Delayed Tropospheric Response over the East Asia–Northwest Pacific Sector to Arctic Stratospheric Polar Vortex Intensity Anomalies
Based on ERA5 reanalysis data (1979–2022) and sensitivity experiments with the WACCM climate model, this study examines the delayed tropospheric response over the East Asia–Northwest Pacific (EANP) region to stratospheric polar vortex intensity (PVI) anomalies. It is found that positive PVI anomalies in the lower str...
