This Lessons from History article about the wind-chill index (WCI) explores historical polar and meteorologic literature relevant to topic presents unpublished work 1939. Geographer Paul Siple (1908–1968) was a 6-time Antarctic explorer scientist who invented named WCI in his doctoral dissertation at Clark University. Charles Passel (1915–2002) performed studies Antarctica 1940 that led publica...

A thermal manikin with constant skin temperature and a wind-chill tunnel with constant air temperatures and wind speeds were used to measure whole-body heat loss for seven ensembles chosen to represent the full range of civilian outdoor clothing in use for everyday, nonsporting wear. Equations fitting the data with correlation coefficients exceeding 0.99 were derived for each ensemble, and diag...

Effective temperature is a term used to rate the cooling or heating power of the physical environment in terms of dry bulb temperature. For livestock exposed to cold, windy environments, effective temperature must now be predicted by a wind-chill index prepared for humans and designed without regard to extemal insulation_ suck~hai r or wool. The human wind-chill relationship is quadratic in nat...

OBJECTIVE To determine whether climate variability influences the number of hospitalizations for respiratory diseases in infants, children, and adults in the city of Campo Grande, Brazil. METHODS We used daily data on admissions for respiratory diseases, precipitation, air temperature, humidity, and wind speed for the 2004-2008 period. We calculated the thermal comfort index, effective temper...
