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1.17 mg·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。

In this paper, the impact of an intense, fast moving Typhoon "Matsa" on phytoplankton chlorophyll-a (Chl-a) concentration is investigated. By using the satellite remote sensing data, the changes of chlorophyll a concentration, SST and wind speed in pre- and post-typhoon, are analyzed and the different performances of the Chl-a concentration responses between alongshore and offshore waters are preliminarily discussed. The research results show that the Typhoon "Matsa" has a great influence on the East China Sea. There are significant responses of SST in both offshore and alongshore area. In the offshore area east of Taiwan, the SST reduced from 29°C to 26.4°C during the typhoon, and recovered to 27.8°C after it passed. In the southeast coastal of China mainland, the SST reduced from 28.6°C to 26.1°C during the typhoon, and recovered to 27.8°C post-typhoon. The offshore area kept at a low level of Chl-a concentration, it increased from 0.0489mg·m-3 pre-typhoon to 0.0821mg·m-3 post-typhoon gradually. In the alongshore area, high Chl-a concentration had a sharp decrease from 1.83mg·m-3 to 0.73mg·m-3 during typhoon, and restored quickly back to pre-typhoon level of 1.17 mg·m-3 in two days. The Chl-a concentration presented a negative correlation with the wind speed in the alongshore during the typhoon, which is significantly different to the responses in the offshore waters.
