Tropical Cyclone Multi‐Level Wind‐Speed Structure Reconstruction From Sparse Dropsonde Data Via Adversarial Learning

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Tropical cyclones (TCs) pose significant global hazards due to their intense winds, heavy rainfall, and associated storm surges. While in situ observations from aircraft are crucial for understanding TC structures, these measurements are often spatially sparse, limiting the characterization of the wind speed structure.
