Punching Through

In January 2007, satellites captured an extraordinary example of hole-punch clouds visible over the southern United States. But occurences of the cloud type, albeit usually less pronounced, show up every year over Earth’s mid- and high-latitudes. A more recent display developed over eastern China, visible in this image acquired on December 28, 2016, with the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite.
This strange phenomenon results from a combination of cold temperatures, air traffic, and atmospheric instability. If you were to look from below, it would appear as if part of the cloud was falling out of the sky. As it turns out, that’s actually what’s happening.

Punching the Sky

On January 29, 2007, Terra MODIS acquired this extraordinary example of a phenomenon known as “hole-punch clouds” over Oklahoma, Arkansas, Louisiana, and Texas.
...
The clouds are initially composed of liquid drops at a super-cooled temperature below 0° Celsius. As an airplane passes through a cloud, particles in its exhaust can create a disturbance that triggers freezing. Ice particles then quickly grow at the expense of water droplets. Eventually the ice crystals in these patches of clouds grow large enough that they literally fall out of the sky – earning hole-punch clouds their alternate name: “fallstreak holes.” /Wikipedia link given by the editor/
