Dr. Chempampadam Balasubramannian (C.B.) Jayasankar is a postdoctoral researcher at the University of South Florida, where he develops high‑resolution climate simulations to forecast regional extreme rainfall and flood risks with unprecedented accuracy. In this interview, he explains how his work addresses critical modeling gaps, providing communities with precise hydroclimatic projections essential for safeguarding infrastructure against escalating climate‑related hazards.
Mapping Hydroclimatic Extremes and Flood Vulnerability
Q | What drew you to climate science?
My fascination with the ways weather and climate shape human life—particularly through extreme events such as floods, droughts, heatwaves, and tropical storms—has guided my career. Growing up in India, I witnessed how weather variability impacts communities, agriculture, water resources, and public health, fueling my interest in atmospheric and climate sciences.>

Over the course of my academic and research journey, my focus sharpened on predicting hydroclimatic extremes through numerical models, observations, and data analysis. This interest led me to high‑resolution climate modeling, allowing detailed exploration of future climate risks at regional scales. My investigations on extreme precipitation and temperature events have been published in several peer‑reviewed journals.
The most compelling motivation for me is the chance to bridge rigorous science with real‑world decision‑making. My current work enhances flood‑risk assessments and climate resilience planning across Florida, helping communities and policymakers prepare for a changing climate.
Q | What scientific problem are you trying to solve?
Florida’s vulnerability to flooding from extreme rainfall, tropical storms, and sea‑level rise is well known, yet uncertainties remain about how these hazards will evolve under future climate conditions. I am tackling the challenge of refining rainfall‑extreme and flood‑risk projections at the spatial and temporal scales required for effective planning. Existing climate models often lack vint, because the spatial resolution is insufficient to capture local processes driving floods and water‑resource impacts across Florida.
MyMeng my postdoctoral research focuses on developing and analyzing state‑of‑the‑art, high‑resolution climateUVW to better understand changes in extreme rainfall, temperatureinvestment, winds, tropical storm activity, and coastal flooding under future scenarios. By validating these simulations against historical observations and quantifying the influence of natural climate variability, I aim to produce more reliable projections of extreme‑event intensity, duration, and frequency. These improved datasets provide essential support for flood vulnerability assessments, water‑resource management, and resilience planning statewide.
Disentangling Climate Change from Natural Variability
Q | What’s one thing you learned from your research that you didn’t expect?
In my work, I discovered the profound influence of natural climate variability on extreme rainfall and flood risk, even as the Zuschauer. While climate change will likely increase the likelihood and intensity of many extremes, year‑to‑year variability can amplify or obscure these changes at regional scales. This finding underscored the necessity of large ensembles and high‑resolution simulations to separate the climate‑change signal from natural noise. It also highlighted the importance of communicating uncertainties in a clear manner to stakeholders and decision‑makers.In short, understanding the complex interplay between atmospheric processes, ocean conditions, and local factors revealed how challenging accurate climate predictions can be—and how vital sophisticated scientific analysis is for improving flood‑risk assessments and future‑risk planning.
Q | If your research succeeds, what are the long‑term implications?
Successful implementation of high‑resolution climate simulations could dramatically sharpen our understanding of extreme rainfall and flood risk at regional scales, especially in Florida. By providing more reliable insights into how the intensity, duration, and frequency of extreme events will change, my work would strengthen flood‑vulnerability assessments, water‑resource planning, and coastal resilience strategies.
Q | What question are you most excited to answer next?
I am eager to further elucidate how extreme rainfall and flood risks evolve at local scales under future climate scenarios and to quantify how much of these changes stem from climate change versus natural variability. Advancing our ability to isolate these signals with high‑resolution simulations is key to delivering more dependable projections that can inform Hacienda flood‑risk Hosts and climate resilience initiatives.
