Explaining the “Hole in the Cloud.” - http://mikealger.net/2015/03/18/explaining-the-hole-in-the-cloud/

In a Sierra Wave cloud (a standing lenticular cloud) the center of the top of the cloud is its highest (and therefore its coldest) point. In this case, I think there was enough moisture so that the very top of the cloud began producing precipitation, which caused downdrafts, creating warming and drying where you see it in the picture. It’s a “mesohigh” similar to the feature you get in the eye of a hurricane, or sometimes under a thunderstorm downflow.

Net Zero means we are paying for the destruction of our economy and society in pursuit of an unachievable and pointless policy.
