The first wind chill formulas and tables were developed by Paul Allman Siple and Charles F. Passel working in the Antarctic before the Second World War, and were made available by the National Weather Service by the 1970s.
Prve formule i tablice za indeks hlađenja razvili su Paul Allman Siple i Charles Passel još prije Drugog svjetskog rata, dok su radili na Antarktici, ali su u upotrebu ušle tek 1970-ih.
