吕宋海峡Ekman输运和南海SST的相关性分析
Correlation analysis between Ekman transport through the Luzon Strait and SST in the South China Sea
摘要
Abstract
Based on the wind data archived in the National Center for Environmental Prediction (NCEP) from 1950 -2009, Ekman transport through the Luzon Strait (ETLS) is calculated. It is shown that ETLS is from the western Pacific Ocean to the South China Sea (SCS) all the year except in summer, and varies significantly with seasons. Correlation analysis indicates a positive relationship between ETLS and sea surface temperature (SST) in the SCS on the seasonal scale. The influence of ETLS on the SST starts after the first month and extends from the northern to the southern part of the basin in the SCS, reaches the maximum significance in the second month throughout the whole basin, decays in the third month and disappears in the fourth month. On the interannual scale, the ETLS anomaly is significantly related with the second mode of SST anomaly (SSTA) with a correlation index positive and negative in the northern and southern SCS, respectively. The basin-scale circulation in the SCS is modulated by the ETLS because the SST varies with the advection of cold or warm waters.关键词
