| Abstract: | Surface meteorological parameters acquired during the field phase experiment, BOBMEX-99, for the stationary periods (SP I
and II) of the ship ORV Sagar Kanya over Bay of Bengal have been analysed. Active and weak monsoon conditions were observed
during the first and the second phase of the experiment respectively over India as well as over the stationary ship location.
The phase mean sea surface temperature (SST) is found to be the same in both the phases, however large differences have been
observed in the phase mean values of wind speed, mean sea level pressure, latent heat and momentum fluxes at air-sea interface.
Synoptic scale monsoon disturbances formed only during the period of strong north-south pressure gradient over the Bay region.
Events of prominent fall in SST and in the upper 15 m ocean layer mean temperature and salinity values during typical rainfall
events are cited. The impact of monsoon disturbances on ocean-atmosphere interface transfer processes has been investigated. |
