An increase in the central pressure of a pressure system on a constant-height chart, or an analogous increase in height on a constant-pressure chart; the opposite of deepening. The term is commonly applied to a low rather than to a high. Since filling is almost always accompanied by a decrease in the intensity of cyclonic circulation, it is frequently used to imply the process of cyclolysis. Filling can be defined quantitatively in at least two ways: 1) as the time rate of central-pressure increase; or 2) as that component of the pressure tendency that cannot be attributed to either the motion of the pressure system relative to that point or to the influence of atmospheric tides.
Industry:Weather
An empirical curve relating stream discharge or stage at a point on a stream to discharge or stage at one or more upstream points and, possibly, to other parameters.
Industry:Weather
An equation resulting from the use of finite-difference approximations to the derivatives in an ordinary or partial differential equation. A finite-difference equation may have a solution (or solutions) the behavior of which is quite unlike that (or those) of the differential equation approximated, and care must be taken to exclude or minimize any such solutions in the computation. Finite-difference equations are extensively used in meteorology, a realistic atmosphere usually being described by equations without tabulated solutions. See computational mode.
Industry:Weather
An evaporation pan in which the evaporation is measured from water in a pan floating in a larger body of water.
Industry:Weather
An electron not bound to an atom or molecule. In this sense a (negative) beta particle is a free electron.
Industry:Weather
An arbitrary set of straight lines constructed parallel to the 180° and 0° meridians. They are used for grid navigations; grid north replaces true north.
Industry:Weather
An area of low pressure characterized by uniform barometric pressure without a well- defined horizontal gradient.
Industry:Weather
An area of the ocean where the action of the wind causes waves to be generated. Once generated, the waves generally propagate away from the area. See fetch, swell.
