Waterspouts are tornadoes that form over water but, unlike tornadoes, they are usually relatively weak and dissipate once they near or reach land.
“The perfect conditions for waterspouts are instability (cool air over warmer water) and source of spin – or, what we call in meteorology, vorticity,” said director of the International Centre Waterspout Research Wade Szilagy. “You need a combination of the two.”
Because of their relatively non-violent nature, waterspouts are one of the more photogenic and awe-inspiring feats of nature. This year, it seems our weather.com photo fan inbox is overflowing with waterspout photos.
“For North America, for the Great Lakes, waterspout season begins in July and last until late summer or early fall,” said Szilagy. “But waterspouts can happen during the day or night and anytime during the year.”
