Sea surface temperature (SST) is important for marine environment, and the variation of SST in the North Indian Ocean (NIO) might influence the climate in the local and surrounding area significantly. The empirical orthogonal function (EOF) was used to analyze the spatiotemporal variation characteristics of SST in the NIO. Simultaneously, seven hydrometeorological elements, including 10-m zonal wind (U10), 10-m meridional wind...
