Diel variations of heat fluxes across the air-sea interface from the Bay of Port Blair

Raj, Shammi and Varkeyachan, P V and Murty, A V S (1990) Diel variations of heat fluxes across the air-sea interface from the Bay of Port Blair. In: Proceedings of the first workshop on scientific results of FORV Sagar Sampada, 5-7 June 1989, Kochi.



The heat fluxes of sensible and latent heat over the May of Port Blair in August and September, 1988 based on the surface meteorological data collected over a period of 24 hrs in each month at an interval of 1 hour have been represented on the timescale. The latent heat throughout the 24 hrs of the day was positive during August and the air layer remained below saturation level. During September Intent heat transfer was from air to sea (ie. negative) during the period 0700 - 1500 hrs indicating that condensation has taken place. This was supported by the observation of drizzling during the period with saturated condition of the air layer in the latter month. During the day time hours in both months, the relative humidity range was from 70 to98%. Probably the high water vapor content in the air gets heated up higher than the sea surface. This may be one of the possible reasons for the transfer of sensible heat from air to sea surface during daylight hours. During the rest of the hours of the day the transfer of heat was from sea surface to air in both the months.
