中文摘要：利用MODIS、SeaWiFS 3A资料详细分析了2000—2006年间西北太平洋海域主要台风对叶绿素a浓度的影响。结果发现,台风可导致叶绿素a浓度最大增长平均值为2.385倍,个别最高达10倍以上,且增长到最大值平均延迟5.94d;同时叶绿素a浓度最大值与无台风时叶绿素a浓度具有线性相关性,相关系数达0.889;叶绿素a浓度与相应的海域平均海水深度具有负的乘幂关系,其相关系数是0.87;台风后叶绿素a浓度的最大增长量与相应海域海水平均深度也呈负乘幂关系,其相关性略低于前者,相关系数为0.75。

外文摘要：Using the 3A data of chlorophyll-a （chl-a） from the MODIS and SeaWiFS during 2000-2006, the authors analyzed the effects of typhoon on the chl-a concentration in the northwestern Pacific Ocean. The results show that the maximum increase of chl-a concentration caused by typhoon is on average 2. 385 times that without typhoon, and is over 10 times occasionally, the time by which the chl-a concentration reaches its maximum on average delays by 5.94 days thanks to typhoon. The maximum chl-a concentration during typhoon has a linear relation with that without typhoon, and the correlation coefficient is as high as 0. 889. On the other hand, the chl-a concentration has a negative power relationship with the average depth of the corresponding sea area, and the correlation coefficient is 0.87. The maximum increment of the chl-a concentration after typhoon also has a negative power relationship with the average depth of the corresponding sea area, but the correlation coefficient is 0.75, slightly smaller than during typhoon.
