The atmospheric lapse rate is the change in temperature with height. For example, on average the temperature cools 6.5 C for every kilometer. Of course, this varies from location to location. We can use observations to determine the lapse rate of a particular location. The observations are gathered from a miniature weather-monitoring station (smaller than a shoe box) that is attached to a balloon and released into the air twice a day at various sites throughout the world (a radiosonde). The value of the lapse rate is strongly dependent on the amount of water vapor in the air. Dry air cools at about 10 C/km (the 'dry adiabatic lapse rate'), while moist air usually cools at less than 6 C/km ('moist adiabatic lapse rate'). The word adiabatic means that no outside heat is involved in the warming or cooling of the air parcels. Why are the two lapse rates different? Remember that water vapor in a rising parcel of air will condense when the air becomes cold enough. The phase change from gas to liquid takes a little work from the water molecules. As they are working, they release heat. The heat decreases the cooling that occurs in the air parcel. Therefore, a rising parcel of dry air cools faster than a moist parcel of air. And conversely, a sinking parcel of dry air warms faster than a sinking parcel of moist air.
latent heat:when one phase changes to another phase like solid to liquid or liquid to vapour, it needs surrounding enery to convert its phase that energry will come through latent heat
This year apsc asked one question on albedo, and I remembered your video, and thanks just because of this video I was about to pick up the correct answer 😁😁😁
When moist air packet rises it becomes cool and gives latent heat of evaporation, then how does it gain heat again??? This is confusing. Please clarify
Air also has water vapour.As both rises above(heated surface of earth),water vapour starts condensing releasing heat.This heat further warms air,and it rises further until even air starts cooling and they both together brings rainfall.
I think you are saying wrong dude ... air is moist and it will need energy to rise up i.e to change into vapour so ma'am is correct because it is latent heat of vapourisation ... please correct me if im wrong
@@Kishan4393316 As air(water vapour) ascend, its temperature decreases. This decrease of temperature results in change of some water vapour to water droplets(i.e. from gaseous state to liquid state or condensation). And change in state from gas to liquid causes release of latent heat which is called latent heat of condensation. Hope this helps!
she is right here.. Absolute stablility is when NLR DALR, the air parcel's temperature is more than surrounding temperature as it doesn't cool fast, so it's tendency is to go up
Absolute instability should happen if normal ALR < wet ALR < Dry ALR right ? Because when lapse rate is less then instability is more(air reach greater heights). Pls correct me if I m wrong.
There is latent heat of evaporation or condensation Bcoz in latent heat of condensation the heat is released but in latent heat of evaporation heat is absorbed..... Can somebody explains
In the earlier video, while explaining instability, she said that warm air being lighter initially rises, its moisture evaporates, its temperature increases and it rises higher, than condensation happens and cloud formation takes place and temperature decreases. But in this ppt @ 14:28 temp is shown only to increase. Why ? Can anyone explain?
Did you even know what is condensation it is an change of vapour or gas to liquid so how it come to helps in releasing heat ?? She is talking about latent heat of condensation !
@@shivanichoudhary9250 yes she is talking about latent heat of condensation but mistakenly she said evaporation ...even in the diagram condensation is mentioned ....
@@shivanichoudhary9250 warm air rises, releases latent heat of vapourization to surrounding, this surrounding hot air further goes up and then releases Latent heat of condensation.
Adiabatic lapse rate nahi hai woh.....normal lapse rate hai 6.5°C/Km........ adiabatic are of two type: Dry adiabatic lapse rate= 10°C/Km Moist (saturation) adiabatic lapse rate= 5°C/Km Normal lapse rate and adiabatic lapse rate dono different phenomena hai....
Conditional Stability: This occurs when the WALR is less than the NLR, which is less than the DALR (WALR < NLR < DALR). This means that an air parcel needs to be lifted to its condensation level (lifting condensation level) to become unstable and rise further. An air parcel will continue to rise as long as it is less dense than the surrounding air. When the ELR is greater than the WALR, it means the air temperature is decreasing faster with height in the environment than the rising air parcel is cooling. This creates a situation where the rising air parcel becomes warmer and less dense relative to its surroundings. This lower density provides the necessary buoyancy for the air parcel to continue rising Absolute Stability: This occurs when the NLR is less than both the WALR and DALR (NLR < WALR < DALR). In this case, a rising air parcel becomes colder and denser than its surroundings, causing it to sink back to its original position. Absolute Stability: This occurs when the NLR is less than both the WALR and DALR (NLR < WALR < DALR). In this case, a rising air parcel becomes colder and denser than its surroundings, causing it to sink back to its original position. Absolute Instability: This occurs when the WALR and DALR are both less than the NLR (WALR < DALR < NLR). Any air parcel lifted will continue to rise due to its warmer and less dense nature.
Remember alwys tht cold air is denser than warm.air in lower altitudes onlyy because they pack too much molecules with them but as we go to the higher altitudes cool air is less denser than warm.air...
It may be because of the fact that supply of the heavier gases and aerosols are found in the lower layers near the earth surface while lighter gases like hydrogen reaches the limit also its concentration is more because of nearness to the earth due to earth's gravitational force may be
Absolute stablility is when NLR DALR, the air parcel's temperature is more than surrounding temperature as it doesn't cool fast which results in it having more temperature. So it's tendency is to go up creating instability Conditional instability: WALR
You said incoming of solar rays does not absorbs by atmospheric layer as they being short wave radiation then how did it came that 35% of heat absorb by ozone before reaching to the earths surface ??

Latent heat of condensation is released as water vapour condenses
And it heats the air.

@16:37 i think conditions of Absolute Stability and Absolute Instability are Reverse, Correct me if i am wrong
Even i think so
she is right here..
Absolute stablility is when NLR DALR, the air parcel's temperature is more than surrounding temperature as it doesn't cool fast, so it's tendency is to go up
34% reflected by atmosphere, 14% absorbed by atmosphere, 51% enters in earth and get radiated.

Mam.. As we knw that low temp.. Means air molecules are tightly packed hence high pressure... Then why at higher altitude there is low pressure
Sarita Bhadoria because of earth rotation.
Cool air is more dense as compared to warm air-as height increases temperature decreases.so how can air be less dense at high altitudes
Remember alwys tht cold air is denser than warm.air in lower altitudes onlyy because they pack too much molecules with them but as we go to the higher altitudes cool air is less denser than warm.air...
It may be because of the fact that supply of the heavier gases and aerosols are found in the lower layers near the earth surface while lighter gases like hydrogen reaches the limit also its concentration is more because of nearness to the earth due to earth's gravitational force may be
You should factor in atmospheric pressure while thinking about density
