1/N What is dry air and how it affects LPA or cyclone? Check this thread #Chennairains #Tamilnadurains #NEM2022 #Chennai #TamilNadu #94B

2/N Low pressure forms when air is warm from ocean surface(it can be from warm land as well)
When warm air rises low area of low pressure is created in ocean which attracts cool air as air moves from high pressure to low pressure area.#Chennairains #Tamilnadurains #NEM2022

3/N Since low pressure area (LPA) is warm region which expands & warm air rises. Once warm air rises more void will be created. To fill the void more air rushes into LPA. Again, the incoming air become warm & rises. This process continues #Chennairains #Tamilnadurains #NEM2022

4/N Rising air contains huge amount of moisture and once it rises higher in atmosphere the warm air cools because temperature drops with increase in altitude and thats how clouds are formed and fall as rain. #Chennairains #Tamilnadurains #NEM2022

5/5 The more the rising air the more the cloud formation & more the rain.
What if rising warm air has been cut? Then there won't be cloud formation & no rain.
This is what dry air does & eventually weakens the system in matter of few hours.
