西北太平洋中尺度涡上的海气参数异常特征分析
Analysis of air-sea parameter anomalies associated with mesoscale eddies in the Northwestern Pacific
摘要
Abstract
Mesoscaleeddies play a pivotal role in oceanic material transport,energy exchange,and climate variability modulation.To understand their impacts on air-sea interactions in the Northwestern Pacific,this study analyzes satellite altimeter and scatterometer data(2006-2009)using eddy identification and composite analysis techniques,focusing on over 30 000 warm and cold eddies.Results demonstrate distinct air-sea parameter anomalies:warm(cold)eddies exhibit positive(negative)anomalies in sea surface temperature(SST,1.64/-1.58 ℃),surface wind speed(0.72/-0.58 m/s),sensible heat flux(19.60/-39.25 W/m2),and latent heat flux(40.98/-55.03 W/m2);these atmospheric responses show strong linear coupling with SST anomalies,with maximum coefficients of 0.49/0.50 m/(s·℃)(wind),19.57/20.04 W/(m2·℃)(sensible heat),and 33.61/32.96 W/(m2·C)(latent heat).Regional and seasonal variations in anomalies are modulated by background SST gradients and wind fields through vertical heat transport efficiency and surface roughness modification;synergistic mechanisms involving Ekman pumping,mixed layer adjustment,and boundary layer stability further contribute to these patterns.This study underscores the need for eddy-resolving coupled models to quantify mechanistic contributions and provides critical insights for improving air-sea parameter forecasting in eddy-active regions.关键词
