What are Western Disturbances | How does it impact rain and snowfall in India

- The only source of rainfall and snowfall in the hills of North India are extratropical storms known as western disturbances (WDs). These form in the Mediterranean region and travel eastward to northern Bangladesh and south-eastern Nepal. It is a non-monsoonal precipitation pattern that induces low pressure systems in the lower layers of the atmosphere. This, ultimately, causes rainfall in the plains and snowfall in the mountains.
The WDs have been showing a declining trend in intensity in the past few years due to changing climate.
While Uttarakhand experienced 47 percent less rains than normal from October 1 to December 27, the deficit in Himachal Pradesh was 40 percent, according to data from the IMD. Media reports say that snowfall has reduced drastically in the mountains of Jammu and Kashmir even though there has been rainfall during the post-monsoon season.
The lack of snowfall in the mountains affects the yield of Rabi crops in some regions and availability of water in the mountains in general. The majority of Rabi crops are sown there in October and November, so rains during these months are extremely important.
More than 80 percent of Himachal Pradesh’s agricultural land is rainfed.
Only four years between 2004 and 2023 saw normal or above-normal rainfall in October (IMD).
Experts have attributed the continuous decrease in rainfall in the post-monsoon season for the last few years to climate change.
SP Bhardwaj, a horticulturist (former joint director at Dr YS Parmar University of Horticulture and Forestry in Nauni, Solan,) told DTE that the fruit trees are stressed due to the prolonged dry spell. “Apple production will suffer greatly as a result of the prolonged drought and lack of snow. The dry spell has also caused problems for horticultural farmers who were planning to plant new orchards,”
“The western disturbance activity witnessed a southward dip in December, causing good rainfall over central India, but either deficient or scanty rainfall over most of northern India in December”, Akshay Deoras, a research scientist at the National Centre for Atmospheric Science and Department of Meteorology, University of Reading, United Kingdom, told Down To Earth.
Towards the end of November a moderately intense WD interacted with an extended low pressure area embedded within the winds blowing from the east over central India and caused significant rainfall in central and western Indian states of Gujarat, Maharashtra and Rajasthan. States of southern India such as Telangana and Karnataka also experienced deficit rainfall in the post monsoon season (October to December).
Apart from this, the El nino phenomenon causes India’s monsoon rains to plummet as well. El Niño is a climate pattern that describes the unusual warming of surface waters in the central and eastern equatorial Pacific Ocean. This happens every 2-7 years. The changes in the temperature of the ocean surface affect the trade winds in the atmosphere causing heightened temperatures and lack of rainfall in many regions. India's monsoon rainfall for the year 2023 hit a five-year low, marking the lowest since 2018 due to El Nino.
In Kashmir, El Nino's impact is evident through prolonged dry spells, milder winters, and diminished snowfall. Experts caution that the region is likely to face more frequent and extended dry periods in the future.

Very sorry to hear of this change in weather patterns in Northern India and I wish you all the best. Unfortunately the worldwide use of fossil fuels continues to escalate.
It's not just the snowfall, the temperature has risen, and it was unlikely to see a warm sun in winter until now.
It is happening all over Himalayan state including our state Uttarakhand also the day temperature is 4 to 6 degress above normal but the night temperatures are +-3 degrees.
Save hasdeo forest if you want kashmir to be evergreen 🌲
What is going on in these forests?
U mean Hasdeo bango ??
@@jashanmittalpediatriciandr9596 they are cutting thousand of trees to build coal mines.....
@@jashanmittalpediatriciandr9596being cut down by govt. for mining etc. Adivasis are trying to save it but people on SM are making it a political & religious issue rather helping them. We humans are the worst thing that has happened to planet earth.
I've talked to a know there they said they are uneducated people cutting tress and selling In lack of unemployment
If someone try to stop they threatened them with their axes and sickles
Govt. Of chhattisgarh newly formed BJP govt. Should do something about this
People should be given knowledge about environmental changes should teach them why tress are important
Same here in pakistan. I was thinking the same. This year saw no rain or snow. It's really concerning
Same in Upper Himachal
Getting dusty 😢
Himalayan God is angry
@@VijayThakurMD Yes very dusty also in Pithoragarh Uttarakhand.Landscape looks like desert and day and night temperatures are very distinct.Like maximum temperature of 20/01/2023 was 12.7 degrees and minimum was -5.3.
18 degree difference.
Good coverage but I should add that the subtitles in local languages as well would help the outreach of the channel massively. It aso can be done easily using AI.
There was no snow in Ladakh, my hometown, it's never been this warm in winters. we are dreading the summers 😢
Jammu is more cold than kashmir this time😢🥶
Also, Jammu is colder this time around due to excess pollution
If this is the way weather will keep changing, it won’t be long that water is going to be very scarce. Time to wake up and take all precautions possible to prevent global warming
Mafias of plastics, industry, banks, fertilizers blah blah you have to face all those
Seem inevitable
This little spanish boy el nino is taking down our old chilla e kallaan
We will have to adapt to this change in the weather patterns. Farming/food security, water security, tourism and healthcare will become dependent on this.
Sad.... even for rain we are dependent on West 😭😭😭😭😭😭
Bruh
😢😢
It’s el nino, this and the next year are the ones. Also the polar vortexes are upwards this year
In Assam summar tempt was 32 degree now almost 40 winter was 2degree now 10 degree same issue in shillong . 25 years ago we don't need fan in shillong now we need ac 😂 in shillong ..n our pm say climate change nhi hua ham change huye
I'm 2013-14, average maximum temperature in June July in patiala (Punjab) was 36-38 degrees now 43-45 is normal in summers. This is becoming more and more pathetic along with disturbing rainfall patterns and intensities.
Plzz provide the link where pm said this
Well u can't expect other than that from an illiterate pm 😂
@@SarojSingh-nq5ql no requirement of it , as you will still not believe it as you are wearing the bhakt chashma
@@gurjotsingh8934patiala current temperature down bad😢
Im from j&k.
It feels like it's june july here 😢😢
I wonder what June July will feel like 🌡️
👍🏻👍🏻
Bass krr Bhai....JMU Mai boht thand hai
@@adaa4506 haan jmu mai bht thand hai
Becoz winter climate of jammu division depends on winter climate of Kashmir division, they go inversely with one another.
It's hot here in kashmir division so it has to be cold in Jammu division
(Me district anantnag).
Last week kashmir division has surpassed jammu division in terms of hotness in winter season.
Yesterday it was 8° in Jammu and 13° in kashmir division

