Cumulonimbus (from Latin cumulus, "heaped" and nimbus, "rainstorm") is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. These clouds usually cover the entire sky. Middle clouds (altostratus, altocumulus) reside at an average altitude of ~10,000 feet. 9.

The nimbostratus cloud is a mid-altitude cloud, occurring higher in the atmosphere than stratus clouds do. Common types Of clouds in the troposphere Cumulonimbus from near the round to above 50,080 feet Cirrocumulus (mackeral sky) above 18,000 feet Altostratus clouds are found in the middle cloud level.And unlike their altocumulus counterpart, they're often boring to look at. Precipitation: May produce light showers. Origin: By rise of expanded air layers into higher altitudes. Altostratus clouds are low and gray or white. Low altitude clouds have bases that form 2 km or less above the ground. However, farther down, the ice crystals became more conglomerated.

An altostratus cloud usually forms ahead of storms with continuous rain or snow. Altostratus tends to form ahead of a warm or occluded front, the altostratus gradually thickening into rain bearing nimbostratus. Clouds are simple enough, just a collection of ice crystals or water droplets visible to everyone. Cloud Atlas -> Altostratus. However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto-stratus deck. Altostratus clouds are featureless with little character, so are not classified into 'species' like other cloud types. Cirrostratus clouds indicate upper atmosphere moisture and turbulence, often indicating a change in weather. Cumulus clouds can form at high altitudes, but they usually form closer to the ground and grow vertically. cloud, often evenly and opaquely, which lets the Cirrus clouds are high-altitude clouds formed primarily of ice.

Stratus clouds tend to be featureless, low altitude clouds that cover the sky in a blanket of white or grey. • Formed from altostratus clouds when they collect water. The sizes of the ice crystals in the cloud tended to increase as altitude decreased.
