Cloud physics from particles to climate

I study how particle-scale cloud processes shape precipitation, radiation, and climate using stochastic dynamics and particle-based cloud modeling.

About my research

Linking cloud microphysics to climate

I am Jung-Sub Lim, an atmospheric physicist at CIRES and NOAA’s Chemical Sciences Laboratory. I combine stochastic dynamics, particle-based microphysics, and large-eddy simulation to identify the mechanisms that connect the histories of droplets and ice crystals to cloud evolution, precipitation, and radiation.

My work focuses on how particle-scale cloud physics scales up to influence precipitation, radiation, and climate. I also develop the models and computational tools needed to test those connections directly.

Check out my open-source cloud laboratory

DropLab turns particle-based cloud physics into simulations that students and researchers can run, inspect, and modify on a laptop.

Explore aerosol activation, warm rain, mixed-phase glaciation, deep convection, and idealized climate-intervention experiments from the histories of individual super-droplets.
