EXAMPLE 4/4

Night time wet microburst near Eraclea (NE Veneto, NE Italy) on June 24, 2014. The image sequence spans a little under two minutes. The first image (upper left) shows the microburst expanding with a distinct rain foot developed on the left. The left edge of the rain shaft is very sharply defined and slightly convex, indicaing a new pulse descending towards the ground. 24 seconds later (upper right) the rain foot had expanded significantly. By 90 second later (lower left), a very distinct and sharply defined backwards curved rain foot had developed on the right, rapidly expanding outwards by 108 seconds later (lower right).
