Study of bio-climatic indices over Bihar region

In a changing scenario of weather and climate pattern there is a need to provide more insight in summer and winter seasons by supplying the information of heat stress wind chill index to the public. In this paper efforts have been made to compute the heat index and wind chill index for Bihar region during summer and winter times using national weather service formulae. The results obtained from operational India Meteorological Department (IMD) wind chill effective temperature (WCTn) are more realistic than National Weather Service (NWS) based wind chill temperature index (WCTI) during winter time. The preliminary results obtained from the four stations of Bihar show that it needs more extensive analysis of public responses before standardize in public domain.
