Vir ‘n verandering gaan ek nie ploeg met ‘n digter se kalwers nie, maar met ‘n klomp ingenieurs s’n (http://www.engineeringtoolbox.com/wind-chill-effect-d_112.html – terloops, hulle toolbox het ‘n hele spul baie interessante en nuttige goed in):
Wind Chill Index – Wind Velocity km/h and degrees Celsius
The “Chilled” air temperature can also be expressed as a function of wind velocity and ambient air temperature as
twC = 13.12 + 0.6215 ta – 11.37 v0.16 + 0.3965 ta v0.16 (1)
where
twC = effective “wind” temperature (oC)
ta = air temperature (oC)
v = wind velocity (km/h)

(Maar voor jy jouself TE jammer kry, dink aan die mense in Siberië!)

dankie vir die somme, waar is die laaste kolom vir koel, koud, kouer, yskoud, bleddie koud, f*kken koud
Dis ‘n baie handige tool hierdie as mens vooraf wil weet hoeveel jasse jy moet aantrek.
Geeftag, geen wonder die honde het my vandag omgedraai nie. Die windjie was darem baie skraal.
Gmf, ek het nie gesê hulle moet in Siberië gaan bly nie.
