wci

Wind chill index


Description

Wind chill index is the lowering of body temperature due to the passing-flow of lower-temperature air. It combines air temperature and wind speed.

Usage

wci(taverage, w, data_names = NULL, time.scale = YEAR, na.rm = FALSE)

Arguments

taverage

daily mean temperature, Celsius

w

average wind, m/s

data_names

names of each period of time

time.scale

month, season or year

na.rm

logical. Should missing values (including NaN) be removed?

Value

index value

Formula

WCI = 13.12 + 0.6215 * TG - 11.37 * v ^ {+ 0.16} + 0.3965 * TG * v ^ {+ 0.16}

Where TG in celsius and v is wind speed in Km/h
