A 10,000-Year Global Stochastic Tropical Cyclone Catalog with Wind-Dependent Track Transitions (WHITS)
Jennifer Nakamura, Upmanu Lall
Reliable assessment of tropical cyclone risk is limited by the short and spatially uneven historical record, especially for rare, high-intensity landfalls that dominate insured los…
Steering Tropical Cyclones Using Small Perturbations in an AI Weather Model
Qin Huang, Moyan Liu, Yeongbin Kwon +1
Tropical cyclone (TC) trajectories are governed by large-scale steering flows and exhibit sensitive dependence on atmospheric initial conditions. Using Hurricane Sandy (2012) in th…
Urban Flood Observations: A hand-labeled training and validation dataset of post-flood inundation
Rohit Mukherjee, Hannah K. Friedrich, Beth Tellman +5
Urban flooding affects lives and infrastructure worldwide. Mapping inundation in complex urban environments from satellite imagery remains challenging due to limited spatial resolu…
Real-time Coordination of Cascaded Hydropower under Decision-Dependent Uncertainty
Eliza Cohn, Ning Qi, Upmanu Lall +1
This study proposes a real-time control framework for cascaded hydropower systems that incorporates decision-dependent uncertainty (DDU) to capture the coupling of streamflow uncer…
Instability-Aware Steering of an Extreme Atmospheric River in an AI Weather Foundation Model
Moyan Liu, Qin Huang, Upmanu Lall
Advances in deep learning methods for weather forecasting are creating opportunities to computationally explore the potential for steering or control of extreme weather trajectorie…
An Attention-Based Stochastic Simulator for Multisite Extremes to Evaluate Nonstationary, Cascading Flood Risk
Adam Nayak, Pierre Gentine, Upmanu Lall
Flood risk is correlated in space and time, challenging insurance systems that rely on diversification across assets. Financial instruments governing flood coverage are typically s…
