ABSTRACT: This paper focuses on the investigation of sea surface temperature (SST) and the rainfall variations due to typhoon CHAN-HOM and Nangka occurred in 2015 over Northwest Pacific Ocean (NPO). On 7-13 July, the SST cooling area occurred mainly in the middle of the two typhoons track, the maximum SST decline reached more than 4℃during typhoon CHAN-HOM and Nangka passage. Due to the collective effect of typhoon CHAN-HOM and Nangka, the SST cooling phenomenon maintained for about 15 days. Typhoon CHAN- HOM and Nangka produced heavy rainfall and the maximum daily rainfall was 120 mm (8 July) and 130 mm (11 July). In a1, c area, the average temperature and rainfall basically showed a positive correlation with correlation coefficient of 0.54, while on area a2, the correlation coefficient was﹣0.6.
