The causes of encephalopathy are both numerous and varied.

It is often seen 12 to 18 hours in advance of an unsettled weather system. Cirrocumulus clouds look like many small tufts of cotton, rippled sand or even the scales of a fish (hence the term âmackerel skyâ). Middle clouds: Altostratus, altocumulus and nimbostratus clouds are typically found between 6,000 and 20,000 feet above the ground. Altostratus resembles a smooth gray sheet across the sky. Sometimes the sun shines through the layer as a diffuse ball as if you were looking at it through a pane of frosted glass.
Clouds are given different names based on their shape and their height in the sky. Some clouds are near the ground. Others are almost as high as jet planes fly. Some are puffy like cotton. Others are grey and uniform. The diagram below shows where different types of clouds are located in the sky. Visit the Cloud Gallery to see photos of the different cloud types. 1  The highest clouds in the atmosphere are cirrocumulus, cirrus, and cirrostratus. 2  Mid-level clouds include altocumulus and altostratus. 3  The lowest clouds in the atmosphere are stratus, cumulus, and stratocumulus.
