21Large eddy simulation — (LES) is a numerical technique used to solve the partial differential equations governing turbulent fluid flow.It was formulated in the late 1960s and became popular in the later years.It was first used by Joseph Smagorinsky to simulate… …
22Convective available potential energy — A skew T plot showing a morning sounding with a large hydrolapse followed by an afternoon sounding showing the cooling which occurred in the mid levels resulting in an unstable atmosphere as surface parcels have now become negatively buoyant. The …
23Atmospheric dispersion modeling — Industrial air pollution source Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms… …
24Glossary of environmental science — This is a glossary of environmental science.Environmental science is the study of interactions among physical, chemical, and biological components of the environment. Environmental science provides an integrated, quantitative, and… …
25Log wind profile — The Log wind profile is a semi empirical relationship used to describe the vertical distribution of horizontal wind speeds above the ground within the atmospheric surface layer. The relationship is well described in the planetary boundary layer… …
26Precipitation (meteorology) — Long term mean precipitation by month In meteorology, precipitation (also known as one of the classes of hydrometeors, which are atmospheric water phenomena is any product of the condensation of atmospheric water vapor that falls under… …
27Balanced flow — In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected… …
28Microburst — Illustration of a microburst. Note the downward motion of the air until it hits ground level. It then spreads outward in all directions. The wind regime in a microburst is opposite to that of a tornado …
29Outline of earth science — See also: Index of earth science articles The following outline is provided as an overview of and topical guide to earth science: Earth science – all embracing term for the sciences related to the planet Earth.[1] It is also known as geoscience,… …
30Troposphere — The troposphere is the lowest portion of Earth s atmosphere. It contains approximately 75% of the atmosphere s mass and almost all of its water vapor and aerosols. The average depth of the troposphere is about 11 km (7 miles) in the middle… …
