Abstract
The diurnal variation of upper winds over the Indian sub-continent has been examined with reference to the normals of upper winds from pilot balloon ascents taken near about 0200,0700 and 1500 lST upto 6 km. This has been accounted for as mainly due to differential heating or cooling of the various parts of the country associated with the vertical movement of air due to convection and an expression has been derived connecting diurnal variation with the differential heating and vertical movement. Differential heating of land and sea. areas are found to affect winds upto 3 km in general and upto 6 km in April, the effect in the lower levels being more prominent in the west coast than in the east coast. Some notable instances of the diurnal variation which have an effect on the climatology of the various regions are also considered.
