El Nio Modoki, similar to but different from canonical El Nio, has been observed since the late 1970s. In this paper, using HadISST and NCEP/NCAR wind data, we analyze the relationship between El Nio Modoki and Sea Surface Temperature(SST) in the offshore area of China and its adjacent waters for different seasons. Our results show a significant negative correlation between El Nio Modoki in summer and SST in autumn in the offshore area of China and its adjacent waters, particularly for regions located in the east of the Kuroshio. It is also found that during El Nio Modoki period, anomalous northerlies prevail over the regions from the northern part of the Philippines to the offshore area of China, indicating that the northerlies are unfavorable for the transport of warm water from the western tropical Pacific to the mid-latitude area. Consequently, El Nio Modoki in summer may play a substantial role in cold SST anomalies in the offshore area of China and its adjacent waters in autumn through the influence of the Kuroshio, with a lagged response of the ocean to the atmospheric wind field.
