Meteorological Data
To obtain accurate wind speeds, turbulence levels and / or precipitation at a site. RWDI obtains reliable meteorological data through the following methods.
Historical Data
RWDI has access to historical meteorological and topography data for all North American cities and data can also be located for most international locations, everywhere from the Arctic to the Antarctic. RWDI analytically assesses historical data from the closest meteorological stations (and computer simulations of hurricanes or typhoons where applicable) and scales the data to the site using local topography. Data that is scaled include wind speeds, direction and precipitation.
Numerical Simulations
When a long record of reliable surface wind data is hard to come by or too distant from the site, RWDI uses 3-D numerical weather forecast models. For more information, see The latest tool...wind simulations.
More information is available for Bridges.
Full Scale Measurements
If wind speeds and turbulence levels cannot be confidently scaled between the meteorological station and the site, RWDI performs full scale measurements. Wind speed, direction, fundamental turbulence properties such as intensity of turbulence and correlation lengths can be measured.
More information is available for Bridges.
Topographic Model Study
When large-scale terrain exists around the site, RWDI performs a topographic model study in one of our wind tunnels to establish the direction of the wind, the wind speeds and turbulence intensities at the site of interest.
