“At the forefront of hydrological research, I harness the power of advanced climate simulations to understand and project extreme weather events. My mission is to provide actionable insights for effective flood and drought management, ensuring communities are prepared and protected.”
Youngil Kim

I am a water and climate scientist specialising in regional climate modelling, hydrological extremes, and high-resolution climate analysis. I completed my PhD at the Water Research Centre, University of New South Wales, and have since worked across academic, government, and collaborative research programs in Australia.
My research focuses on understanding how climate variability and long-term warming influence extreme rainfall, drought, floods, heat, and water availability. I use regional climate models, hydrological analysis, observations, and large-scale climate datasets to investigate these changes at the local and regional scales where their impacts are most directly experienced.
A major component of my work involves improving the accuracy and physical consistency of regional climate simulations. My research on the comprehensive bias correction of regional climate model boundary conditions developed new methods to reduce systematic errors in the large-scale atmospheric information used to drive high-resolution models. This work helps produce more reliable simulations of hydrological extremes and future climate risks.
I am particularly interested in how higher-resolution models can better represent coastlines, topography, rainfall processes, and short-duration extremes across Australasia and the Pacific. By evaluating model performance and uncertainty, I aim to improve the scientific basis for climate risk assessment, water resource planning, and resilient infrastructure design.
Through this website, I share research findings, scientific visualisations, practical tools, and accessible explanations of weather, water, climate modelling, and extreme events. My broader goal is to connect advanced climate science with the real-world decisions required to prepare for a changing climate.
