介绍了一种利用星载合成孔径雷达（SAR）数据确定热带气旋中心的客观方法，该方法基于SAR图像中清晰的热带气旋眼结构。一系列雷达卫星-1合成孔径雷达图像，它捕捉了2001年至2007年期间在世界海洋盆地的TC。此外，还将使用最先进的大气数值模型，介绍一个案例研究，研究在热带气旋通过期间在Sentinel-1A合成孔径雷达图像上观测到的千岛群岛上空的大气重力波。其目的是获得更完整的了解的产生机制和动力学的重力波。
This chapter introduces an objective method for determining the center of the tropical cyclone (TC) from spaceborne synthetic aperture radar (SAR) data based on the structures of the well-defined TC eyes in the SAR images. A series of Radarsat-1 SAR images are used, which capture the TCs over the world ocean basins during the years from 2001 to 2007. Also, a case study of the atmospheric gravity waves over the Kuril Islands observed in a Sentinel-1A SAR image during the passage of an extratropical cyclone will be presented together with the use of the state-of-the-art atmospheric numerical model. The objective is to obtain a more complete understanding of the generation mechanism and the dynamics governing the gravity waves.
