<br>
'tg2' is wind variable (KPH)<br>
<br>
<font face="Dax">'define wis=pow((tg2),0.16)'<br>
'define windchill = 13.112 + 0.6215*(t-273.15) - 11.37*wis +
0.3965*(t-273.15)*wis'<br>
'd windchill'</font><br>
<br>
<span lang="en"><span>I
find</span> <span>little difference, </span></span>
<span lang="en"><span>I
wonder...</span></span><br>
<span lang="en"><span>It</span><span>'ll be</span> <span>well calculated.. Do </span></span>
<span lang="en"><span>you
calculate</span> <span>the</span> <span>windchill</span> <span>otherwise</span>
<span>...</span></span> ?<br>
<br>
Date / wind (KPH) / temp (ºC) / windchill (ºC)<br>
