{wiki=Category:National_Weather_Service_numerical_models}
The National Weather Service (NWS) utilizes several numerical weather prediction models to forecast the weather. These models use complex mathematical equations to simulate the atmosphere's behavior based on current weather conditions, satellite data, and other observational data. The main functions of these models include: 1. **Data Assimilation**: The models take in vast amounts of observational data from various sources (e.g., satellites, radars, weather stations) to provide an accurate starting point for simulations.
