuance
