Test of numerical prediction of sea water temperature in the Taiwan Strait

INTRODUTION ln the ocean environrnent prediction nurnerital medels in the China seas, the TaiwanStrait was usually considered as oPen boundary either in the study of the East China Ai or thefouth China As, so it is difficult to get a satisfactory predicted result in this strait area.Recently many stud1es on the Taiwan Strait have been made, arid the predlction serviceproects of the drine prediction stage are increasing and have achieved high--favorable econodricbenefit.

Test of numerical prediction of sea water temperature in the Taiwan Strait

A dynamic numerical prediction model of sea water temperature for limited sea area is used to predict the sea water temperature at the sea area near Fujian. Essential adjustments have been made in accordance with the characteristics of this region. Two tests have been made. 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 well responds to typhoon. In the winter test, variation tendency of the predicted sea water temperature field agrees with that of the observation basically, the absolute mean error in the whole sea area is 0.6 ℃. The variation of the sea water temperature is mostly affected by entrainment and pumping, which is related to the topography of the strait.
