atmospheric pressure
91pressure jump — pressure jump, a sudden, slight increase in barometric pressure, occurring along an atmospheric front and preceding a tornado or other storm …
92Atmospheric model — A 96 hour forecast of 850 mbar geopotential height and temperature from the Global Forecast System An atmospheric model is a mathematical model constructed around the full set of primitive dynamical equations which govern atmospheric motions. It… …
93Atmospheric thermodynamics — In the physical sciences, atmospheric thermodynamics is the study of heat and energy transformations in the earth’s atmospheric system. Following the fundamental laws of classical thermodynamics, atmospheric thermodynamics studies such phenomena… …
94Atmospheric models — Static atmospheric models describe how the ideal gas properties (namely: pressure, temperature, density, and molecular weight) of an atmosphere change, primarily as a function of altitude. For example, the US Standard Atmosphere is essentially a… …
95Atmospheric escape — There are several different processes that can lead to the escape of a planetary atmosphere. In some cases this can be a very important process; for example, both Venus and Mars have probably lost much of their water due to atmospheric escape… …
96Pressure gradient — In atmospheric sciences (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure changes the most… …
