Strange Holes in Clouds

June 16th, 2010

Under the right atmospheric conditions, an airplane flying through clouds can punch a whole in them, sometimes causing local snowfall. According to Wired Science, “Odd clouds can sometimes elude explanation for decades, and these mysterious gaps in the sky, aptly called hole-punch clouds or channel clouds, have been puzzling sky gazers and scientists alike since the 1940s. A 1968 article in the magazine Weatherwise called them “A Meteorological Whodunit?”

Wired Science continued: “Previous research also suggests that propeller planes could make snow fall when they flew through supercooled clouds, where water droplets remain liquid despite subfreezing temperatures. But until recently, a direct connection between airplanes, hole-punch clouds and snowfall was missing. Now, a team of atmospheric scientists report observing all three in the June Bulletin of the American Meteorological Society.”
