Wind Information describes observational and derived data about the motion of air in Earth's atmosphere, including speed, direction, gusts, shear, and temporal variability. It underpins operational activities in aviation, maritime operations, renewable energy planning, and National Weather Service forecasting. Wind records and analyses are maintained and disseminated by institutions such as the World Meteorological Organization, European Centre for Medium-Range Weather Forecasts, and national agencies.
Overview and Definition
Wind information encompasses quantitative and qualitative records produced by instruments and models at scales from local to planetary. Fundamental parameters include wind speed, wind direction, wind shear, turbulence intensity, and gust magnitude as measured at specified heights like 10 meters or turbine hub heights. Definitions and standards are promulgated by organizations such as the International Civil Aviation Organization, American Meteorological Society, and International Electrotechnical Commission to support interoperability among Federal Aviation Administration, Civil Aviation Authority, and energy regulators.
Measurement and Instruments
Observations rely on deployed sensors and platforms including cup anemometers, sonic anemometers, pitot-static systems, Doppler lidar, sodar, and remote-sensing satellites. Key instrument providers and facilities include National Oceanic and Atmospheric Administration field sites, NASA research aircraft campaigns, university observatories like Massachusetts Institute of Technology turbine testbeds, and commercial networks such as those operated by Siemens Gamesa and Vestas Wind Systems. Fixed stations like those in the Automated Surface Observing Systems network complement mobile profilers used by Met Office researchers and military units, while buoy networks managed by the National Data Buoy Center and research vessels from institutions such as Woods Hole Oceanographic Institution provide marine wind data.
Meteorological Factors and Dynamics
Wind dynamics arise from pressure gradients, Coriolis forces, thermal contrasts, and terrain interaction. Synoptic drivers include cyclones and anticyclones analyzed by the European Centre for Medium-Range Weather Forecasts and observed by platforms such as Geostationary Operational Environmental Satellite and METEOSAT. Mesoscale phenomena like sea breezes, mountain waves, and urban canopy flows are studied by centers including Scripps Institution of Oceanography and National Center for Atmospheric Research. Interactions with large-scale oscillations such as the El Niño–Southern Oscillation and the North Atlantic Oscillation modulate regional wind regimes, influencing sectors overseen by agencies like the United States Geological Survey and Energy Information Administration.
Wind Data Sources and Reporting
Primary sources include surface observation networks (e.g., Synoptic Meteorological Observing Network stations), upper-air soundings from radiosonde launches by organizations such as Environment and Climate Change Canada, and satellite-derived wind products from missions like scatterometers on ASCAT and QuikSCAT. Reanalysis datasets produced by National Aeronautics and Space Administration and European Centre for Medium-Range Weather Forecasts integrate historical observations. Reporting standards are codified in manuals by World Meteorological Organization and operational bulletins produced by Federal Aviation Administration flight information services, International Maritime Organization routing advisories, and grid operators like California Independent System Operator.
Applications and Uses
Wind information supports aviation operations managed by International Civil Aviation Organization procedures, maritime routing used by International Maritime Organization guidelines, and energy forecasting by companies such as Ørsted and NextEra Energy. It informs structural design codes issued by institutions like American Society of Civil Engineers and hazard assessments by Federal Emergency Management Agency. Climate research at centers like Potsdam Institute for Climate Impact Research and urban planning studies at universities like University College London rely on historical wind climatologies, while emergency services coordinated with Red Cross chapters use real-time wind reports during severe-weather events.
Forecasting and Modeling
Numerical weather prediction and specialized wind models are developed by agencies such as the European Centre for Medium-Range Weather Forecasts, National Weather Service, and research groups at Massachusetts Institute of Technology and Imperial College London. Models include global general circulation models, mesoscale models like the Weather Research and Forecasting Model and computational fluid dynamics simulations for wind turbine wakes used by National Renewable Energy Laboratory. Data assimilation integrates observations from radiosonde launches, Doppler radar networks, and satellite scatterometers to update forecasts disseminated through services provided by AccuWeather, Météo-France, and national meteorological services.
