These crazy-looking clouds recently covered the sky in Saskatchewan. What are they?
These clouds are called mammatus clouds.The rounded and smooth look of mammutus clouds often captivate onlookers. They are often found underneath anvil clouds of severe thunderstorms. Anvil clouds are the flat top of a thunderstorm, or cumulonimbus cloud. It takes a turbulent atmosphere for these clouds to develop. However, mammutus clouds can also form underneath clouds associated with non-severe thunderstorms.
