The study has been made from mean monthly velocities. The land and sea breezes which are the most important variations in Bombay, are found to be related with diurnal variation in pressure distribution over a wide area especially caused by the land distribution of that region. The land breeze is associated with a. high and the sea breeze with a' low '. The vertical extent of the sea breeze is found to coincide with the level where the' low' changes to ' high '.
The afternoon winds over Poona are found to be antitriptic in the lower leve'1s and they continue to be weak at higher levels due to weak pressure gradient. In some. of the non-monsoon months katabatie winds Over Poona .are found perceptible even up to 150 metres above ground level.
