Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
The technique of measuring radiant energy, especially radiant energy in that portion of the total electromagnetic spectrum lying adjacent to the visible region. Radiometry is to be distinguished from the closely related subject of photometry, the latter being specifically concerned with the quantitative response to visible radiation of the human eye. See actinometer.
Industry:Weather
The temperature of the ocean surface. The term sea surface temperature is generally meant to be representative of the upper few meters of the ocean as opposed to the skin temperature, which is the temperature of the upper few centimeters.
Industry:Weather
The temperature of the air just above the runway at an airport (usually at about 4 ft but ideally at engine and/or wing height), used in the determination of density altitude. Therefore, runway temperature observations are made and reported at airports when critical values of density altitude prevail.
Industry:Weather
The systematic derivation of linearized equations of systems by the method of small perturbations, exhibiting the assumptions involved; or any model derived by use of this method.
Industry:Weather
The taking up of one substance by another, either absorption or adsorption.
Industry:Weather
The sum of the static head plus friction, as well as all other head losses on a pump, for a given discharge.
Industry:Weather
The systematic analysis of random phenomena. Primarily, it is the application of probability theory to specific data, but includes special techniques and principles not subsumed under probability. Statistics is concerned with collecting and processing data, summarizing information, estimating descriptive constants (parameters), discovering empirical laws, testing hypotheses, and designing experiments in such a way that valid inferences can be drawn from empirical evidence.
Industry:Weather
The symmetry of a configuration the properties of which are functions only of radial distance from an origin, and thus independent of the azimuthal coordinate in two dimensions and of azimuthal and latitudinal coordinates in three dimensions. Radial symmetry in two dimensions is often called circular symmetry; in three dimensions, spherical symmetry.
Industry:Weather
The summer phase of the annual cycle of winds driven by the land–sea thermal contrast. The heating of the landmasses during summer leads to a deficit of atmospheric pressure over the continents, resulting in an onshore flow. Other factors such as the topography of the land have a considerable effect. The summer monsoon is strongest on the southern and eastern sides of Asia, but it can also occur over northern Australia, parts of Africa, the southwestern United States, and the Mediterranean. See monsoon; Compare winter monsoon.
