利用台风年鉴、美国国家环境预报中心（NCEP）和遥感系统（RSS）的数据，对西北太平洋海面温度（SST）对台风的响应进行了研究。选取了六个台风因子和四个SST因子来研究这种响应。结果表明，台风对SST的影响取决于台风的强度。在SST与台风因子之间的所有相关系数中，SST下降与气压梯度和气压差之间的相关系数最大，而SST下降与台风移动速度之间的相关系数最小。由于海面降温还与上层海洋状况高度相关，讨论了上层海洋结构与海面降温之间的关系，结果表明，在深度大于100米的区域，响应随水深增加而减小；随着混合层加深，SST降温减小，但不是单调的。
The response of the sea surface temperature(SST) to typhoons in the Western North Pacific Ocean was investigated using data from typhoon yearbook,NCEP and Remote Sensing Systems(RSS).Six typhoon factors and four SST factors were chosen to study the response.The results suggest that the influence of typhoons on the SST depends on the intensity of the typhoon.Among all the correlation coefficients between the SST and typhoon factors,the correlation coefficients between SST decrease and air pressure gradient and pressure difference were found to be the largest,while the correlation coefficient between SST decrease and typhoon translationspeed was found to be the smallest.As the sea surface cooling is also highly related to the upper ocean condition,the relationship between the upper ocean structure and sea surface cooling was discussed and the results indicate that the response decreased with the increase of water depth in areas deeper than 100 m;with the deepening of the mixed layer,the SST cooling decreased,but not monotonously.
