Postdoctoral Research

At TU Delft, Netherlands I worked on quantifying and parameterizing the cumulus friction effects in the subtropical shallow clouds. As a part of CloudBrake project, we were interested in if the shallow clouds accelerate or decelerate the trade winds. I used multi-scale modeling from large-eddy simulations to global climate modeling to assess the impacts of cumulus friction.

Previously, I worked with Prof. Steven Sherwood as a Post-doctoral Research Associate at the Climate Change Research Centre, UNSW in Sydney. There, I have explored the role of convection-clouds-circulation coupling in the simulation of climate enigmas, such as mid-Holocene greening of the Sahara desert, the changes in the width of the ITCZ, mysterious mid-level clouds over Sahara desert and Anomalous hydrological changes.

I worked on the dynamics of tropical rain-bands, i.e. the ITCZ and monsoons, during my PhD at the Indian Institute of Science, Bangalore. I investigated the role of various thermodynamic and dynamic processes in deciding the mean location, the vertical structure and the energy exports associated with the Inter-tropical convergence zone (ITCZ) using an idealized modeling hierarchy.

Put together, my research interests are closely aligned with the WCRP's grand challenge on Clouds, Circulation and Climate Sensitivity.

I am also interested in developing simple models and new modeling hierarchies to understand the processes that conspire to form the earth's past and present climate.
