利用AMSR-E对台风“泰利”的初步分析

A primary analysis of typhoon Talim by AMSR-E

基于洋面上的微波辐射传输模型,采用多元线性回归算法,建立了海洋-大气参数的反演算式,并对其进行了验证。在此基础上,根据AMSR-E的反演结果,对台风“泰利”的发生发展过程进行了初步分析。结果表明,反演算式的精度接近于网上公布的业务产品,反演结果比较符合实际情况;但是由于受到所采用物理模型的限制,反演结果对于强降水区不敏感。

A retrieval algorithm has been developed by multi-linear regression method based on a microwave radiative transfer model, and a preliminary validation has been implemented. According to the retrieval results by AMSR-E, a primary analysis of typhoon Talim has been done about the course of its occurrence and development. The results indicate that the retrieval results can achieve the precision of the operational product closely and accord with the actual condition in general. But restricted by the microwave radiative transfer model, the retrieval results are insensitive to heavy rain.
