【摘要】：利用Aqua卫星搭载的MODIS传感器数据,分析了慢速移动的强台风"鲶鱼"(Megi,2010)对中国南海北部海表面温度(SST)、海表面叶绿素a浓度(Chl-a)、初级生产力(PP)和渔业资源的影响。结果显示在研究区域内,SST平均值从台风前的28.8℃下降到台风后的25.6℃,SST最大下降5℃;Chl-a平均值从台风前的0.099 mg?m 3上升到0.731 mg?m 3,增长6.4倍。应用初级生产力垂向归纳模型反演PP,结果表明台风"鲶鱼"极大的提高了研究区域的PP,台风过后8 d内PP为1001.5 mg?(C?m2?d) 1,比2001—2009年间平均值增加684.9 mg?(C?m2?d) 1;根据台风后8d PP估算此次台风额外固碳1.01 Mt。应用营养动态、Tait和Cushing模型估算台风引起的渔业资源增量为10.1×104 t。表明慢速移动的强台风对于渔业资源生产量有较大影响。
