Fig. 5From: Precipitation estimation performance by Global Satellite Mapping and its dependence on wind over northern VietnamHorizontal distribution of GSMaP performance for the period May–Aug., in 2000–2010. GV ratios in a northerly, b easterly, c southerly, and d westerly 850 hPa wind cases, at Hanoi, are shown with contours (interval 0.2). The wind direction range in panels a, b, c, and d are 315−360∘ and 0−45∘,45−135∘,135−225∘,and225−315∘, respectively. e The difference between d and c, with contours (interval 0.2). Broken and solid lines show negative and positive values, starting at values of ?0.1 and 0.1, respectively. The regions outside the quadrilateral region enclosed by the four Hanoi area radiosonde stations (Vinh, Bach Long Vi, Dien Bien Phu, and Nanning, see Table 2) are shown with paler colors. The four stations show higher correspondence in their zonal wind components with Hanoi, as summarized in Table 2. The horizontal resolution is 0.1 degreeBack to article page
