Influence of Underlying Surface on Distribution of Hourly Heavy Rainfall over the Middle Yangtze River Valley

Figure 10

The diurnal variation (hourly value minus daily average value) of the ageostrophic wind when HHR occurs at sunrise or sunset in each region (Figure 10a-d) and the diurnal variation of the ageostrophic wind on non-HHR days (Figure 10e). The regional average range of Figure 10e is (27°N–32°N, 110°E–118°E), and the regional average range of other figures is marked in the upper right corner. The contour line represents the wind speed, and one bar of wind bar is 1 m/s.