Is saal uttarakhand m bhi snowfall nahi hua
Kahi nahi hua hai. Kashmir s Uttarakhand tak.
with the lazy Indian state governments who are entirely profit oriented, I am glad there were no western disturbances here in the North this year. I have to bike to my medical college for around 1 hour in 3-4 degrees Celsius against dense fog which is already bad enough to have me entirely wet. What would it hurt if we had something as basic as winter vacations in our colleges? I already have a cough for 1 month. Everyday when I reach the college it feels like I am about to die, either from an accident or AHF.
I can't believe that winter has not arrived yet in my town due to no rainfall😶
Construction of hydro electric projects and changing the natural flow of rivers is also making climate change.
I m from allahabad or prayagraj, it was like mussorie yesterday fog started covering from 7:00 pm onwards yet there was no fog in commercial area
We are literally watching climate change here in my village in jammu region not a single drop of rain in whole winter
I'm from Jammu, J&K; a plain city in the foothills of lower himalayas.... this year it was more colder than Kashmir vallley in the Day... temperature didn't go above 10 degrees for a week without seeing Sun... whereas in Srinagar it went 12-13 degrees.. which means Jammu was more colder than Srinagar in the day....
Uttarakhand k mussurie me 2021 se snow hi nhi padi...climate change
Well, not everything is western disturbance but a consequence of rapid unplanned urbanisation, forest cutting and building dams at high altitude.
Industry hazards the major reason
Exactly. We are equally to blame for blatant "development" with no respect for Mother Nature. Hopefully, our government is equally concerned about this.
Now Himalayas are destroyed boy human greed.
Same problem in Pakistan. This year it almost destroyed orange crop of central punjab. Which is biggest export of central punjab
❤
Really scared abt the days to come
Our Apple, Apricot produce will die without snowfall, if it doesn't happen anytime soon!
Western disturbances not only impacts climate of India but also political stability in India Lol
does the solar maximum play the part in this climate change as it's in high peak till 2025?
The worst is yet to come
Gov please dont destory forest
..
Bhai tu north east se hai n?
Literally u people cry in every comment section ki humare yaha air Port, railway, roads, gift city, Noida, gurgaon jese project q nahi laate and the moment gov approve some project u people cry for environment.
Nahi gov aasman Mai banaye ye sab.
Yaa to tum log hi alternative bata do.
Ye do muhi baat to mat kya karo.
@@SarojSingh-nq5ql from northeast..
Yes some of them are rascals they want everything without any sacrifice which is a joke
This is due to el Nino
It may be due to bombardment between Israel -Gaza & Russia and Ukraine because they caused a lot of air pollution. Israel used phosphorus and other weapons which were banned still they fired on innocent Gaza people..The pollution created due to this bombardment was 5 times more than the Hiro Shima Nagasaki bomb.
I think this may be the main reason for the change in climate all over the world especially in Jammu & Kashmir
learn about super el nino. wars like these put no toll on global climate
and people laugh at whenever climate protesting held at anywhere
only impact ,no explanation on why and how are these created.
Western disturbances comes from Mediterranean sea. Mediterranean sea this time full of blood in Israil Palestinian war. Thus no rain and snow
nothing to do with that.just the cyclic super El nino current this year.
IMD is India meteorological department....not indian
Define climate change
About time humans pay for their sins
As a producer of Green Fuels here in India let me just say ….BAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAAAAA
Save hasdeo & bakshwa forest.....❤
