Atmospheric model This page was last edited on 21 February 2025, at 03:13 (UTC). Text is available under the Creative Commons Attribution-ShareAlike 4.0 ...
In atmospheric science, an atmospheric model is a mathematical model constructed around the full set of primitive, dynamical equations which govern atmospheric motions. It can supplement these equations with parameterizations for turbulent diffusion, radiation , moist processes ( clouds and precipitation ), heat exchange , soil , vegetation ...
The model's name is derived from the major disaster caused by the accidental release of highly toxic gases that occurred in Seveso, Italy in 1976. SNAP (Norway) – The Severe Nuclear Accident Programme (SNAP) model is a Lagrangian type atmospheric dispersion model specialized on modelling dispersion of radioactive debris.
The Jacchia Reference Atmosphere is a reference atmospheric model that defines values for atmospheric temperature, density, pressure and other properties at altitudes from 90 to 2500 km. Unlike the more common US Standard Atmosphere and related models, the Jacchia model includes latitudinal, seasonal, geomagnetic, and solar effects, but must be ...
Parameterization in an atmospheric model (either weather model or climate model) is a method of replacing processes that are too small-scale or complex to be physically represented in the model by a simplified process. This can be contrasted with other processes—e.g., large-scale flow of the atmosphere—that are explicitly resolved within ...
Atmospheric GCMs (AGCMs) model the atmosphere (and typically contain a land-surface model as well) using imposed sea surface temperatures (SSTs). [5] They may include atmospheric chemistry. AGCMs consist of a dynamical core that integrates the equations of fluid motion, typically for: surface pressure; horizontal components of velocity in layers
NRLMSISE-00 is an empirical, global reference atmospheric model of the Earth from ground to space. [1] It models the temperatures and densities of the atmosphere's components. A primary use of this model is to aid predictions of satellite orbital decay due to atmospheric drag.
