The sum of the elevation head and the pressure head. Same as piezometric head.
Industry:Weather
The tangential force at the surface between two liquids, or a liquid and a solid, caused by the difference in attraction between the molecules of each phase. Expressed as a force per unit length or as an energy per unit area.
Industry:Weather
The study of the interaction of substances with infrared electromagnetic radiation in the 3–33-μm spectral region. In this spectral region the infrared (IR) radiation interacts with vibrational–rotational energy levels of the substance under study. IR spectroscopy can be used to determine the concentration of the sample under study or to study the spectral characteristics of the sample. In the former case, the absorption of IR radiation is related to the sample concentration through the Beer–Lambert law. In studying spectral features, one obtains information about functional groups, interatomic distances, bond-force constants, and molecular charge distributions. See tunable laser spectroscopy.
Industry:Weather
The study that deals with the water vapor content (humidity) of the atmosphere.
Industry:Weather
The state of a time-dependent dynamical system, for instance, an NWP model, at a given time used to start a forecast of the future state of the system. See analysis.
Industry:Weather
The state or condition of the ice on a river, lake, or other body of water, caused by the thermodynamics of weather conditions.
Industry:Weather
The study of fluid motion. “Fluid” here refers ambiguously to liquids and gases. Although “classical” hydrodynamics was primarily concerned with incompressible fluids, the term aerodynamics has been reserved for such a specialized aspect of compressible fluid flow that most of meteorological dynamics is best included under the general heading of “hydrodynamics. ” W. And J. Bjerknes refer to the hydrodynamics of compressible fluids as physical hydrodynamics.
Industry:Weather
The standard unit of measurement for frequency in cycles/second. Prefixes include kilo (103), mega (106), and giga (109), abbreviated kHz, MHz, and GHz; replaces cycles per second in modern usage.
Industry:Weather
The study of the annual variation and geographic distribution of precipitation.
