摘要：Due to global warming, increase in air temperature is a growing concern at present. This rise intemperature may cause mild to severe thermal discomfortability and heat related hazards mostly for the people who areengaged in outside activity throughout the day. The present study shows the distribution of thermal loads over fourcoastal stations of India viz, Digha (22.38º N, 87.32º E), Visakhapatnam (17.68º N, 83.21º E), Thiruvananthapuram(8.48º N, 76.95º E) and Goa (15.49º N, 73.82º E). In this present study Wet Bulb Globe Temperature (WBGT) is usedto estimate the thermal stresses by using last ten years’ meteorological data. It is observed that 36%, 43%, 55% and35% days of summer months are fall in the partial discomfort category (II) for Digha, Visakhapatnam,Thiruvananthapuram and Goa respectively. It is interesting to note that 2.53% and 6.82% days of winter season of Goaand Thiruvananthapuram are also in the same zone. Severe stresses are observed in the East coast during summer andmonsoon months. A positive trend varying from 0.30ºC to 0.45º C per year is observed for all the Coastal stationsexcept Thiruvananthapuram. Regional based Discomfort Index (DI) scale is also proposed in this study.
