(Also called departure. ) In statistics, the difference between two numbers. It is commonly applied to the difference of a variable from its mean, or to the difference of an observed value from a theoretical value. See standard deviation, geostrophic departure.
Industry:Weather
The process of intensification of an atmospheric disturbance, most commonly applied to cyclones and anticyclones. From the dynamical viewpoint, development usually implies the generation of vorticity in the atmosphere due to the action of the baroclinic structure of the flow or to the addition of energy to the disturbance, as distinct from the barotropic redistribution of vorticity.
Industry:Weather
Nucleus of heavy hydrogen (deuterium); atomic particle consisting of one proton and one neutron.
Industry:Weather
Isotope of hydrogen, having one proton and one neutron in the nucleus; heavy hydrogen. Deuterium is a nonradioactive form of hydrogen, occurring naturally with an abundance of about 0. 016%. Deuterium is widely used in spectroscopic and kinetic studies, since the large relative mass difference from hydrogen can lead to very different chemical and physical properties of the compounds in which it is contained.
Industry:Weather
To remove any background linear variation in a time series of data by first computing a linear regression (such as least squares best fit) to the data, and then subtracting it from the data. This aspect of conditioning data helps to remove red noise associated with a long-wavelength or long-period signal that is inadequately sampled because it is longer than the total data period of sampling.
Industry:Weather
The transfer of air from an organized air current to the surrounding atmosphere; the opposite of entrainment.
Industry:Weather
Analysis of hydrological processes using deterministic approaches, in which the hydrological parameters are based on physical relations of the various components of the hydrologic cycle. Deterministic approaches do not consider randomness, so that a given input always produces the same output.
Industry:Weather
Governed by and predictable in terms of definite laws, such as dynamic equations. Compare nondeterministic.
Industry:Weather
Water retained during a flood to be gradually released later at a slower rate.
Industry:Weather
1. The identification, at a stated level of probability, of the presence of a signal or phenomenon with certain characteristics. Less formally, a signal may be said to be detectable if it is observable under ordinary circumstances. 2. In radio, radar, and lidar, the conversion of a radio frequency or light signal to an IF signal, or an IF signal to a video signal, accomplished in a detector or mixer.
