middle infrared"The portion of the electromagnetic spectrum lying between the near-infrared and the far infrared. This covers the wavelength range approximately from 4 to 15 μm, but usage varies.
MIDDLE CLOUDS
A term used to signify clouds with bases between 6,000 and 18,000 feet. At the higher altitudes, they may also have some ice crystals, but they are composed mainly of water droplets.

Middle Clouds In the middle family are the altostratus, altocumulus, and nimbostratus clouds. The height of the bases of these clouds ranges from 6,500 to 23,000 feet in middle latitudes.
middle clouds: clouds found between 2-4 kilometers (6500-13000 feet) in polar regions and 2-8 kilometers (6500-25000 feet) in tropical regions. Contains altocumulus and altostratus clouds, and sometimes nimbostratus.

These develop between 6,500 and 16,500 feet (between 2,000 and 5,000 m) and are denoted by the prefix alto-. They are made of water droplets, and are frequently supercooled.

Altocumulus clouds (Ac) Middle clouds consisting of roll-like patches or puffs forming a wavy pattern.
The rippled effect gives the appearance of fish scales.

Altocumulus, altostratus, and nimbostratus are the main types of middle clouds. This altitude applies to the temperate zone. In the polar regions, these clouds may be found at lower altitudes.
Middle clouds form between 6,500 and 20,000 feet and are denoted by the prefix ALTO. They are made of water droplets and include altostratus and altocumulus. Low clouds are found up to 6,500 feet and include the stratocumulus and nimbostratus clouds.
The middle clouds are altocumulus, altostratus, nimbostratus and portions of cumulus and cumulonimbus. The low clouds are stratocumulus, stratus and most cumulus and cumulonimbus bases, and sometimes nimbostratus. 3.
