A: Zonal mean weighted average for latitudes between 60–90◦N of water vapour volume mixing ratio (VMR; shading and contour of 1 ppmv; monthly) anomalies for the extended winter 2024/2025 from MLS. Anomalies are expressed as differences with respect to the climatology for the period 2006–2020. Due to missing data, water vapour is visualized as monthly anomalies with interpolated gaps. Due to a retrieval artifact in the 10–8 hPa layer we smoothed the data vertically. B: The average (east-west) zonal wind for 60◦N at 10 hPa for the extended winter 2024/2025 (OW3) in MERRA2. This is near the peak of the polar jet maximum.
