My current work focuses on two areas: the Korean Climate Model for the national climate prediction system, and physics-based wildland fire modeling. They rest on earlier work in mesoscale dynamics, clouds and nonlinear dynamics. Select a topic for details, figures and related papers.
CLIMATE MODEL
Korean Climate Model for the National Climate Prediction System
Korean Climate Model for the National Climate Prediction System
Contributing to the development of K-CM, Korea's coupled atmosphere–land–ocean–sea-ice climate model (국가기후예측시스템).

WILDLAND FIRE
Wildland Fire Modeling
Wildland Fire Modeling
Physics-based fire modeling with FIRETEC, FARSITE and WRF-SFIRE from meter scale to national scale, fuel maps for accurate modeling, and AI emulators trained on large FIRETEC ensembles.
ATMOSPHERIC DYNAMICS
Orographic–Convective Flows and Gravity Waves
Orographic–Convective Flows and Gravity Waves
Linear theory and simulations of flows forced by mountains and convective heating together, the momentum the waves carry, and downslope windstorms in the lee of mountains.
CLOUD MICROPHYSICS
Aerosol–Cloud–Precipitation Interactions
Aerosol–Cloud–Precipitation Interactions
How aerosols change cloud droplets, ice and precipitation, from idealized orographic clouds to real cases and deep convective systems.
LAND · LAKES · ATMOSPHERE
Atmosphere–Land/Ocean Interactions
Atmosphere–Land/Ocean Interactions
How lakes reshape precipitation around them, from the diurnal cycle over Lake Victoria to summertime rainfall over Lake Baikal, and how convective cold pools interact with the land surface and soil.
URBAN ENVIRONMENT
Urban Meteorology and Air Quality
Urban Meteorology and Air Quality
Urban breeze circulations and their interaction with mountain winds, urban heat islands and heat waves, and observations of air pollutants in urban street canyons.
NONLINEAR DYNAMICS
Chaos and Predictability
Chaos and Predictability
Physically extended and high-dimensional Lorenz systems as minimal models of thermal convection.
FIELD & LAB
Experiments and Field Campaigns
Experiments and Field Campaigns
Prescribed fires on the Kansas prairie, a cold-pool network in Germany, rooftop, street, and urban park measurements in Seoul, and a laboratary experiment.
