calculating the wrg and rsf

Hello everyone,

i am quite new using wasp and i was wondering on what basis e.g. the wrg file at mast location is generated. i know what information it contains, but what is of more interest to me is how the A and k values get calculated.

for example, if i have a tab file at mast location and export a wrg also at mast location, does the wrg contain then the A and k values describing the all directional frequency distribution of my tab file?

to get the frequency distributions at the turbine locations WAsP calculates rsf files which are A and k values speeded-up from the wrg A and k ones. My questions is.. how does this speeding up happen? What is the background of the calculation. I assume the orography and roughness are in the equation.

Thank you all!

Best Regards,
Slav

You may want to get your hands on a copy of the European Wind Atlas (Troen and Petersen, 1989). Your questions are too substantial to be answered on a forum post, but they are all addressed in Part 3 of the EWA.
