| Research Abstract |
Surface fluxes have been measured at the center of Lake Kasumigaura. The bu;k coefficients were in agreement with those reported in the literature under mid- to high wind speed ranges. However, in the weak wind speed range, bulk coefficient of momentum was found to increase as the wind speed decreased. Horizontal distribution of annual evaporation (E) was determined with that of surface temperature, wind and humidity data estimated with meteorology data in and around Lake Kasumigaura. It was found that E was the largest at Lake center, with smaller values toward the coastal lines. This was due to the stronger wind regime at the center.
