Who made a hole in the clouds over Canada?

Several users have posted in social networks photos in which they managed to capture the unusual atmospheric phenomenon in the skies over Chilliwack (Canada). The phenomenon looks like impressive size round holes in the thick layer of clouds.

This strange phenomenon is the result of a combination of low temperature, air movement and atmospheric instability. If you look at a leaky cloud from the bottom up, it seems that part of the cloud falls from the sky. As it turned out, was indeed the case. Middle clouds are formed from liquid droplets at temperatures below 0° degrees Celsius. When through the cloud flies the plane, creates interference that cause freezing. In place drops of water grow ice particles. Eventually the ice crystals in these portions of the cloud become so large that literally falls from the sky.
