Exposure
Exposure of a system is its extent of being exposed to variations in climate conditions in that particular area unit. Various Indicators of exposure included in computation of vulnerability index are: change in annual rainfall, change in June rainfall, change in number of rainy days, change in maximum temperature, change in minimum temperature, change in incidence of extremely hot days, change in incidence of extremely cold days, change in frequency of occurrence of frost days, change in drought proneness, change in incidence of dry spells of >= 14 days, extreme rainfall events, change in 99 percentile rainfall, change in number of events with > 100 mm rainfall in 3 days, change in maximum rainfall in a single day as % to annual normal and change in mean maximum rainfall in 3 consecutive days as % to annual normal (CRIDA, 2013). On the basis of sensitivity index districts of Odisha are categorized into five broad categories such as very low exposure, low exposure, medium exposure, high exposure and very high exposure.

Jagatsinghpur, Puri, Cuttack, Gajapathi, Malkanagiri
