摘　　要：基于实测的CTD资料,分析了台湾海峡以北海域一个逆温层结构的季节性变化。通过对逆温层垂向温盐的分布统计,温盐散点图的分析结果显示,在逆温层出现的站位,盐度的梯度很好的补偿了温度逆转,表明了在盐度层面研究逆温层现象的可行性。Based on the CTD observations to the north of Taiwan Strait,this paper analyses the structure and seasonal variability of the temperature inversion near Zhejiang-Fujian coast. The results shows that the temperature inversion exist in all the seasons except for summer. The strength of the temperature inversion is the strongest in winter, weaker in fall and the weakest in spring. In summer, the Changjiang diluted water （CDW） expands to the north direction, and the air-sea heat flux is positive （the ocean gains heat ）, both of which contribute to the erosion of the temperature inversion. However,in wintertime,the CDW heads south due to the effect of the monsoon system, and the ocean loses heat into the atmosphere, to strengthen the inversion. The stratification is steady due to the compensation of the salinity effect. Therefore, it is significant that the salinity contributes to the density through the scatter plots of salinity and temperature.
