I am a researcher aimed to understand climate change projections at regional scale. It is important to know the possible future changes in mean and extremes of Indian summer monsoon (ISM) due to global warming which has an immense impact on the agricultural production, livelihood of farmers and the economy of India. I try to quantify the projected future changes in mean and extremes of the ISM at the local scale using high-resolution regional climate model. Expert knowledge in WRF-ARW model for weather/climate applications and CAMx chemical transport model for dispersion modelling. Gained extensive experience in porting and running numerical models in the high performance computing (HPC) environment and handling large volumes of datasets.

Academy of Scientific & Innovative Research (AcSIR), & CSIR Fourth Paradigm Institute (CSIR-4PI), India. 2019 Advisor:  Dr. K. Rajendran In this study, we dynamically downscaled an appropriate General Circulation Model (GCM) outputs using a skilful, reliable very high-resolution Regional Climate Model (RCM) of Weather Research and Forecasting-Advanced Research Weather Research and Forecasting (WRF-ARW) to simulate Indian summer monsoon (ISM) and to obtain reliable climate change projection over India and it's orographic west coast. The analysis of the projected changes in mean and extreme events over India and ecologically sensitive, densely populated west coast were carried out after a detailed evaluation of the present-day simulation of ISM by this high-resolution RCM. This high-resolution model with 3-km resolution over WG region resolves orographic features enabling realistic simulation of physical and dynamical characteristics of present-day Indian summer monsoon (ISM) and extreme events over WG, in particular the recent trends in ISM rainfall as observed. Present study establishes the importance of (i) employing skilful high-resolution model, (ii) use of bias-corrected boundary data sets and (iii) configuring model for realistic present-day climate over complex topographic coastlines such as the west coast of India, in order to achieve useful climate change projection information. These climate projections can be effectively used for decision making and adaptation measures in various sectors such as agriculture, hydrology and power generation. |
