摘要
通过对卫星海表面温度(SST)数据的处理,发现2006年6月在127.98°E,29.8°N附近有锋面涡产生,从产生到消散整个周期为7天,空间尺度最大达到200km。多年卫星观测及现场测量表明,该区域因是黑潮水与陆架水相互穿插区域,故是锋面涡的多发海域。本文利用多传感器卫星数据观测到锋面涡产生、移动、融合和消散的整个过程,并分析了锋面涡产生的原因。结果表明风对本次锋面涡的产生有一定作用,同时也是锋面涡消失的原因之一。
Using multi-sensor satellite data,a cold eddy was found at the place of 127.98 E and 29.8 N,in June 2006,with 7 days period and 200 km west-east spatial scale.Many year satellite monitorings show that it occurred many times in this area.The whole process includes generation,motion,merge and evanesce.Combining multi-satellite data,we analyze the effect of wind on the generation and evanescence of frontal eddy.This study shows that the wind is the main inducement,and at the same time is also one of the reasons of the evanescence of frontal eddy.
