Satellite Remote Sensing of Sea Surface Winds: Technique Status and Application Progress

在常规观测资料稀少的洋面上,利用卫星遥感海面风对数值预报模式初始场的构建、海上天气预报精度的提高等具有重要意义。对目前国内外在轨的卫星遥感海面风的各种微波传感器及产品特性做了较全面的评述,并对比了主被动方式遥感海面风产品的异同。结合近年来卫星海面风反演技术的提高,总结了卫星遥感海面风产品在数值天气预报同化、台风强度及路径预报改善和气候研究等方面的贡献,同时展望了卫星遥感海面风技术及其资料在实际应用中的限制和有待进一步研究的内容。

Satellite measurement of sea surface winds （SSW） is important in creating the frst feld of numerical weather prediction （NWP） and improving the marine forecasting accuracy. This paper reviews the international and domestic satellite SSW measurement missions, and tells the main differences of measured SSW products between the intensive and passive ways. It also describes the contributions of satellite derived SSW products to the NWP data assimilation, forecasting the intensity and path of tropical cyclone, and to climate research. In addition, the restriction in SSW products applications and the direction of further study are discussed here.
