1Atmospheric pressure — Air pressure redirects here. For the pressure of air in other systems, see pressure. Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth s atmosphere. In most… …
2Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …
3Atmospheric circulation — is the large scale movement of air, and the means (together with the smaller ocean circulation) by which heat is distributed on the surface of the Earth. The large scale structure of the atmospheric circulation varies from year to year, but the… …
4Low-pressure area — This depiction of the Hadley cell shows the process which sustains low pressure areas. Diverging winds aloft allow for lower pressure and convergence at the Earth s surface, which leads to upward motion. A low pressure area, or low , is a region… …
5Low pressure area — A low pressure area, or low , is a region where the atmospheric pressure is lower in relation to the surrounding area. Tropical storms, extratropical cyclones, subpolar cyclones, and subarctic cyclones are called low pressure cells.Lows are… …
6weather map — a map or chart showing weather conditions over a wide area at a particular time, compiled from simultaneous observations at different places. [1870 75, Amer.] * * * ▪ meteorology any map or chart that shows the meteorological elements at a given …
7manifold pressure — The absolute pressure in the intake manifold of a reciprocating engine. It is the pressure at which the fuel air mixture is forced into cylinders and is equal to the atmospheric pressure plus a boost less friction losses in the manifold less the… …
8climatic map — chart that shows the geographic distribution of the monthly or annual average values of climatic variables i.e., temperature, precipitation, relative humidity, percentage of possible sunshine, insolation, cloud cover, wind speed and… …
9Weather map — A surface weather analysis for the United States on October 21, 2006. A weather map displays various meteorological features across a particular area at a particular point in time.[1] Such maps have been in use since the mid 19th century and are… …
10National Atmospheric Release Advisory Center — The National Atmospheric Release Advisory Center (NARAC) is located at the University of California s Lawrence Livermore National Laboratory. It is a national support and resource center for planning, real time assessment, emergency response, and …
