Intensity variations of the SE-NW-oriented tropical cyclones (TC) in the East China Sea (ECS) passing over the Kuroshio are studied using multi-year high-resolution sea surface temperature data, the tropical cyclone data, and the global reanalysis dataset. The statistical results show that there are 81 TCs passing over the Kuroshio from the southeast in the East China Sea, over 68 years from 1949 to 2016. In terms of the change of the atmospheric pressure in the center of the TC, there are three categories:31 TCs are intensified, 28 maintain their intensities, and 22 weakened. Significant seasonal differences are presented in the distribution. In the analysis on the intensified TCs, it is found that the TCs in the range where the center translational speed is from 1 m/s to 8 m/s and the distance from the Kuroshio main axis is from 10 km to 75 km are intensified more significantly. The analysis of three specific examples of TCs show that the stronger characteristics of the Kuroshio warm water in the ECS, the greater the intensity increase of such tropical cyclones.
