Model calculation of air-sea heat fluxes over ocean area near China

The sensible and latent heat fluxes over the ocean area near China were calculated and analyzed by using the Uoddard Earth Observing System (GEOS)-Four-Dimensional Data Assimilation System (DAS).The calculated results showed that the sensible heat flux had its large value in winter and autumn,small value in spring and summer over the ocean area near China.In winter,the sensible heat flux increased distinctly with latitulle,and its isolines were very crowded.Over the ocean area east of Taiwan and south of Japan,the direction of isoline was from southwest to northeast.In the South China Sea,the sensible heat flux was lower than that of surrounding ocean areas,and its isoline was distributed into a type of an inverted trough.In autumn and winter,the maximum center of latent heat flux appeared over the ocean area northeast of Taiwan and south and southeast of Japan,meanwhile,the isoline was in the direction of southwest to northeast.In spring and summer,the latent heat flux had minimum value in the Huanghai Sea: At the same time,the maximum value center of latent heat flux appeared over the ocean area south of Japan in spring.
