Very cool list with a number of things I was not familiar with including something called gravity waves, which are described thusly:

“In a gravity wave, the upward moving region is the most favorable region for cloud development and the sinking region favorable for clear skies. That is why you may see rows of clouds and clear areas between the rows of clouds. A gravity wave is nothing more than a wave moving through a stable layer of the atmosphere. Thunderstorm updrafts will produce gravity waves as they try to punch into the tropopause. The tropopause represents a region of very stable air. This stable air combined with the upward momentum of a thunderstorm updraft (trigger mechanism) will generate gravity waves within the clouds trying to push into the tropopause.”

Right. Anyway there’s an awesome video of the effect that looks like something that should have been in Koyaanisqatsi. In fact nearly all the phenomena listed have accompanying videos, or at least an image.
