FromVORTEX FdC
Vortex EXTREMES provides key data on extreme wind speed events to support safer, more cost-effective wind farm design. It allows for statistical calibration with observations to adjust maximum wind speeds. The methodology follows a two-step approach: first, a low-resolution mesoscale simulation identifies 6 major extreme wind events per year over a 30-year period (180 total), enabling fast, affordable candidate selection. Then, WRF-LES is used to simulate these events at high resolution, resolving turbulence and local effects with enhanced accuracy. This process delivers precise estimates of yearly maximum 10-minute wind speeds using one of the most advanced modeling techniques available.Most popular related searches
The calibrated output can be used to derive a better yearly maxima analysis as well as a more accurate Vref estimate.
Vortex EXTREMES delivers a 180-days time series (6 complete days time series per year for each of the last 30 years) at 10-minute temporal resolution generated under WRF-LES technology. The deliverable includes the following variables: wind speed, wind direction, the standard deviation of wind speed and wind direction, 3-second gust, pressure, Richardson number and vertical wind speed. Results are available at any hub height between 50 and 300m above ground.
- Available at any location worldwide, both on and off-shore.
- 10-minute time series simulated at 100 m horizontal resolution using LES technology for the 6 extreme events (24 h) of each year, that means a 180-days time series.
- A report that includes: Gumbel fit, Vref values and yearly maximum wind speeds.
- All heights included from 50 to 300 m.
- Possibility of calibration with observations.
- Hurricane and typhoon report based on storms track data provided by NOAA.
When valuable data on extreme wind speed events, that may affect wind farm design, cost and lifetime, is needed without being only limited to the Vref analysis.
