摘要

Abstract

This paper investigates the response of the thermocline depth (TD) in the South China Sea (SCS) to the El Niño-Southern Oscillation (ENSO) events using 51-year (from 1960 to 2010) monthly seawater temperature and surface wind stress data acquired from the Simple Ocean Data Assimilation (SODA)

together with heat flux data from the National Centers for Environmental Prediction (NCEP)

precipitation data from the National Oceanic and Atmospheric Administration (NOAA) and evaporation data from the Woods Hole Oceanographic Institution (WHOI). It is indicated that the response of the SCS TD to the El Niño or La Niña events is in opposite phase. On one hand

the spatial-averaged TDs in the SCS (deeper than 200 m) appear as negative and positive anomalies during the mature phase of the El Niño and La Niña events

respectively. On the other hand

from June of the El Niño year to the subsequent April

the spatial patterns of TD in the north and south of 12°N appear as negative and positive anomalies

respectively

but present positive and negative anomalies for the La Niña case. However

positive and negative TD anomalies occur almost in the entire SCS in May of the subsequent year of the El Niño and La Niña events

respectively. It is suggested that the response of the TD in the SCS to the ENSO events is mainly caused by the sea surface buoyancy flux and the wind stress curl.
