College of DuPage is a public community college with its main campus in Glen Ellyn, Illinois. [3] The college also owns and operates satellite campuses in Addison, Carol Stream, Naperville and Westmont. [4] [5] With more than 20,000 students, the College of DuPage is the second largest provider of undergraduate education in Illinois, after University of Illinois Urbana-Champaign. [6] The ...
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 ...
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 Rapid Refresh ( RR or RAP) is a numerical weather prediction (NWP) model. The model is designed to provide short-range hourly weather forecasts for North America. The Rapid Refresh was officially made operational on 1 May 2012, replacing the Rapid Update Cycle (RUC). The model also serves as the boundary conditions for the higher-resolution High Resolution Rapid Refresh ( HRRR) model, that ...
The Semi-Lagrangian scheme (SLS) is a numerical method that is widely used in numerical weather prediction models for the integration of the equations governing atmospheric motion. A Lagrangian description of a system (such as the atmosphere) focuses on following individual air parcels along their trajectories as opposed to the Eulerian description, which considers the rate of change of system ...
The MM5 (short for Fifth-Generation Penn State/NCAR Mesoscale Model) is a regional mesoscale model used for creating weather forecasts and climate projections. It is a community model maintained by Penn State University and the National Center for Atmospheric Research. The MM5 is a limited-area, terrain-following sigma coordinate model that is ...
HAFS, which uses weather and climate supercomputers installed in 2022, ran side-by-side existing hurricane models last year. It is expected to supplant current forecast models by the end of the ...
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]
