Analysis and application of spatiotemporal variation in sea surface temperature in the Taiwan Strait based on Himawari-8 data
The Taiwan Strait holds a significant strategic position and great value for research.Investigating the spatiotemporal variations in sea surface temperature(SST)in the Taiwan Strait and its surrounding sea areas helps enhance the understanding of the marine-continental environmental interactions and changes in ocean currents in this region.Such investigation is particularly significant for comprehensively understanding the complex marine frontal systems within the Taiwan Strait.This study investigated the Taiwan Strait and its surrounding sea areas.Using 2016-2020 Himawari-8 satellite data,this study determined the annual,seasonal,and ten-day averages of SST remote sensing data.Based on these data,this study examined spatiotemporal variations in the SST and,accordingly,explored correlations between SST and inland precipitation and coastal fog in Fujian.The results indicate that the annual mean SST in the Taiwan Strait and surrounding sea areas exhibited a zonal distribution,increasing gradually from northwest to southeast.Seasonally,the SST exhibited two distribution patterns:a winter pattern,with isotherms approximately parallel to the coast,and a summer pattern,with isotherms more uniformly distributed.The ten-day SST data allowed for more fine-scale characterization of the spatiotemporal variations in the SST of the Taiwan Strait.The inland monthly precipitation generally exhibited a weak negative correlation with monthly mean SST,with this correlation strengthening with an increase in the distance from open sea areas.Additionally,a strong negative correlation was observed between the SST and coastal fog,with the coastal fog occurrence number trending downward with increasing SST.
