| 摘 要： | 通过对台风过境前后近一个月的MODIS卫星3A级叶绿素a浓度及海表温度数据的比较与分析,发现海表温度,海表叶绿素a浓度均受到较大的影响,其中海表温度平均下降2~3℃,最高下降近10℃;同时叶绿素a浓度在湛江、阳江海域升高约1.43倍,在东海海域平均升高2.44倍,最高可达9.75倍,并且叶绿素a浓度增长有一个约3~5 d的延迟效应。由此可见,利用卫星遥感资料监测台风对海洋叶绿素a浓度、海表表温度等环境参数的变化有应用前景。 |

| Abstract: | In this paper,through the study of MODIS-3A-data of chlorophyll-a and sea surface temperature(SST) before and after typhoon for about one month,the author finds a great effect on SST and chlorophyll-a concentration.The SST averagely falls 2~3℃,even 10℃.The chlorophyll-a concentration rises 1.43 times as much as in the Zhanjiang and Yangjiang Area,but in the East China Sea it averagely rises 2.44 times and the highest increase is 9.95 times as much as its usual status.Moreover,this increase postponed about 3~5 days.Thus it can be seen the potential capacity of using satellite data to detect the variation of marine environmental factors such as chlorophyll-a concentration and SST by typhoon. |
