The melting of ice due to applied pressure. The melting point of pure ice is lowered 0. 0072 K per atmosphere of applied pressure. Pressure melting is responsible for regelation.
Industry:Weather
The middle portion of the nocturnal atmospheric boundary layer characterized by weak sporadic turbulence and initially uniformly mixed potential temperature and pollutants remaining from the mixed layer of the previous day. Below the statically neutral residual layer is the stable boundary layer in contact with the radiatively cooled ground, and above it is the capping inversion that separates boundary layer air from free-atmosphere air.
Industry:Weather
The mathematical description of a random variable in terms of its admissible values and the probability associated, in an appropriate sense, with each value. The probability distribution of a continuous variate is defined by stating the mathematical equation of the distribution function ''F''(''x'') or the probability density function ''f''(''x'') (if it exists) together with the range over which the equation holds. The probability distribution of a discrete variate is commonly defined by stating the equation for the probability ''p''(''x'') that the variate will assume any particular value ''x'', and indicating what values are possible.
Industry:Weather
The mathematical mean value over multiple points in space. These can be points along a line or path (line average), along a surface (area average), or within a volume (volume average). Compare time average, ensemble average; See'' also'' ergodic condition.
Industry:Weather
The magnitude of a deviation from a statistic that will be exceeded with probability of 0. 50, or on half the occasions. For a normal distribution it is 0. 6745 times the standard deviation. The probable error is not “probable” in any peculiar sense and should have no more significance attached to it than the above.
Industry:Weather
The massless particle that, according to the quantum theory of radiation, carries the smallest discrete amount of electromagnetic energy ''h''ν, where ''h'' is Planck's constant and ν is the frequency of the associated electromagnetic wave. Although the photon has no mass it does have (linear) momentum ''h''ν/''c'', where ''c'' is the free- space speed of light, and intrinsic angular momentum (spin) ''h''/2π, as evidenced by radiation pressure and radiation torque.
Industry:Weather
The major branch of climatology that deals with the explanation of climate, rather than with presentation of it (climatography).
Industry:Weather
The lobe-shaped, expanded, terminal part of a valley glacier spread out over broad lowlands at the base of mountains.
Industry:Weather
The local (Eulerian) rate of change of a quantity with time, ∂/∂''t'', also known as a tendency term. It indicates the increase or decrease in a quantity.
Industry:Weather
The location of a meteorological station from the point of view of geography, orientation, and position of shelter and various instruments to include latitude, longitude, and elevation.
