was simulated along with this strong vertical
velocity (Fig. 4). At 2 km ASL, the downdraft in the heavy precipitation region (maximum
velocity -3 m s
-1
) covered a broad area to the northeast of the updraft at 2 km ASL.

as solid contours with a contour interval of 5 m s

contours with a contour interval of 1 m s

. Winds are shown for all grid points where the
vertically integrated mixing ratio of rain exceeded 0.0 kg kg
