The dance of air and sea is what weather is all about.
My journey in the realm of atmospheric sciences started with my M.Sc. degree, where I got my first professional training in atmospheric and oceanic sciences. As part of my degree, I performed research on understanding the synoptic-mesoscale feedbacks on heavy rainfall events over the Indian Subcontinent by using a number of satellite and in situ observations. I then tuned the cumulus parameterization scheme in the Weather Research and Forecasting (WRF) model to improve the hindcast of extreme events.
With this background, I joined the Cloud Systems Research Group at the Department of Atmospheric Sciences at the University of Illinois Urbana-Champaign (UIUC) with Prof. Stephen Nesbitt. During my Ph.D., I was primarily trained on applying satellite observations to explore the science of deep convection and its associated cold pools over global tropical oceans. In addition to satellites, I have used buoy and radar data to look at the spatio-temporal structure of cold pools. Moreover, I used regional and global high-resolution non-hydrostatic models to identify environmental controls on cold pools. I also applied a range of artificial intelligence techniques to understand the relationship between mesoscale cold pools and convection. My Ph.D. work led me to create the algorithm to identify tropical oceanic cold pools using satellite scatterometer winds and thus resulting in a global tropical oceanic cold pool climatology for the first time.
After completing my Ph.D., I joined Prof. Kathleen Schiro at the Department of Environmental Sciences, the University of Virginia as a Postdoctoral Research Associate where I extended my Ph.D. work on looking at cold pools and mesoscale convective systems (MCSs) together by combining global MCS datasets with my cold pool dataset. I joined the EVS Division of Argonne National Laboratory with this background as a Postdoctoral Scientist. I will work on creating AI-hybrid models to improve the representation of cloud and convective processes in earth system models.
