Description:
S0 News on two major atmospheric changes and a shattered record. Today's links are a reversed Arctic polar vortex and a paper on anomalous quasi-biennial oscillation (QBO) changes in 2023–2024.
The polar-vortex page says the Arctic vortex has reversed: winds around it blow from the east at 2 m/s, about 30 m/s weaker than the 1991–2020 normal for 11 November. The linked paper compares 2023–2024 equatorial wind and total ozone with the usual QBO cycle and reports an anomalous change.
