The wind - driven circulation and its dynamical mechanisms in the south china sea ( scs ) were studied numerically using ecom - si model with 10 " x 10 " horizontal resolution and 20 sigma levels . the present work focuses on the barotropic circulation in winter and summer 本文用ecom - si模式, 10 ’ 10 ’水平分辨率,垂向20個(gè)層,由h / r ( 1983 )氣候?qū)W月平均風(fēng)應(yīng)力場(chǎng)和開邊界流量驅(qū)動(dòng),模擬了南海風(fēng)生環(huán)流的季節(jié)變化,并針對(duì)南海冬夏季風(fēng)生正壓環(huán)流的動(dòng)力機(jī)制進(jìn)行了數(shù)值實(shí)驗(yàn)。
