<p class="MsoNormal" style="margin-bottom:12.0pt">Hi users!</p>
</div>
<p class="MsoNormal">I'm running WRF so many time ago for daily forecasts.</p>
</div>
<p class="MsoNormal">In my case, the most important variable is the wind: magnitude and direction.</p>
</div>
</div>
<p class="MsoNormal"><span lang="EN"><br>
The shape of the curve of the diurnal cycle of the wind is OK</span>, but there is a little problem.<br>
<br>
The magnitude of the wind during the diurnal period is OK, but during the night cycle is always overestimated.<br>
In my domain, historically the high maqnitudes of the day are in the afternoon-evening, but the model shows the high magnitudes of the day in the morning-noon<br clear="all">

<div>
<div>

<div>
<div>
<p class="MsoNormal">What can be the problem?</p>
</div>
<div>
<p class="MsoNormal">Thanks in advance!</p>
