【摘要】：2014年第9號(hào)超強(qiáng)臺(tái)風(fēng)"威馬遜"(1409)過(guò)境南海并穿越瓊州海峽進(jìn)入北部灣,給海南、廣東和廣西造成了嚴(yán)重?fù)p失,并對(duì)南海西北海域海洋動(dòng)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(fēng)場(chǎng)數(shù)據(jù),分析了臺(tái)風(fēng)前后海表溫度、懸浮泥沙濃度、葉綠素濃度、初級(jí)生產(chǎn)力及上升流分布特征與變化。研究結(jié)果表明:超強(qiáng)臺(tái)風(fēng)"威馬遜"誘發(fā)了強(qiáng)烈的混合夾卷和上升流,并加強(qiáng)了季節(jié)性上升流;海表溫度最大降幅近2℃,相對(duì)臺(tái)風(fēng)路徑呈顯著的"右偏性",而臺(tái)風(fēng)引起的強(qiáng)降水卻具強(qiáng)烈的"左偏性";臺(tái)風(fēng)后懸浮泥沙濃度平均升高51.4%,葉綠素濃度增幅達(dá)28%,且最大濃度有3d的延遲,初級(jí)生產(chǎn)力增加34%;上層水體混合加劇,混合層深度平均增長(zhǎng)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，
