Executive Summary : | Climate change is a global issue due to the destructive effects on various sectors, including water resources, public health, energy, and agriculture. Mapping possible changes in the climatic parameters is crucial for planning climate change adaptation and mitigation strategies. India receives major portion of rainfall during monsoon season (June to September). A major advantage of GCMs is their ability to predict future climate in response to various atmospheric GHG concentration scenarios. Most GCMs are associated with a large degree of uncertainty, CMIP6 GCMs differ from previous CMIPs in that the newest version provides a more accurate depiction of the Earth’s physical processes. By analysing the CMIP5 future scenario, it is identified that, the frequency of the extreme rainfall events are increasing in the future scenario (Sharmila et al., 2013). The updated climate projections from the CMIP6 group of models enabling the development of new scenarios to better evaluate the consequences of climate change policies. CMIP6 places a premium on coordinated experiments to gain a better understanding of the processes behind climate variability (Arias et al., 2021). It is essential to analyse the variability of extreme precipitation events in CMIP6 historical and future projections. To bridge this scientific gap, present proposal aims to understand the variability (frequency, intensity, and duration) of extreme precipitation events over the Indian region by implementing the downscaling techniques. The present study also aimed to understand the physical mechanisms that are responsible for changes in extreme rainfall events and link with large-scale climate modes. |
