Abstract:
In the recent years the important scientific challenge faced by researchers worldwide is to have a better understanding about climate change at a regional scale. However, for all the regions the changes are unequal and have localized intensity. Therefore it should be quantified at a local scale. Climate Variability is defined as variations in the mean state and other statistics of the climate on all temporal and spatial scales, beyond individual weather events. Climate variability and extremes is major contributor to the recent rise in global hunger. Climate change hits the most food-insecure people the hardest. The reason for this growth centered principally on climate shock. Precipitation is one of the important climatic variables responsible for climate change and required to be studied thoroughly. Any change in rainfall pattern due to climate change can adversely affect the agricultural production. Therefore in the current study, an attempt has been made to observe the temporal rainfall variability and trend over a period of 30years (1989-2019) at regional scale for the North Central Plateau in state of Odisha. From the analysis we came into the conclusion that Ten year moving coefficient variation (CV) of seasonal rainfall of Keounjhar showed a increasing trend during kharif season and a constant trend during rabi season and Mayurbhanjh showed a increasing trend during kharif season and a increasing trend during rabi season.
