Numerical weather prediction ( NWP) uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results. A number of global and regional forecast models are run in different countries ...
The history of numerical weather prediction considers how current weather conditions as input into mathematical models of the atmosphere and oceans to predict the weather and future sea state (the process of numerical weather prediction) has changed over the years. Though first attempted manually in the 1920s, it was not until the advent of the computer and computer simulation that computation ...
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 – that is, those fields which determine the future evolution of the model ...
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]
CAPS also is leading an NSF Large Information Technology Research (ITR) grant that seeks to develop an infrastructure for mesoscale meteorology research and education. Known as Linked Environments for Atmospheric Discovery (LEAD), a transforming element of this project is the ability for analysis tools, forecast models, and data repositories to function as dynamically adaptive, on-demand ...
The Navy Operational Global Atmospheric Prediction System ( NOGAPS) is a global numerical weather prediction computer model run by the United States Navy 's Fleet Numerical Meteorology and Oceanography Center. This mathematical model was run four times a day and produced weather forecasts. The NOGAPS was replaced by the NAVGEM in February 2013.
The Unified Model is a numerical weather prediction and climate modeling software suite originally developed by the United Kingdom Met Office, [1] [2] and now both used and further developed by many weather-forecasting agencies around the world. [3] The Unified Model gets its name because a single model is used across a range of both timescales (nowcasting to centennial) and spatial scales ...
Once calculated manually based mainly upon changes in barometric pressure, current weather conditions, and sky conditions or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account. [1] Human input is still required to pick the best possible model to base the forecast upon, which involves pattern recognition skills, teleconnections ...
