These clouds are also known as billow clouds, shear-gravity clouds, KHI clouds, or Kelvin-Helmholtz billows. The rolling eddies seen at the top of the cloud layers are usually evenly spaced and ... These interesting clouds form when there is instability in the atmosphere and differing densities in the air layers.

Over time, the cloud droplets do eventually evaporate and the mammatus dissolve. ... Billow clouds are created from instability associated with air flows ... They can form wherever stable moist air flows over a mountain creating a ...

Billow clouds of the second kind form from clear air in a group of amplifying waves, ... which could reach the condensation level, and although they do not ...

Billow clouds can form at many different levels in the atmosphere, and are related to wind shear. Here, the stratocumulus undulatus billows were trapped under a temperature inversion in the low levels of the troposphere.

The experiment will use planes to study how clouds form ... They are searching for details of how clouds form and carry heat high up into the atmosphere. ... But there is also uncertainty over how the climate will react, and one of the key issues centres on a poor understanding of what goes on inside clouds - how they form,

More specifically, he is working on (1) the glaciation of convective clouds, (2) the electrification of thunderstorms, (3) the relationships between lightning frequency and other thundercloud parameters, and (4) a possible global warming mitigation technique (please see "Research on Global Warming..." section,

High-Level Clouds; High-level clouds form above 20,000 feet (6,000 meters) and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals. ... Other Cloud Types; Cloud types include: contrails, billow clouds, mammatus, orographic and pileus clouds.

Some clouds are accompanied by precipitation; rain, snow, hail, sleet, even freezing rain. The purpose of this module is to introduce a number of cloud classifications, different types of precipitation, and the mechanisms responsible for producing them.
