Wind chill differences in Python and R

[number9527-12]

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
