Meridional circulation associated with the monsoons of India


  • Y. P. RAO



Meridional components in January and July at twelve Indian Rawin stations and Colombo, Nairobi, Aden, Bahrein and Tashkent based on three years' data are presented. The centres of direct and indirect cells are located at higher elevations, probably to overcome the obstruction to meridional exchange from high mountain ranges running east to west. At Bahrein and Aden the upper southerlies of the direct cell are absent in winter. The direct cell retreates northward to near 30oN in July and a ‘monsoon cell’ with lower southerlies and upper northerlies occupies the Indian area from 26 to 13°N, Northerlies at Colombo and Trivandrum in the lower troposphere in July suggest that the feed across the equator into the Arabian Sea branch of the monsoon may be extremely limited.
