32. Mammatus Clouds
This cloud formation looks like condensation on the ceiling of a greenhouse, or like massive, toxic globules about to rain death on us all. It all matters on your perspective, really, but none can deny that Mammatus clouds are a peculiar sight. Whether you find these gooey clouds calming or unnerving, you are headed for one intense thunderstorm if you happen to spot them!

So, what causes these ripples in the sky? It is turbulence present inside the actual clouds, and maybe some kind of alien technology. Either way, it’s time to head inside and close all the windows. Good luck!
31. Green Flash
Speaking of aliens, this next weather phenomenon is seriously extraterrestrial in appearance. You may (if you were lucky enough) have once spotted a strange, green flash during one particularly odd sunset.
Green Flash
This peculiarity is called a “green flash,” something which relatively few people have ever actually spotted, appearing to be a UFO-like burst of energy. To catch a green flash, you need to look at the sun just as it sets completely, and not a moment sooner or later! We know what you are trying this afternoon.
