Tropical cyclone Saudel impact on ocean dynamic over the South China Sea

Abstract

Tropical cyclones (TC) are atmospheric phenomena categorized as extreme weather that is perilous and destructive. The parameters used include sea surface temperature (SST), wind speed (WS), and air pressure (AP), which are factors in the formation of TC. The emergence of TC occurred in October 2020, when it grew in Philippine waters and died out in Vietnamese waters. The characteristics of the waters of the South China Sea (SCS) in particular and the Pacific Ocean in general make them one of the waters with the highest storm potential in the world; therefore, this research was conducted. The purpose of this research is to understand the characteristics of Saudel Cyclone (SC) based on the parameters SST, WS, and AP, which are obtained from the ECMWF website, to be able to describe the process of growth until the extinction of SC. Data from the ECMWF website has limitations because it is model data (re-analysis). The results of this study can determine the process of starting the extinction of SC as well as the characteristics of SST, AP, and WS in the conditions of starting SC, during the peak of SC, and starting the extinction of SC.
