You’ve seen Canon’s CE-SAT-IE satellite image of Earth, now check out this peculiar lenticular cloud captured by NASA’s *US Geological Survey’s (Thanks JH) Landsat 8 above New Zealand’s South Island. It’s been nicknamed Taieri Pet and was caused by prevailing winds hitting topographic barrier, such as a mountain range.
The wind that is forced to flow up and over the mountains creates a kind of wave in the atmosphere, and in this case, an elongated lenticular cloud. Air basically cools at the crest of the wave, and then causes the water vapor it contains to condense into clouds. You may have seen this type of cloud from the ground, but here’s what one looks like when directly above Earth.
