Greetings users.<br>
<br>
I'm writing a script to extract data of a single point in ascii file<br>
(my data set is hourly and I'm extracting daily vaues of max temp, min<br>
temp, max wind, max rel hum, etc... solved).<br>
<br>
But my problem is that I need to obtain the direction of the wind at<br>
the hour of the max wind intensity and the prevailing wind of the day<br>
¿How can I do this?<br>
<br>
Thanks in advance !<br>
