This study examines the tropical cyclone(TC)landfall activities over the East Asia in three types of decaying phase of warm sea surface temperature anomalies(SSTAs)over the equatorial central-eastern Pacific:eastern Pacific warming decaying to La Nina,eastern Pacific warming decaying to a neutral El Nino-Southern Oscillation phase,and a central Pacific warming decaying year.Results show that,for the type of eastern Pacific warming decaying to La Nina,more TCs make landfall over Hainan Island and Beibu Gulf,whereas fewer TCs reach eastern China coast.In particular,the number of landfalling TCs remarkably decreases in the decaying phase of eastern Pacific El Nino to a neutral year.During the decaying phase of central Pacific El Nino events,more TCs tend to make landfall over southern China,Indochina Peninsula and the Philippines.The anomalies of atmospheric circulation and environmental conditions induced by the SSTAs over the tropical Pacific in the different decaying types are responsible for the evident variation in features of TC landfall.
