Purpose: Estimating wind chill index as one of the indexes effective in body comfort, specifically for athletes and tourists interested in winter sports.

Methods: Meteorology data including temperature and the percentage of relative humidity of 6 synoptic stations of Chaharmahal-Bakhtiyrai province, Iran from 1990 to 2007 were extracted from Iranian Meteorology Site. In order to calculate the values of wind chill, the innovative formula of NOAA Meteorology Services Center [T (WC)= 35.74+0.6215T-35.75V+0.4275TV] was used.

Results: After analyzing wind in all stations, it became evident that the great percentage of wind calm related to fall, and spring had the most wind distortions. In studying the mean temperature during this studying period, Koohrang station with mean of 9.8C was identified as the coldest station and Lordegan with a mean of 17C represented the warmest station of the region observed. According to degrees derived from wind chill index, Koohrang station in January with a mean of ?28.75 was known as the coldest and roughest station.

Conclusion: Among the studied stations, Koohrang had the most intensive degrees of wind chill occurrence and Lordegan had the calmest conditions. Therefore, athletes and tourists should use warmer clothes and covers in cold seasons in Koohrang in comparison with other studied regions, in order to protect themselves from the negative effects of sudden cold and occurrence of intense wind chills.
