%X As the largest source of momentum for the ocean surface, wind affects the full range of oceanic motion and plays a very important part in air-sea interaction. It is recognized that remote sensing (RS) satellite has the capability of acquiring high quality marine winds with fine resolution in both space and time. Meanwhile, geographical information system(GIS) is becoming an unprecedented powerful tool for storing, processing, analyzing, and visualizing geo-spatial data. Jointly using RS and GIS technologies, a marine GIS(MGIS) system based on satellite data is developed for the analysis of global sea surface wind speed. TOPEX altimeter data between January 1993 and December 1998 which cover the oceanic areas within±65°are used as input. An analytical model ofwind speed is proposed, on the basis ofwhich seasonal,annual and interannual variabilities (both intensity and timing) are derived. TheMGIS consists of five function- al modules: A database construction module, a human-computer interface module, a wind speed data preparation and analysis module, a graphic and image production module and a typical illustration management module. The system also includes three data files of model coefficient, coastal line, and typical graphics and images, respectively. A relational database structure is adopted by the system. As examples of the application of thisMGIS, results of three thematic cases are presented, namely, the global marine wind climatology, the Asian Monsoon, and the El Ni o related interannual wind variability. These applications demonstrate the advantages of jointly usingRS and GIS in oceanographic studies. We will continue to improve thisMGIS by expanding its functionality and incorporating other key geophysical parameters into the system.
