I have been working as a scientist at the India Meteorological Department, Pune, India, since March 2021. Prior to this, I had worked in Climatic Research Unit, School of Environmental Sciences-University of East Anglia, United Kingdom (2017-2021), the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Japan (2010-2013, 2014-2017), the Euro-Mediterranean Center on Climate Change (CMCC), Italy (2013-2014), and the Centre for Development of Advanced Computing (CDAC), India (2008-2010).
The aim of my work is to advance our knowledge of large-scale ocean-atmosphere interactions and their influence on climate. In particular, I am interested in the problems of the role of the ocean on climate variability ranging from interannual to multidecadal time scales and diagnosing physical mechanisms. Some of the examples of my study include ocean-atmosphere interactions through El Niño–Southern Oscillation (ENSO)/Indian Ocean Dipole (IOD) and their interactions with the Indian summer monsoon, understanding the response of the Asian climate to Atlantic Multidecadal Oscillation (AMO), etc. I do my research using a combination of atmospheric models, model output (CMIP5/CMIP6), observation, reanalysis, and proxy data - to study various weather and climate processes with spatial scales ranging from mesoscale to synoptic scale and timescales ranging from short-range to multidecadal climate.
Recently, in my current capacity at the India Meteorological Department, I started involving more with operational climate predictions and services - this includes seasonal climate forecasts over India, preparing ENSO/IOD forecast bulletins, climate monitoring and analysis over India, drafting climate summary of India, and teaching climate sciences to meteorological personals at the Meteorological Training Institute, Pune (A WMO Regional Training Centre). Also, as a member of the WMO Regional Climate Centre (RCC Pune), I contribute organising South Asian Climate Outlook Forum (SASCOF) and Climate Services User Forum (CSUF) in collaboration international organisations and National Meteorological and Hydrological Services (NMHSs) of South Asia.
The goal of my research is to understand the physical processes that control climate systems and to improve our ability to predict climate variability and change. Also, to provide improved climate services to user sectors for the benefit of society.
I have a M.Sc degree in Oceanography and M.Tech. degree in Atmospheric Sciences. In 2009, I received my Ph.D. in Meteorology from the Department of Meteorology and Oceanography, Andhra University, India, and my doctoral research was focused on the numerical modeling of Indian summer monsoon processes.
