About Me

I study cloud microphysics, focusing on how turbulent entrainment and mixing shape cloud droplet size distributions and influence precipitation. My work bridges high-resolution Lagrangian cloud modeling with observational data to improve our understanding of cloud-climate interactions.

Currently, I am working with Dr. Graham Feingold at NOAA Chemical Sciences Laboratory, where I investigate Arctic mixed-phase cloud stability by validating the Lagrangian Cloud Model framework against observational data from field campaigns like MOSAiC.

Research Interests

Entrainment and mixing in warm cumulus and stratocumulus clouds
Warm rain initiation and the role of giant aerosols
Arctic mixed-phase cloud dynamics and stability
Lagrangian cloud modeling at scales from millimeters to kilometers

The Critical Number and Size of Precipitation Embryos to Accelerate Warm Rain Initiation

Jung-Sub Lim, Yign Noh, Hyunho Lee, and 1 more author

Atmospheric Chemistry and Physics, 2025

Abs DOI Bib HTML

Precipitation embryos, such as giant cloud condensation nuclei (GCCN), can accelerate warm rain initiation by bridging the size gap in the cloud droplet size distribution. This study investigates the critical number and size of precipitation embryos required to trigger early rain onset using a Lagrangian cloud model.
