The Aviation Weather Center (AWC) is a critical component of the National Weather Service (NWS), providing timely and accurate weather forecasts, warnings, and advisories to the aviation community. Located in Kansas City, Missouri, the AWC is responsible for issuing forecasts and warnings for the entire United States, as well as parts of the Atlantic and Pacific Oceans. The center's primary mission is to ensure the safe and efficient operation of the national airspace system by providing high-quality weather forecasts and warnings to pilots, air traffic controllers, and other aviation stakeholders.
Organization and Structure
The Aviation Weather Center is organized into several key branches, each with its own specific responsibilities. The Forecast Branch is responsible for issuing forecasts and warnings for the entire United States, while the Warning Branch focuses on issuing warnings and advisories for hazardous weather conditions such as thunderstorms, turbulence, and icing. The Research and Development Branch works to improve the accuracy and effectiveness of AWC’s forecasting tools and techniques, while the Training Branch provides training and support to AWC staff and other aviation weather forecasters. The AWC also works closely with other NWS offices, as well as international weather organizations, to ensure a coordinated and seamless approach to aviation weather forecasting.
Forecasting Tools and Techniques
The Aviation Weather Center uses a variety of sophisticated forecasting tools and techniques to issue accurate and reliable weather forecasts. These tools include computer models such as the Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF) model, as well as satellite imagery and radar data. The AWC also uses nowcasting techniques, which involve analyzing current weather conditions and trends to predict the development of hazardous weather conditions over the next few hours. Additionally, the AWC uses ensemble forecasting, which involves running multiple computer models with slightly different initial conditions to generate a range of possible forecast outcomes.
| Forecast Tool | Description |
|---|---|
| Global Forecast System (GFS) | A global computer model that provides forecast data out to 16 days |
| European Centre for Medium-Range Weather Forecasts (ECMWF) model | A global computer model that provides forecast data out to 10 days |
| Satellite Imagery | Visible and infrared satellite images used to analyze cloud patterns and track weather systems |
| Radar Data | Ground-based and airborne radar data used to detect precipitation and other hazardous weather conditions |
Products and Services
The Aviation Weather Center provides a wide range of products and services to the aviation community, including text forecasts, graphical forecasts, and warnings and advisories. The AWC also issues Airmen’s Meteorological Information (METAR) reports, which provide current weather conditions at airports and other locations. Additionally, the AWC provides Terminal Aerodrome Forecasts (TAF), which provide forecasted weather conditions at airports over the next 24-30 hours. The AWC also offers forecast briefings and consultations to aviation stakeholders, providing tailored weather support to meet their specific needs.
Warning and Advisory Systems
The Aviation Weather Center has a range of warning and advisory systems in place to alert aviation stakeholders to hazardous weather conditions. These systems include the Severe Weather Alert System, which provides alerts for severe thunderstorms, tornadoes, and other hazardous weather conditions. The AWC also uses the Graphical Forecast for Aviation (GFA) system, which provides graphical forecasts of weather conditions, including turbulence, icing, and thunderstorms. Additionally, the AWC issues SIGMET (Significant Meteorological Information) advisories, which provide information on hazardous weather conditions such as turbulence, mountain waves, and volcanic ash.
