7 European Wind Atlas

8 Wind Atlas for Denmark

9 Regional wind climate of Denmark [ms -1 ] km km Mean wind speed [ms -1 ] at 50 m over z 0 = 0.03 m 5.5

10 Wind Resource Atlas for Denmark Land area of 43,000 km 2 Topographical inputs terrain elevations (5-m) 6 classes of land use terrain roughness map WAsP modelling regional wind climate P-correction factors regular grid ( = 200 m) Database of resources Wind roses for all points Weibull A, k and power density for four heights: 25, 45, 70 and 100 m

11 Wind farm production calculations

12 Wind atlases of the world Wind atlas methodology used by 1500 institutions in more than 100 countries Industry-standard methodology with standard input and output data Complete package for wind resource assessment and micro-siting

13 Numerical wind atlas (KAMM/WAsP) Resource estimation for larger areas taking meso-scale effects (mountains, sea/land breezes etc.) into account Employs a meso-scale model like KAMM (Karlsruhe Atmospheric Mesoscale Model) Input data available over the Internet Met. measurements are not required Super-computer and skilled staff needed! Uncertainty usually larger than wind atlas methodology Output: annual averages of wind speed and power Area: 1000 s of km 2 Resolution: 3-5 km

14 Regional winds from NCEP/NCAR reanalysis

15 KAMM wind resource maps and data Wind speed map [m/s] Power density [W/m 2 ]

16 WAsP- and KAMM-modelled wind climates

17 NCEP/NCAR global reanalysis data Mean wind speed [ms -1 ] Resolution: 2.5 degree (~275 km)

18 GTOPO30 global elevation data Elevations in regular grid Resolution: 30 arc-sec. (~900 m)

19 Shuttle Radar Topography Mission World-wide 30 arc-second resolution (<926 m) Voids interpolated Errors corrected Big voids filled with GTOPO30 data, e.g. western Egypt Sea surface mask: Coastline Extractor

20 Site map from Katamaya, Egypt km with 10-m contours 2 2 km with 1-m contours

21 GLCC global land-use data Eurasia Resolution: 1 km

22 SAR winds over sea Landsat land-use

23 WAsP Engineering Design wind conditions for loads on wind turbines Extreme wind speeds (50-y extreme wind speed) Turbulence (characteristic turbulence intensity) Wind shear and flow angles From seconds (turbulence) to 100 s years (extreme wind) Area: wind farm site
