Dear all,<br><br>I am extracting wind speed at different heights (20m, 50m, 115m, 160m) from the WRF run with NOAA land surface model, YSU pbl scheme using 2 way nesting with 27 and 9 km resolutions. The model is showing good results which agree with hub data but the 9 km results shows more speed of wind as compare to hub data (observed). I wonder what could be the reason that improving the resolution disturbing the wind speed accuracy.<br>
<br>Best regards,<br><br>Amjad.<br>
