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 ...
The K-Index or George's Index is a measure of thunderstorm potential in meteorology. According to the National Weather Service, the index harnesses measurements such as "vertical temperature lapse rate, moisture content of the lower atmosphere, and the vertical extent of the moist layer." [1] It was developed by the American meteorologist ...
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. The WRF replaced the Eta ...
Rapid Update Cycle. Graphical 12-hour forecast output from RUC2. The Rapid Update Cycle ( RUC) was an American atmospheric prediction system that consisted primarily of a numerical forecast model and an analysis system to initialize the model. The first operational implementation was created in 1994, with 60km resolution and a 3-hour cycle.
TORCON uses a 0-10 scale to indicate how likely a tornado is within 50 miles of a given location, according to Weather Station Advisor. A TORCON level of 2 would mean a 20% risk of a tornado ...
