Abstract

Indian summer monsoon has a large inter-annual as well as intra-seasonal variability over temporal and spatial scales. Onset dates, monsoon activity within a monsoon season and quantity of monsoon rainfall are also found to vary from year to year. One important synoptic feature associated with the onset of monsoon is the existence of a strong cross equatorial low level jet (LLJ), with its core around 850 hPa over the Indian Ocean and South Asia. This LLJ generally supports the large-scale moisture and momentum transport from ocean to atmosphere and the consequent rainfall over the Indian mainland. In the present study, buoy data at a stationary position in the Arabian Sea (15.5°N, 61.5°E) have been used to understand the air-sea interface processes before, during and after the onset of monsoon 1995.
