The spatial variability of the structure of the lower troposphere over the north western Indian Ocean during the period 12th July to 2nd September, 1983 has been studied using the upper air data collected during the first scientific cruise of @iORV Sagar Kanya@@. An analysis of thermodynamic structure and kinematics of the marine boundary layer for different zonal and meridional sections revealed the following: (a) Temperature and humidity inversions were absent throughout the study area except over a few locations in the western region; (b) Large scale subsidence was found over the Central Equatiorial Indian Ocean; (c) The convective activity over the western Indian Ocean was found to be moderately suppressed as compared to the eastern region; (d) The zonal and meridional components of winds along the Equator and 10~'N zonal sections exhibited a mirror image like distribution
