Today is World Meteorology Day, so we’re high up in the atmosphere, above the clouds, for a satellite view of fallstreak holes. These gaps in the clouds are sometimes called hole-punch clouds. The holes form when supercooled water droplets suddenly freeze—often when a plane flies through the cloud—and then fall, leaving an opening in the formation. Scientists are still gaining new insights on how fallstreak holes form and behave.
What happened to these clouds?
