<div dir="ltr">Dear sir<br> I've one doubt regarding wind speed calculation in WRF-ARW model output by using GrADS. I'm using WRF-ARW model since last 2-3yrs for my PhD pupose. Always it one doubt in my mind regading the calculation of wind speed and wind direction in model output through GrADS. <br>
1- Suppose history interval was set in my model run as 1hr,and after postprocessing i want to know the wind speed at t=12th hour of forecast. So how it gives the value? Is it gives the instant wind speed value at that time or the average wind speed of some past time? Because after my model comparison with observation , I found that the observation wind speed and model wind speed has a huge gap.<br>
