Remarkable photo shows “mammatus” clouds above Canada, clouds with round bottoms [Amazing Photo of the Day]

When you look up in the sky, what do you see? Clouds, maybe. While it sounds a bit odd because of how we think of clouds as three dimensional figures, the clouds you see in the sky typically have “flat” bottoms. So if normal clouds have flat bottoms, what type of clouds have not-flat (aka round) bottoms? Mammatus clouds. What exactly do mammatus clouds look like? My, I’m glad you asked…

So mammatus clouds are… akin to chickenpox. Just kidding. (And, yes, that is a real photo — not photoshopped, you conspiracy theorists.)

    Cumulonimbus Mammata are typically seen in the vicinity of very severe weather, such as tornadoes, high wind shear, etc. They are an indication of very turbulent activity in the atmosphere. Very impressive sight.

    This particular photo exhibits a much more “regular pattern” than the typical mammata panorama.
