We investigated temperature and salinity fields in the Kuroshio recirculation gyre region south of Japan, by using the Argo floats, satellite-derived altimetry data, sea surface temperature (SST) data, and atmospheric reanalysis data. The positive anomalies of temperature in the recirculation gyre region were mainly formed by the horizontal heat advection due to the westward flow associated with the recirculation, and then a vigorous heat was released to the overlying atmosphere in winter in the state of the positive SST anomaly. The salinity in the recirculation gyre region was caused by rainfall in the warm season, which was related to the number of low pressures passing over the recirculation gyre region associated with the location of summertime North Pacific subtropical high.

利用ARGO浮标资料、卫星测高资料、海表面温度(SST)资料和大气再分析资料，研究了日本南部黑潮环流环流区的温、盐度场。环流环流环流区的温度正异常主要是由环流西进引起的水平热平流形成的，然后在冬季以海温正异常的状态向上覆大气释放出一股猛烈的热量。环流涡旋区的盐度是由暖季降水引起的，这与夏季北太平洋副热带高压所在位置通过环流涡旋区的低压个数有关。
