Wind direction reference system

[Lidia]

Hi

I have a very simple question: what reference system does WAsP use for wind direction? I want to use wind data that comes in a u & v component format but I'm not sure of how to meassure the direction of the wind. I always assumed it was 0º for wind coming from the west and 90º for wind coming from the south (like your usual mathematical angles). But then I thought it may use the 'meteorological' angles; 0º for north winds and 90º for east winds (?). Can someone confirm which one is it?

Thank you!!

Hi Lidia

 

WAsP uses geographical north direction. Read more about it at WAsP help, look for "Reference directions".
