Abstract

The time evolution of the large-scale circulation over south Asia during the withdrawal phase of the Indian summer monsoon from August to November is examined for the years from 1979 to 1984 using FGGE Level III-b and ECMWF operational analysis data. During the withdrawal of the Indian summer monsoon, three distinct stages of abrupt transitions are recognized. The southward shift of 200 mb subtropical Jet stream round the Tibetan plateau, weakening of 850 rob westerlies around the Indian subcontinent, decrease of rainfall the west coast of India, and/or sharp drop of 300 rob zonal mean temperature over the Eurasian continent occur almost simultaneously associated with these transitions.
