Tropical cyclone (TC) causes huge damage to lives and properties due to strong winds, storm surge, heavy rainfall and flooding (Peduzzi et al., 2012; Zhang et al., 2009). Climate model simulations suggested that the frequency of TCs might increase during the 21st century, especially over the west North Pacific (Emanuel, 2013). Climate changes tend to double the economic damages caused by natural disaster, i.e., strong TCs. East Asia hit by TCs may suffer great damages in the future (Mendelsohn et al., 2012). As estimated by previous studies, the TCs that landed in China caused about 28.7 billion RMB (estimated in 2006) in direct economic loss and 472 deaths per year during 1983–2006 (Zhang et al., 2009). The losses caused by the landfalling cyclones are closely related to their paths and intensities.
