  2. Atmospheric reanalysis - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_reanalysis

    Operational data analysis. In operational numerical weather prediction, forecast models are used to predict future states of the atmosphere, based on how the climate system evolves with time from an initial state. The initial state provided as input to the forecast must consist of data values for a range of "prognostic" meteorological fields ...

  3. Climate Forecast System (NCEP) - Wikipedia

    en.wikipedia.org/wiki/Climate_forecast_system_(NCEP)

    The Climate Forecast System or coupled forecast system ( CFS) is a medium to long range numerical weather prediction and a climate model run by the National Centers for Environmental Prediction (NCEP) to bridge weather and climate timescales. [1] Version 2 became operational as CFSv2 in 2011.

  4. Numerical weather prediction - Wikipedia

    en.wikipedia.org/wiki/Numerical_weather_prediction

    As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future. The process of entering observation data into the model to generate initial conditions is called initialization.

  5. Weather Research and Forecasting Model - Wikipedia

    en.wikipedia.org/wiki/Weather_Research_and...

    The Weather Research and Forecasting ( WRF) Model [1] ( / ˈwɔːrf /) is a numerical weather prediction (NWP) system designed to serve both atmospheric research and operational forecasting needs. NWP refers to the simulation and prediction of the atmosphere with a computer model, and WRF is a set of software for this.

  6. North American Mesoscale Model - Wikipedia

    en.wikipedia.org/wiki/North_American_Mesoscale_Model

    The North American Mesoscale Model ( NAM) is a numerical weather prediction model run by National Centers for Environmental Prediction for short-term weather forecasting. Currently, the Weather Research and Forecasting Non-hydrostatic Mesoscale Model (WRF-NMM) model system serves as the dynamical core of the NAM model.

  7. Atmospheric model - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_model

    Atmospheric model. A 96-hour forecast of 850 mbar geopotential height and temperature from the Global Forecast System. 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 ...

  8. Parametrization (climate modeling) - Wikipedia

    en.wikipedia.org/wiki/Parametrization_(climate...

    Parametrization (climate modeling) Parameterization in a weather 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 ...

  9. Regional Atmospheric Modeling System - Wikipedia

    en.wikipedia.org/wiki/Regional_Atmospheric...

    Regional Atmospheric Modeling System. The Regional Atmospheric Modeling System ( RAMS) is a set of computer programs that simulate the atmosphere for weather and climate research and for numerical weather prediction (NWP). Other components include a data analysis and a visualization package. [1]
