[gradsusr] Wind-chill parameter GrADS -

[Leopoldo Alvarez]

Hi alls,

I am trying to calculate the Windchill and i have used this expression ->
http://www.wrfems.info/viewtopic.php?f=6&t=742

'tg2' is wind variable (KPH)

'define wis=pow((tg2),0.16)'
'define windchill = 13.112 + 0.6215*(t-273.15) - 11.37*wis + 
0.3965*(t-273.15)*wis'
'd windchill'

I find little difference, I wonder...
It'll be well calculated.. Do you calculate the windchill otherwise ... ?

  Date / wind (KPH) / temp (ºC) / windchill (ºC)
