Evidence for the significant role of sea surface temperature distributions over remote tropical oceans in tropical cyclone intensity

摘要: The role of remote ocean sea surface temperature (SST) in regulating tropical cyclone (TC) characteristics has been examined by performing numerical experiments with a regional scale model. Model simulations have carried out to simulate typhoon Man-yi (July 2007), our case study, under range SST conditions over the Indian Ocean and South China Sea. intensity track systematically changed sensitivity cool warm SSTs that region, following its peak phase. Warm oceans can substantially reduce intensification western North Pacific cyclones, whereas enhance their strength. This is intimately associated enhancement/weakening moisture supply through conveyor belt (MCB) lower troposphere, from Sea into vicinity center. When MCB interrupted occurrences, large-scale transport system significantly reduced, leading weakening eastward shift track. study shows changes also modulate TCs thus help improving forecasting TC intensities tracks.
