摘要
台湾东北海域 NOAA卫星 AVHRR反演的 MCSST图像表明 ,黑潮进入东海时产生的中尺度暖涡对上升流 (或冷涡 )有明显的调制作用。为证实这一现象 ,我们通过对中尺度暖涡流场结构分析 ,提出了中尺度暖涡诱导陆架上升流的必然性。利用有耗散的层结流体中的慢环流理论 ,导出了由中尺度涡诱导的陆架上升流流场解析表达式 。
On the basis of NOAA satellite MCSST image, we found that the mesoscale warm eddy produced by Kuroshio flow into the East China Sea has remarkable effect of modulation on upwelling. The structure of mesoscale warm eddy was analyzed in order to verify this phenomenon. The necessity of shelf upwelling induced by mesoscale eddies was thus confirmed. The slow circulation theory of dissipative stratified fluid was used to derive the analytic expression for shelf upwelling induced by mesoscale eddy. The result proves the reasonability of the theory on the upwelling induced by mesoscale warm eddy in north-east sea of Taiwan.
