Cloud Blog

Mammatus clouds are clouds that carry air filled with ice crystals and rain to the top of the cloud. The cloud then spreads horizontally. The air filled with precipitation is heavier than the surrounding air, so the cloud sinks. Another type of cloud is a Lenticular cloud. Lenticular clouds are clouds that form right angles at high altitudes. When moist air collects around places with high altitude, the side with less wind creates waves of air, making the cloud. Roll clouds form when a downdraft rushes cold air, lifting warm air at a high velocity. Another type of cloud is a Noctilucent cloud. Noctilucent clouds form from water vapor and dust. They form mainly from the contents given off during volcanic activity.
My favorite type of cloud would be the Roll clouds. I think they are quite simple to understand.
