The Effect of Tropical Cyclones on Extreme Weather and The Raising of Wave Height in the Southern Region of Indonesia to Espouse Sea Transportation Safety and Maritime Security

Tropical cyclone cases can cause dangerous impacts on the maritime world, consequently, it is necessary to study the effects of extreme weather and also the raising wave height in the tropical cyclone area. This study aims to analyze the characteristics of tropical cyclones and their effect on extreme weather and sea wave conditions so that they can improve maritime safety and security better. The research method used in this study was descriptive quantitative by using data on 3 tropical cyclone cases from 2019 to 2021 within Indonesia's area of responsibility and using the “Ina-wave” model and “Himawari-8 satellite” data. The results of data processing presented that cyclone cases occurred in April and May and had maximum wind speeds ranging from 33 knots to 63 knots, those had been seen from the wave height that experienced a significant raising in the area around the occurrence of tropical cyclones, and experienced the raising in rainfall starting from 3 days before a tropical cyclone grew. It is hoped that this analysis of tropical cyclone cases can increase the awareness for parties of previous activities so that maritime safety and security can be safely maintained by knowing the characteristics of cyclones
