The Global Forecast System (GFS) is a weather forecasting model developed by the National Oceanic and Atmospheric Administration (NOAA). It uses complex mathematical equations to simulate the atmosphere and predict weather patterns globally. The GFS provides forecasts for various time frames, ranging from a few hours to several days ahead. The model incorporates data from satellites, weather stations, and buoys to improve accuracy. It generates forecasts for temperature, precipitation, wind, and other meteorological elements. The GFS is widely used by meteorologists and researchers to understand and predict weather events, contributing to public safety and planning.
