The WMO classification of the 10 main groups of clouds, called genera. See cloud classification.
Industry:Weather
At a given level in the atmosphere, any low that is generally characterized by colder air near its center than around its periphery; the opposite of a warm low. A significant case of a cold low is that of a cut-off low, characterized by a completely isolated pool of cold air within its vortex. The cyclonic intensity of a cold low increases with height in accordance with the thermal wind equation.

A balloon designed to float at a constant level of altitude, pressure, density, or entropy. See anchor balloon, super-pressure balloon, tetroon, zero-pressure balloon.

Industry:Weather
At a given level in the atmosphere, any high that is generally characterized by colder air near its center than around its periphery; the opposite of a warm high. The anticyclonic intensity of a cold high decreases with height in accordance with the thermal wind equation. Compare thermal high.

Industry:Weather
Smooth compact rime, usually transparent, fairly amorphous, with a ragged surface, and morphologically resembling glaze. This term has two different major applications. 1) Most commonly, it is used as a synonym for glaze, particularly with respect to aircraft icing. Factors that favor clear ice (or glaze) formation are large drop size, rapid accretion of liquid water, slight supercooling, and slow dissipation of latent heat of fusion. Thus, an aircraft flight through supercooled rain at an air temperature of 0° to −4°C is most conducive to clear icing. This type of icing does not seriously distort airfoil shape, but it does add appreciably to the weight of the craft. 2) The term may also be applied to homogeneous bodies of glacier ice and lake ice. Compare rime ice.
Industry:Weather
The climate of a confined space, such as the inside of a house, barn, greenhouse, or a natural or artificial cave. This term is often replaced by the term microclimate, appropriately modified, for example, house microclimate.
