日本南部使用设置在渡船上的温度计测量了海面温度（SST），以调查从黑潮侵入沿海地区的暖水的特征。对1987年4月至1989年9月的卫星图像海温数据和水文观测数据进行时间序列分析。结果表明，黑潮暖水间歇性地侵入远州滩和熊野滩沿岸地区，周期分别约为50天和20天，与黑潮路径和黑潮锋面扰动的波动有关。当黑潮采取固定小曲流路径（B 型和 C 型）时，以 50 天为周期的入侵占主导地位。暖水以20 cm s−1的速度向西扩散，估计深度至少为150 m，提供足够的热量来弥补沿海地区蒸发造成的损失。在黑潮直线路径上，检测到暖水侵入沿海地区的时间只有20天。入侵周期为20天的暖水以25 cm s−1小规模向西扩散。
Sea surface temperature (SST) has been measured in the south of Japan using a thermometer set up in the ferry boat to investigate the characteristics of the warm water intrudes into the coastal areas from the Kuroshio. Time series analysis was applied to the SST data with satellite images and hydrographic observation data from April 1987 to September 1989. The results indicate that the warm Kuroshio water intruded into the coastal areas on the Enshu-nada and the Kumano-nada Seas intermittently with periods of about 50 and 20 days associated with the fluctuation of the Kuroshio path and the Kuroshio frontal disturbance respectively. The intrusion with a 50-day period was dominant when the Kuroshio took a stationary small meander path (B- and C-types). The warm water spread to the west at 20 cm s−1, and was estimated to have a depth of 150 m at least and supply enough heat to make up the loss due to the evaporation in the coastal area. During the straight path of the Kuroshio, it was detected that the warm water intruded into coastal areas only with a 20-day period. The warm water that intrudes with a period of 20 days spreads to the west at 25 cm s−1 in a small scale.
