【摘要】：2014年第9號超強臺風"威馬遜"(1409)過境南海并穿越瓊州海峽進入北部灣,給海南、廣東和廣西造成了嚴重損失,并對南海西北海域海洋動力與生態(tài)環(huán)境產(chǎn)生了重要的影響。文章利用衛(wèi)星遙感水色水溫及風場數(shù)據(jù),分析了臺風前后海表溫度、懸浮泥沙濃度、葉綠素濃度、初級生產(chǎn)力及上升流分布特征與變化。研究結(jié)果表明:超強臺風"威馬遜"誘發(fā)了強烈的混合夾卷和上升流,并加強了季節(jié)性上升流;海表溫度最大降幅近2℃,相對臺風路徑呈顯著的"右偏性",而臺風引起的強降水卻具強烈的"左偏性";臺風后懸浮泥沙濃度平均升高51.4%,葉綠素濃度增幅達28%,且最大濃度有3d的延遲,初級生產(chǎn)力增加34%;上層水體混合加劇,混合層深度平均增長近10.4m。
[Abstract]:The Super Typhoon Weimason 1409 (No. 9 of 2014) transiting the South China Sea and crossing the Qiongzhou Strait into the Beibu Gulf has caused serious losses to Hainan, Guangdong and Guangxi, and has had an important impact on the marine dynamics and ecological environment in the northwest waters of the South China Sea.Using satellite remote sensing data of water color water temperature and wind field, the characteristics and changes of sea surface temperature, suspended sediment concentration, chlorophyll concentration, primary productivity and upwelling before and after typhoon were analyzed.The results show that Super strong Typhoon "Weimason" induces strong mixed convection and upwelling, and strengthens seasonal upwelling, and the sea surface temperature decreases by nearly 2 鈩，
