摘要

利用海洋和大气再分析数据和观测资料,研究了近陆加强热带气旋和非近陆加 强热带气旋过境时沿岸浅层海水的响应。当 NLI-TC 接近陆地时,NLI-TC 轨道前方的海面温度保持不变,甚至有所上升。在NLI过程中起重要作用的风应力的大小与路径右侧的地带性表面风有关。沿岸混合层的增温可以用海面风力强迫下持续风应力作用下的 Ekman 输运来解释。沿岸海域边界层的连续加深和表层下海水温度平均上升 0.3℃,可以在一定程度上保持热容量。这种沿岸浅水响应可以部分解释南海北部 NLI 的进展,表明了沿岸海洋动力学和海气相互作用的重要性。

Shallow Coastal Water Responses During the Near Landfall Intensification of Tropical Cyclones in the South China Sea

Shallow coastal seawater response during the passage of near-landfall intensification (NLI) tropical cyclones (TCs) and non-NLI TCs was examined using oceanic and atmospheric reanalysis data and observations. The sea surface temperature ahead of the NLI-TC track is maintained or even increases when NLI-TC is approaching the land. The magnitude of the wind stress, which play an important role in the NLI process, is related to the zonal surface wind on the right side of the tracks. Coastal mixed layer warming can be explained by Ekman transport under sustained wind stress due to surface wind forcing. The successive deepening of the coastal ocean boundary layer and the increase in warming in the subsurface seawater temperature by an average of 0.3°C, could maintain thermal capacity in a certain degree. This shallow coastal water response could partly explain the NLI progress in the northern South China Sea, indicating the importance of coastal ocean dynamics and air-sea interactions.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
