台风“麦莎”对西北太平洋近岸和离岸浮游植物叶绿素浓度的影响
Influence of Typhoon Matsa on Phytoplankton Chlorophyll-a in the Northwest Pacific Ocean Offshore and Alongshore
摘要
Abstract
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.关键词
