A STUDY ON PROCESS OF HEAT TRANSFER AT SEA SURFACE LAYER BASED ON MEASUREMENT DATA

Abstract

 Water temperature distribution in enclosed water area, especially from water surface to 0.5m under water surface, was measured with weather information, wind, solar radiation. Seasonal change of vertical thermal distribution including violent weather effect is presented.Based on the measurement data, latent heat flux and sensible heat flux are estimated. Moreover thermal diffusivity in the water surface layer with 0.5m depth is evaluated. Finally, thermal flux between water surface and atmosphere is discussed with considering thermal supply from deeper water to water surface.
