Hail: hailstones may fall from this cloud if it is a highly unstable environment (which favours a more vigorous storm updraft). Heavy rain: this cloud may drop several inches (centimetres) of rain in a short amount of time. This can cause flash flooding. Strong wind: gale-force winds from a downburst may occur under this cloud.
Altostratus translucidus (V-49) near top of photo thickening into altostratus opacus (V-50) near bottom. Abbreviation: As [9] Stratiform clouds of the genus altostratus form when a large convectively stable air mass is lifted to condensation in the middle level of the troposphere, usually along a frontal system. Altostratus can bring light rain ...
Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.
In any cloud, once enough droplets merge, they become heavy and fall to the Earth as rain or snow. Natural tiny particles, like dust and dirt, typically serve as the driving force for clouds to ...
Cloud seeding can be done by ground generators or planes [citation needed] This image explaining cloud seeding shows a substance – either silver iodide or dry ice – being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation upon the ...
A nimbostratus cloud is a multilevel, amorphous, nearly uniform, and often dark-grey cloud that usually produces continuous rain, snow, or sleet, but no lightning or thunder. [ 1 ] [ 2 ] [ 3 ] Although it is usually a low-based stratiform cloud, it actually forms most commonly in the middle level of the troposphere and then spreads vertically ...
Stratus nebulosus clouds appear as a featureless or nebulous veil or layer of stratus clouds with no distinctive features or structure. [6] They are found at low altitudes, and are a good sign of atmospheric stability, which indicates continuous stable weather. Stratus nebulosus may produce light rain and drizzle or flakes of snow.
A significant winter storm is traveling coast to coast, producing heavy snow, ice, and severe thunderstorms. More than 60 million people are expected to feel the impacts through Monday evening.
