- 摘要:
- 大气运动矢量(AMVs)又称为云导风或云迹风,对全球的数值天气预报有积极的影响。风云四号系列卫星作为中国新一代静止轨道气象卫星,其功能和性能比第一代卫星有大幅提升。为研究风云四号卫星云导风产品同化对台风预报的影响,同时对比新旧两代风云系列静止卫星反演产品之间的差异,分别对风云二号G星和风云四号A星的大气运动矢量反演产品进行数据质量评估和同化预报实验。研究结果表明,风云四号A星的云导风数据质量略优于风云二号G星,同化两颗卫星大气运动矢量产品均对台风预报具有正面的影响,同时同化两颗静止卫星的大气运动矢量产品可以带来更多的积极影响,这一结果对AMVs的后续应用是相当鼓舞人心的。
- Abstract:
- Atmospheric motion vectors(AMVs), known as cloud track winds, have positive impacts on global numerical weather forecasts(NWP). AMVs retrieved from Fengyun2G and Fengyun4A are compared in their data quality and impacts on the typhoon forecasts in order to investigate the differences between the first and second generation of the geostationary meteorological satellites of China. Then conducted data evaluation and assimilation-forecasting experiments on FY2G and FY4A atmospheric motion vectors(AMVs), respectively. The results show that the AMVs data of FY4A show better performance than those of FY2G and assimilating the AMVs of FY2G and FY4A has positive impacts on typhoon forecasts, which is quite encouraging for operational use in the future.
