图3. 雷达与模式数据EOF椭圆对比图(a)及两者的方向角误差(b)

蓝色为雷达数据, 红色为模式数据, 数据点以经度0.25°、纬度0.15°的间隔绘制; 用“★”标记点A(21°57′N, 113°21′E)和点B(21°48′N, 113°06′E)

Fig. 3. EOF ellipses comparison between radar and model data (a) and their directional angle errors (b). Blue represents radar data, red represents model data, and the data points are plotted at intervals of 0.25° longitude and 0.15° latitude. Points A (21°57′N, 113°21′E) and B (21°48′N, 113°06′E) are marked with “★”
