Wind chill over India

Wind chill is a measure of cooling power of atmosphere. In this study, for 15 selected plain and hilly stations In India, wind chill has been computed from Siple and Passel's model for the winter month, ie. December. January and February. Daily temperature and wind data from 5 to 10 years have been used. Utilising hourly values, diurnal variation of wind chill has been discussed for one station. From the covariance analysis attempt has also been made to get true value of wind chill. Relative contribution of wind and temperature towards the chill has also been determined and discussed.

The analysis revealed that the chill is generally of severe intensity. Most of the chill is caused by the temperature rather than wind. It is also found that the model, in Indian conditions, does not truly reflect the cbill.
