摘要利用一系列高分辨率卫星资料和区域大气模式研究了春季东海黑潮锋的大气响应。在春季，快速散射计（QuikSCAT）风速显示出明显的海表温度（SST）效应，在暖（冷）舌上观测到高（低）风速。SST和地面风速之间的这种同相关系表明SST对大气的影响。风辐合出现在黑潮锋较暖的一侧，并伴有一条狭窄的雨带。星载雷达资料分析表明，春季黑潮暖舌上出现深对流，对流降水增强，积云对流频繁，降水（云顶）高度增加。这些深对流活动...
AbstractThe atmospheric response to the spring Kuroshio Front over the East China Sea is investigated using a suite of high-resolution satellite data and a regional atmospheric model. The atmospheric response appears to extend beyond the marine atmospheric boundary layer, with frequent occurrence of cumulus convection.In spring, Quick Scatterometer (QuikSCAT) wind speed shows a clear effect of sea surface temperature (SST), with high (low) wind speed observed over the warm (cold) tongue. This in-phase relationship between SST and surface wind speed is indicative of SST influence on the atmosphere. Wind convergence is found on the warmer flank of the Kuroshio Front, accompanied by a narrow rainband. The analysis of satellite-borne radar measurements indicates that deep convection appears over the Kuroshio warm tongue in the spring season, with enhanced convective precipitation, frequent occurrence of cumulus convection, and increased precipitation (cloud) tops in altitude. These deep convective activities ...
