摘要/Abstract

摘要： 本文利用角动量模式计算获得高风速资料,并通过气象观测站实测资料验证了风速资料的准确性,并将所得风速应用于Jason-1高度计风速反演模式函数研究,得到了一个新的风速反演模式函数。研究结果表明,本文提出的模式函数能更好地反映台风经过时海表面风速情况,实现了高度计对高风速(10~40 m/s)的反演,可作为Jason-1高度计风速反演业务化算法在高风速情况下的补充,以提高高度计风速反演精度。

Abstract: High wind speed data were obtained by using the angular momentum model and their precision was verified by the weather station recorded data. A wind speed inversion algorithm for altimeter was developed by using these wind speeds. The results show that this new algorithm can inverse the sea surface wind speed more accurately when typhoon passes through, which realizes the high wind speed (10~40 m/s) inversion for altimeter. This, therefore, can be taken as the supplement of altimeter wind inversion algorithm for Jason-1 at the high wind speed, and improve the precision of altimeter wind inversion algorithm.

Key words: altimeter, angular momentum model, high wind speed, wind speed inversion algorithm
