Study Of Air-sea Interface Turbulent Heat Fluxes Of Neighboring Seas Of CHINA

In this paper, in order to obtain detailed information of air-sea interface sensible and latent heat fluxes in the neighboring seas of China, especially, to ascertain pivotal parameter—heat and moisture transfer coefficients, I bought forward transfer coefficients according to different regions and seasons. So, we can describe the main temporal and spatial properties of heat fluxes of neighboring seas of China, which is quite import when deeply studying the air-sea interaction. COARE3.0a is one of advanced model aiming at computing air-sea interface heat fluxes. By analyzing and comparing the effects of two corrections in the COARE3.0a when calculating heat fluxes of neighboring seas of China, I thought some error caused by simpleness can be ignored, including neglecting the cool-skin and warm-layer effects on sea surface temperature, and applying the Charnock's wave parameterization to all of the aera. Applying the simplified COARE3.0a to observed data of 4 stations, we got transfer coefficients of these 4 stations, and successfully simulated the main characters of heat fluxes under summer monsoon at Xisha's Yong-xing Island during 2002.5.1-31. Using GSSTF2 data and NCEP/NCAR reanalysis data set, and aplying the simplified COARE3.0a to the neighboring seas of China, we can define the heat and moisture transfer coefficients of different regions and seasons, which is accord with the result of above-mentioned 4 stations very well. Improved Bulk method is straightforward and convenient to use. It can depict the main temporal and spatial properties of neighboring seas of China. Comparing it with GSSTF2 data, NCEP/NCAR reanalysis data set, and observed station data set, we found the improved method can not only achieve the precision of COARE3.0a, but also picture the details of heat fluxes of neighboring seas of China more clearly and more rationally.
