摘    要:针对中国南海ERS-2/SAR三维对流涡旋图像,分别利用Young的协方差方法和惯性子域方法,反演了对流海洋大气边界层高度、海洋大气边界层垂直对流尺度速度、表面浮力通量、Obukhov长度、稳定性校正后的海面风速和海面风速稳定性校正因子。结果表明,2种反演方法的结果符合较好,在一定程度上说明利用协方差方法和惯性子域方法从卫星SAR图像反演海洋大气边界层参数的有效性。

关 键 词:海洋大气边界层  合成孔径雷达(SAR)  反演

Abstract:In this paper, taking aim at the ERS-2/SAR imagery of three-dimensional convective cell over the South China Sea, Young's covariance method and inertial subrange method are used to retrieve the depth of convective marine atmospheric boundary layer(MSBA), the vertical convective scale velocity of MABA, the surface buoyancy flux, Obunhov lenght, the stability corrected surface wind velocity and the stability correction factor for surface wind velocity from the SAR imagery. It is shown from the retrieval results that the retrieval results by using the two methods are consisitent with each other, which indicates that the two method are all valid for retrieving the MABL parameters from satellite-borne SAR imagery.
Keywords:marine atmospheric boundary layer  synthetic aperture radar(SAR)  retrieval
