a Geopotential height (contour, m2/s2), temperature (shading, °C), and wind (vectors, m/s) anomalies at 100 hPa in February–March regressed onto the zonal wind index (100 hPa, February; see manuscript) during 1980–2001. b Similar to (a), but for March–April. c, d are similar to (a, b), but for 2002–2023.
