EVAPORATION AND SENSIBLE HEAT FLUX OVER THE ARCTIC OCEAN.

Description
Summary:These fluxes were calculated for each month over the Polar Ocean and the Norwegian-Barents Sea. Sverdrup's evaporation formula was used, and it was first examined how the K-coefficient in that formula depends on the wind speed frequency distribution. Seasonal maps were constructed of mean wind speed. Previously obtained surface temperatures were used, but some additional examinations were carried out, using various assumptions for extreme surface temperatures in summer and winter. Evaporation and sensible heat flux were calculated separately for the following areas: Central Polar Ocean, Kara-Laptev Sea, East Siberian Sea, Beaufort Sea, and belts of 5 degrees latitude of the Norwegian - Barents Sea. The values for the different areas are presented in tables and figures. Evaporation over ice surfaces has a double maximum in spring and fall - and a main minimum in winter. Over open water surfaces the evaporation shows a summer minimum and a broad maximum in winter. If small parts of the ocean were to remain open longer in fall, or during the whole winter, the heat loss would increase very rapidly.
