The daily FY2E Sea Surface Temperature (SST) data from China National Satellite Meteorological Center (NSMC) was evaluated and compared with the Optimum Interpolation Sea Surface Temperature (OISST) data from US National Oceanic and Atmospheric Administration (NOAA) over Northwest Pacific Ocean (NPO) in this study. The results show that the distribution of FY2E SST is close to OISST in tropical region over NPO, especially in typhoon active season, but the value of FY2E SST is a little lower than that of OISST in tropical ocean, with the absolute deviation 1°C lower and the relative deviation about 6% lower. The correlation coefficient between monthly FY2E SST and monthly OISST is as high as 0.7, which passes the t-test at a significance level of 0.01. Based on the evaluation result, the merged SSTFY over NPO is calculated using a weighting function. Besides, Tropical Cyclone Heat Potential (TCHPFY) is calculated and combined with the simulated sea temperature profile. From three years operational tests in NSMC, the merged SSTFY and TCHPFY are shown to be good indexes in monitoring and predicting the intensity of tropical cyclones (TCs) over NPO.
