Rainfall regions at the height of 20 m at 11:30 JST (contours) and 12:00 JST (blue regions) reproduced by two NHM-350 ensemble members: a #002 and b #006. The red dots in each panel show where vorticity exceeded 0.1 s−1 at 12:00 JST. The small dots show the trajectories traced backward in time from positions around the southern edge of the northern rainfall region. The colors of the dots indicate the potential temperature at the tracer positions. The black dots on the tracer paths show the tracer positions, from south to north, at 10:30, 11:00, 11:30, and 12:00 JST
