Question:-
What is upper atmospheric circulation?
Answer:-
☆ In the northern hemisphere, subtropical high pressure belt gives rise to permanent winds. They blow towards the equatorial low pressure belt by reflecting towards the west and are called trade winds. The German word 'trade' means 'track' and stands for the blowing steadily in the same direction and in a constant course. India lies in the belt of dry north- East trade winds.
☆The climate of the India is also affected by the movement of upper air current know as 'jet stream' . These are fast flowing air current in a narrow belt in the upper atmospheric, above 12,000 m. The speed varies from about 110 km/h in summer to about 184 km/ h in winter. An easterly jet stream develops at about 25° N latitude. A jet stream causes the neighbouring atmosphere to cool . This cooling effect of the easterly jet stream causes rain from clouds already found over this latitude (25°N) .
