摘要

本研究應用衛星微波遙測之技術與理論從事海面風速之估計。以臺灣四周海域為研究對象，使用被動式微波裝置SSM/I(Special Sensor Microwave / Imager)所收集之微波量測值（亮度溫度），嘗試以Schluessel and Luthardt (1991)所發展的線性風速演算法與Wentz (1992)所發展的疊代風速演算法估計區域性海域之海面風速，期能為臺灣之海象測報作業提供一種異於傳統量測之方法。

This study applies the technique and theory of satellite microwave remote sensing to determine the sea surface wind speed. The seas surrounding Taiwan will be an object of study. The microwave measurements (brightness temperature) were collected by the passive microwave instrument SSM/I (Special Sensor Microwave/Imager). The linear algorithm developed by Schluessel and Luthardt (1991) and the iterative algorithm developed by Wentz (1992) were used to estimate sea surface wind speed of local seas. The goals of this study are expected to supply a way to obtain sea-weather measurements that different from the traditional technique for Taiwan.
