What are the characteristics of anticyclonic circulations, and how do they influence weather patterns over the Indian subcontinent?
Main Body
Influence on Weather patterns of India 1) Creation of Thar desert along 25-30°N due to Sub-tropical westerly jet stream's trough over N-W India => mechanical sinking of air. 2) Responsible for reversal of monsoon winds. Eg: North-East Monsoon - anticyclonic stable conditions due to sinking air and relatively colder surface over NW India. 3) Inversion of temperature => marked by anticyclonic stable calm clear conditions as cold air is superimposed by warm air. 4) Droughts, heatwaves, pollution domes, urban heat islands etc. due to anticyclonic conditions. Eg: Omega blocking of India.
Conclusion
Therefore, anticyclonic conditions are responsible for the macro & micro climatic variations.
