The test of numerical prediction of seawater temperature in the sea area near Fujian

A dynamic numerical prediction model of seawater temperature for limited sea area,which was built in the study of the numerical prediction of abnormal seawater temperature in the Huanghai Sea and the East China Sea,is used to test the seawater temperature prediction near Fujian sea area.Essential adjustments have been done according to the features of this region.Two examples are selects.One is in summer (3 d) and the other is in winter (10 d).In the summer test,a typhoon is just passing by and the calculated current field reflects the response of typhoon well.In the winter test,variation tendency of the prediction seawater temperature field agrees with that in reality basically.The absolute mean error in the whole sea area is 0.6℃.The variation of the seawater temperature is mostly affected by the actions of entrainment and pumping.This is related to the topography of the strait.
