Wind chill differences in Python and R #124

Open number9527-12 opened 1 month ago

number9527-12 commented 1 month ago

Describe the bug Here are the differences we have identified：

[ ] Calculation of Wind Chill Index (WCI) in Python
[ ] Calculation of Wind Chill Temperature (TWC) in R

`Wind Chill Index (WCI)` in Python

In Python, the function is link:

wci = (10.45 + 10 * v**0.5 - v) * (33 - tdb)

The result is calculated in W/m² and considers the heat loss from a cylindrical flask.

`Wind Chill Temperature (TWC)` in R

In R, the function is link:

twc = 13.12 + 0.6215 * ta - 11.37 * (v^0.16) + 0.3965 * ta * (v^0.16)

The result is given in °C, representing the localized cooling effect on skin due to wind.

@FedericoTartarini and Marcel to review Should we make modifications to the corresponding function file calcTWC.R in the R package?

I believe that these two parameters sound similar, but are actually different concepts. py seems to refer to AHSRAE, while R to ISO
