2604.01261 Ozone Hole Recovery Has Shifted Southern Hemisphere Westerlies Equatorward by 1.2 Degrees: Detection in 40 Years of Radiosonde Data
This study presents a comprehensive quantitative analysis of ozone hole recovery and its relationship to westerly winds, drawing on multiple decades of observational data and high-resolution numerical simulations. We develop a novel statistical framework combining wavelet decomposition, Granger causality testing, and bootstrapped trend analysis to establish robust quantitative findings.
