Biography
Pappu is Ph.D. student in the Department of Physics at the University of Illinois. He is the member of CDDS@UIUC since fall 2022. He is trying to better understand the feedback loops that determine the magnitude of global warming. He run climate model simulations to understand the physics linking surface warming, atmospheric circulation, and top-of-atmosphere radiation.
Pappu has some teaching experiences, after his master’s he joined several public and private universities in Bangladesh as a junior faculty. He did his undergraduate and master’s from the Department of Physics, University of Dhaka, Bangladesh. From his master’s time he worked numerus project related to severe weather such as thunderstorms and lightning. He has several published articles about thunderstorms and lightning prediction using numerical model.
Pappu loves to play and watch cricket with his friends. In his spare time, he tries to go out and explore new places. He loves to eat and cook spicy food.

Research Description
Climate models have a wide range of sensitivities in response to increased greenhouse gas concentrations, and differences in feedback processes that amplify or attenuate the original radiative disturbance are one of the main concerns of climate change. This radiative disturbance relies on the sea surface temperature pattern of different areas and so it can change with time as SST patterns evolve which is called the pattern effect. It is conceivable to analyze variations in atmospheric radiative fluxes caused by feedback from the atmosphere and surface temperature, water vapor, and surface albedo by using radiative kernels at the top of the atmosphere.
For this study, we have planned to perturb the temperature in different locations by using the aquaplanet symmetric setup of the Community Atmospheric Model (CAM5), CESM1.2.1. In this simulation, we will consider the physics of atmospheric circulation, top-of-atmosphere radiation, and surface warming, which will give us the concept of a feedback loop. We hope that these simulations will help us understand the feedback loops that determine the magnitude of global warming.
