Wind chill index
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.
wci(taverage, w, data_names = NULL, time.scale = YEAR, na.rm = FALSE)
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? |
index value
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
