Abstract
Northwest Pacific Ocean (NWP) is known to be having higher number of tropical cyclones (TC) than all over the world. About 87% of the typhoons occur in the latitudinal belt between 20°N and 20°S and two third of all typhoons occur in the Northern Hemisphere. China is one of the countries suffering from the devastation caused by typhoons along the coast of the NWP and South China Sea (SCS). The intensity variations have been verified with the TCs landfall at China coast and also due to El Nino. It is found that during El Nino years the number of TCs reduced, however the intensity is higher. TCs which are having higher intensity are going to devastate the coastal area by means of heavy rainfall, strong winds, storm surges, etc. Alternative measures to assess hurricane intensity or damage potential include Accumulated Cyclone Energy (ACE) and Hurricane Destructive Potential (HDP). This work details the relation between the disasters occurred at China coast and ACE and HDP of TC landfall over China coast during 1995–2016. The year 2005 experiences higher finance losses due to marine disasters mainly due to TCs and higher ACE and HDP. TCs generated in the SCS doesn’t having much influence on financial losses, however the TCs generated, passing through NWP to SCS are having higher intensity and produce higher losses. The losses due to the passing of TCs over coastal areas of China also found. Further, financial losses over coastal provinces are given separately with respect ACE and HDP.
