Traffic Bottlenecks: Predicting Atmospheric Blocking with a Diminishing Flow Capacity
Published in Geophysical Research Letters, 2024
Using NH18 to define LWA flux exceedance events, this paper explores predictors of blocking onset in the traffic jam theory. A downstream reduction in flow capacity is common for both exceedance and blocking events, similar to how lane closures favor traffic jams. Blocks are co-located with exceedance events in space but not in time, limiting the predictive utility of the traffic jam theory.

Machine Learning on Dynamical Systems
EAPS course notes, MIT EAPS, 2025
I’ve started taking an off-cycle course 12.S592 on machine learning taught by Sai Ravela, with a focus on (non-Gaussian) dynamical systems. My desired final project is on extratropical cyclone downscaling, using a reduced stochastic model. Here are some PSet notes and schematic solutions, because they are very interesting problems to think about.
