The “Predictability Barrier” Phenomenon of Winter Extreme Cold Events in Central and Eastern China and Mechanisms of Error Amplification

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Previous studies have primarily focused on evaluating the forecast skill of extreme cold events in central and eastern China as a whole, with limited attention to their different stages. This study identifies a distinct “predictability barrier” phenomenon in the ensemble forecasts, characterized by rapid growth of ensemble mean forecast error ...
