A subfield of meteorology generally restricted to that part of meteorology not explicitly devoted to atmospheric motions. There is no real distinction between atmospheric physics and physical meteorology. Physical meteorology usually deals with optical, electrical, acoustic, and thermodynamic phenomena of the troposphere, its chemical composition, the laws of radiation, and the physics of clouds and precipitation.
Industry:Weather
A structure that allows release of excess water from a dam or other hydraulic structure.
Industry:Weather
A strong wind carrying sand through the air. The diameter of most of the particles ranges from 0. 08 to 1 mm. In contrast to a duststorm, the sand particles are mostly confined to the lowest 3. 5 m (10 ft), rarely rise more than 15 m (50 ft) above the ground, and proceed mainly in a series of leaps (saltation). Sandstorms are best developed in desert regions where there is loose sand, often in dunes, without much admixture of dust. Sandstorms are due to strong winds caused or enhanced by surface heating and tend to form during the day and die out at night.
Industry:Weather
A stream that contains water at all times except during extreme drought. Compare ephemeral stream, intermittent stream.
Industry:Weather
A straight line vortex, the flow of which can be modeled in two dimensions, with a point concentration of vorticity surrounded by irrotational flow. See line vortex.
Industry:Weather
A storm characterized by a fall of frozen precipitation in the form of snow.
Industry:Weather
A stochastic process, ''X''(''t''), with properties that do not change over time or space. This means that the marginal distributions of the variate (its mean, variances, and similar characteristics) are time independent. Furthermore, the joint distribution of the values of the process at two (or more) times, ''X''(''t'') and ''X''(''s''), can only depend on the time difference(s), ''t'' − ''s''.
