摘要(Abstract)：

研究了一个强度较强、移动较快的台风"麦莎"对浮游植物叶绿素a浓度的影响。利用卫星遥感资料,分析了台风"麦莎"经历前后海表叶绿素a浓度、海表温度(SST)和风速的变化,并初步讨论了近岸与离岸海域海表叶绿素a浓度在台风影响下的不同响应。结果表明,台风"麦莎"对东海海域产生了较大影响。台风路径附近的近岸、离岸海域SST响应都十分明显,台湾岛以东的离岸海域SST平均值约由台风前29°C降为台风中的26.4°C,台风后回升至最大值27.8°C。中国大陆东南沿海的近岸区域SST从台风前28.6°C达到台风中最低值26.1°C,台风后回升至最大值28°C。离岸海域海表叶绿素a浓度始终保持在较低的水平,由台风前0.049 mg·m-3增长至台风后0.077 mg·m-3,在台风期间保持缓慢增长的趋势。而近岸区域在强烈风场的影响下,近岸台风发生前存在的较高值区出现了急剧的衰减,由台风前1.83 mg·m-3降至台风中0.73 mg·m-3,并在台风过境后两天迅速回升至1.17mg·m-3。台风期间近岸海域海表叶绿素a浓度和风速呈负相关,台风后近岸海域叶绿素a浓度恢复至台风前水平时间很短,出现了与离岸海域截然不同的响应变化。
