For example, some air masses are warm and moist, such as those that originate over the subtropical waters of the Gulf of Mexico. Other air masses, such as those that originate over the frigid lands of Arctic Canada, are cold and dry.

Pannus – Ragged-looking accessory clouds that form on the bottom of some clouds during periods of precipitation. Auf Disney+ haben wir den Film „Clouds“ gefunden, der auf einer wahren Begebenheit beruht und ich war einfach unheimlich gerührt. Im Anschluss habe ich etwas nachrecherchiert und es ist unglaublich, was Zach Sobiech der Welt hinterlassen, wie viele Menschen er berührt und sogar deren Leben geändert hat. Deshalb wollte ich unbedingt das Buch „Clouds“ lesen, das seine Mutter geschrieben hat. Erhältlich ist es (bisher) nur auf Englisch. One of the characteristic features of a mature cumulonimbus cloud is an anvil top. Aptly named, anvil tops are long, flat anvil-like protuberances that extend out from the upper portion of the cloud along the tropopause, which is the transition zone between the troposphere and the stratosphere. These clouds often look like a translucent veil that covers much of the sky. In fact, they can cover thousands of miles of the sky in any direction, creating a slight amount of overcast on an otherwise sunny day.However, when accompanied by other favorable atmospheric conditions, this process of surface heating can also lead to severe weather. Indeed, clouds that form during surface heating can eventually become cumulonimbus clouds that lead to isolated thunderstorms on a warm summer’s afternoon. Low Pressure If you have not watched Clouds please, please do so because I think it’s just a beautiful, yes it's a tragic story but I am so thankful it got told in this way. Justins words at the end of the book put it perfectly, he wrote; “My prayer is that you get an opportunity, both through the reading of this beautiful book and the watching of our film based on it - to experience what I will fail to put into words: the magic and inspiration of Zachary David Sobiech”

Up until now, the two different types of cloud formation that we’ve discussed have both had to do with changes in the temperature or pressure of an air parcel. But, the surface of the Earth can also have a major impact on cloud development and on the weather as a whole.

Richard Jones - A Disappointment

As with air that’s heated by the sun, air that’s in a region of low pressure tends to rise up in the atmosphere. Once this air starts rising, it will cool, which will cause the water vapor in this parcel of air to condense into water droplets and form a cloud.

In addition to genera and species, some clouds can be further described by variety. These varieties are somewhat similar to a subspecies when classifying animals and plants. For example, you can have a cirrus fibratus radiatus cloud or an altocumulus lenticularis duplicatus cloud.

A type of arcus cloud, roll clouds are generally associated with the gust front of a thunderstorm. Unlike arcus clouds, however, roll clouds have a very long, tube-like shape. It’s sort of like a mitch-and-match system where you can pair a genus and species name together to create a type of cloud.
