【摘要】：利用垂直一維物理-生物耦合模型模擬了臺(tái)風(fēng)"派比安"和超強(qiáng)臺(tái)風(fēng)"珍珠"對(duì)南海北部水溫、營(yíng)養(yǎng)鹽和葉綠素垂直分布的影響,并估算了2次臺(tái)風(fēng)對(duì)初級(jí)生產(chǎn)力和營(yíng)養(yǎng)鹽垂直輸送的貢獻(xiàn)。結(jié)果表明,"派比安"引發(fā)50m以淺海水溫度降低,表層降溫2.0℃,50~130m海水溫度升高,混合層加深30m,海表葉綠素濃度增加0.18mg·m~(-3),營(yíng)養(yǎng)鹽垂向輸運(yùn)對(duì)初級(jí)生產(chǎn)力的貢獻(xiàn)為2.3×103 mg C·m~(-2),約占全年的3%。"珍珠"引發(fā)55m以淺海水溫度降低,表層降溫超過5.0℃,55~150m海水溫度升高,混合層加深85m,海表葉綠素濃度增加0.9mg·m~(-3),帶來(lái)的營(yíng)養(yǎng)鹽垂向輸運(yùn)量約為全年的30%,對(duì)初級(jí)生產(chǎn)力的貢獻(xiàn)為12.8×103 mg C·m~(-2),約占全年的18%�？梢�,臺(tái)風(fēng)過程,特別是強(qiáng)臺(tái)風(fēng)過程對(duì)上層海洋的初級(jí)生產(chǎn)和生物地球化學(xué)過程具有顯著影響。臺(tái)風(fēng)的強(qiáng)度和移動(dòng)速度等自身特征是決定海洋環(huán)境要素對(duì)臺(tái)風(fēng)響應(yīng)程度的核心要素,同時(shí)臺(tái)風(fēng)過境前的水體層化狀態(tài)和營(yíng)養(yǎng)鹽水平也是不可忽視的因素。
[Abstract]:The vertical one-dimensional physical-biological coupling model was used to simulate the effects of typhoon Pibian and super typhoon Pearl on the vertical distribution of water temperature, nutrients and chlorophyll in the northern part of the South China Sea. The contribution of two typhoons to primary productivity and vertical transport of nutrients was estimated. The results showed that the temperature of "pipion" was 50 m in shallow seawater, the temperature of surface water was increased by 2.0 鈩，
