The American Meteorological Society promotes the development and dissemination of information and education on the atmospheric and related oceanic and hydrologic sciences and the advancement of their professional applications. Founded in 1919, AMS has a membership of more than 14,000 professionals, ...
The use of multiple transmitter frequencies on successive pulses in a radar system to reduce the variance of a measurement by taking advantage of the greater statistical independence of measurements made at different frequencies.
Industry:Weather
The use of real-time precipitation and streamflow data in rainfall-runoff and streamflow routing models to forecast flow rates and water levels for periods ranging from a few hours to days ahead, depending on the size of the watershed or river basin.
Industry:Weather
The vertical component of the vector equation of motion in natural coordinates when the acceleration of gravity is replaced by the virtual gravity. For most purposes it is identical to the hydrostatic equation.
Industry:Weather
The transport of atmospheric properties by and in the direction of the geostrophic wind.
Industry:Weather
The upper surface of a layer of liquid at which the pressure on the liquid is equal to the external atmospheric pressure, assumed constant. The existence of a free surface is expressed, in hydrodynamics, by the relation Dp/Dt = 0 on the free surface, where p is the total fluid pressure; this relation is often referred to as the free- surface condition and is a special case of a dynamic boundary condition.
Industry:Weather
The transmission function that results when specific band models are adapted to more general situations. They provide a wavelength-integrated transmission function over part or all of the band.
Industry:Weather
The transport (flux) of an atmospheric property by means of the geostrophic wind. When applied to the horizontal average flux by an eddy, the geostrophic flux of geostrophic momentum will be zero unless the eddy has horizontal axis tilts.
Industry:Weather
The transport of an atmospheric quantity into or out of the ground. The most common example is the transport of sensible heat into the ground due to radiative heating of the ground surface.
Industry:Weather
The transitory vector departure, lasting for a fairly short time, of the wind velocity from its mean value.
