Arctic Cloud States and Microphysics
How cloud variability, phase changes, and particle histories shape Arctic winter
Why does Arctic winter switch between radiative states?
I use long-term observations and stochastic dynamics to investigate how cloud variability maintains contrasting clear and cloudy states, and why atmospheric models often blur them into an unrealistic intermediate state.
How does cloud physics interact with a changing Arctic climate?
I investigate the two-way link between Arctic cloud microphysics and climate: how cloud processes shape Arctic climate regimes, and how climate change alters those processes in turn.
How do particle histories shape mixed-phase clouds?
I compare observations with particle-based and bulk models to understand how ice growth, transport, and cloud dynamics organize persistent mixed-phase clouds.
