Wind and cloud structure of monsoon depressions

Abstract

A detailed study of the wind distribution around monsoon depressions using the method of composting is presented. Evolution of the wind field with intensification of the depressions from one-closed-isobar stage to four-closed-isobar stage is discussed. The variation in the slope of the depressions in vertical at different stages of their development is examined. Considering the observed composite wind distribution as a model distribution the wind data so derived may be used for the purpose of supplementing the observational data for objective analysis in real time situations.
 
 Evolution of the cloud structure as seen in INSAT cloud imageries at different stages of development of monsoon depressions in a few typical cases is also examined.
