Fascinating question. I don't know much about how ridges/troughs gravitate to certain longitudes, and what it takes to buck the trend.

Recent south polar warmth (negative AAO → SAM; gradually easing) has pushed westerlies further north, and produced a wavier jet stream pattern with persistent mid-latitude cold and warm anomalies. Which longitudes are cold/warm is governed by planetary waves.
850 hPa zonal wind anomaly between 20 September and 5 October 2025 from NCEP/NCAR Reanalysis. 500 hPa geopotential height and anomaly between 20 September and 5 October 2025 from NCEP/NCAR Reanalysis.

Wonderful analysis. This would have been one of the "journeys through the atmosphere" Clyve took ASWA folks on at the time. Spellbinding stuff.

Another stupendous Southern Ocean low (939 hPa) between Australia and Antarctica. Spring is conducive because of the heightened contrast between polar and midlatitude air masses - and higher sun elevation makes for great (visible) satellite imagery!
