THE HEAT AND DYNAMIC AIR-SEA INTERACTION IN THE PACIFIC SECTOR OF THESOUTHERN-OCEAN

Meteorological conditions and sea surface heat balance variations in t he section following 67 degrees S between Antarctic peninsula and Ball eni islands and in the quasi-meridional section from 67 degrees S to t he Pennela coast in February/March 1992 were analyzed using the data o f meteorological observations in cruise 6 of r/v ''Academic Ioffe'' ca rried out within the WOCE programme. The anomalous high atmospheric pr essure and a weak cyclonic activity were observed in the studied regio n east of 140 degrees W and relatively low pressure and strong cycloni c activity was registered west of this meridian. The mean heat balance of the sea surface during the period of our work in the section along 67 degrees S proved to be near the zero (1.3 W/m(2)). The sea-surface here received the heat with solar and atmospheric radiation (35.7 W/m (2)) and lost in with the explicit and latent heat fluxes (7.3 and 27. 1 W/m(2) respectively). Wind direction changes account for the main va riations of these fluxes. They intensified during the time of relative ly dry and cold south winds. With more humid and warm northern winds t he latent heat fluxes become weaker, and the explicit heat fluxes usua lly changed their sing, that is the ocean starts to get the heat from the atmosphere. The results of this study were compared with the liter ary data.
