RISK ASSESSMENT AND REGIONALIZATION OF TROPICAL CYCLONE DISASTER OVER CHINA'S SURROUNDING SEA
In order to understand the variation trends and disaster risk of tropical cyclone in the background of climate change, we investigated the the characteristics of intensity and frequency of tropical cyclones over China's surrounding sea. From the point of view of risk analysis, we considered a conceptual framework of tropical cyclone disaster risk and developed an index system and assessment model. The risk regionalization of tropical cyclone disaster in China's surrounding sea is carried out through GIS technology. The results show that the frequency and the extreme peak wind-speed of tropical cyclones were slightly declined during the last 60 years when the typhoon and strong wind were rising significantly in the recent 10 years. The most risky areas caused by tropical cyclone disaster include the north part of South China Sea and the eastern Philippine Sea.
