In May and early June of 1999 the Joint Air-Sea Monsoon Experiment (JASMINE) was conducted in the Indian Ocean and Bay of Bengal aboard the NOAA R/V Ronald. H. Brown. A group of government laboratory and university researchers cooperated on this investigation of ocean, near-surface, and atmospheric processes before and during the summer monsoon. The ship made several transects from south of the equator to 12 degrees N. latitude along 89 E. longitude. Two 5-day surveys were also conducted near 10 degrees N. latitude; the first survey was in suppressed conditions and the second was in fully developed monsoon conditions. In this paper we will give results of preliminary analysis of the air-sea flux data including cruise- averages plus suppressed versus disturbed conditions. The results will be compared with nine other tropical cruises (including three in TOGA COARE) by the ETL air-sea flux group.
