A Spatio-temporal Analysis of Rainfall Trends and Variability Due to Changing Climate in the Central Zone of Himachal Pradesh, India
The drastic change in precipitation as a result of climate change is altering the pattern of stream flows and demands, as well as the spatial and temporal distribution of runoff, soil moisture, and groundwater reserves leading to hazardous events like landslides, floods, drought, etc. Trend analysis has proved to be a potential tool by providing useful information on the possibility of changes of rainfall trends in future. The current study uses the Statistical Downscaling Model-Decision Centric (SDSM-DC) and GIS to evaluate the imminent regional and temporal variations in rainfall caused by various climatic conditions. The study area considered for this study is central zone of Himachal Pradesh. To evaluate rainfall patterns and their reactions to climate variability, seven rainfall stations in the study area were selected. The study concludes that the changing climate has resulted in a significant change in precipitation patterns when compared to previous climatic conditions. Numerous natural hazards, including floods, landslides, cloudbursts, etc., are occurring in the area as a result of the rate of change in seasonal and yearly precipitation over the years as indicated by precipitation trends. Changes in the pattern and an increase in pre-monsoon precipitation are additional significant impacts of climate change.
