As a faculty at the University of Hyderabad (UoH) since 2014, Prof. Ashok has initiated past-climate simulation research in India. His research showcases that the ENSO-Monsoon relationship has always been robust throughout the Last Millennium, but was modulated by the centennial Walker-circulation changes. Simulations carried out by his group indicate a wet monsoon during mid-Holocene due to orbital changes. His results provide usable climate analogue relationships/mechanisms that can be used to delineate the anthropogenic impacts on monsoons future climate simulations. Ashok also works on tropical decadal prediction, climate-prediction applications to crop-yield forecasting, extreme urban weather, etc. Ashok had also contributed to international climate change policy/science deliberations of UNFCCC and IPCC.
