摘　　要：Internal solitary waves(ISWs)are common mesoscale dynamic processes in the ocean that are spread throughout the world’s oceans.The South China Sea(SCS),Western Pacific(WPAC)and Indian Ocean(EIND)(SCS-WPACEIND)are areas where ISWs frequently occur.In particular,in the northern part of the South China Sea,Sulu Sea,Celebes Sea,Andaman Sea,Lombok Strait and northeastern part of Taiwan Island,ISWs exist almost year-round.Remote sensing is an important technique to carry out investigations and research on ISWs on a large scale.In particular,optical sensors represented by the Moderate Resolution Imaging Spectroradiometer(MODIS)can observe ISWs for a long time and on a large scale,while SAR sensors such as Sentinel-1 A/B can compensate for the deficiencies in optical sensors and comprehensively observe ISWs.Based on many years of remote sensing surveys of ISWs,this paper uses MODIS and Sentinel-1 satellite remote sensing images of more than 70000 scenes from 2010 to 2020 to carry out survey studies of ISWs in the SCS-WPAC-EIND.The survey systematically gives the temporal and spatial distribution characteristics of ISWs in the SCS-WPAC-EIND and focuses on the analysis of the ISW characteristics in main areas in the SCS-WPAC-EIND,thereby providing basic data for further research on ISWs.
