This is called the polar vortex.Those strong winds are about to slow down completely, and might even revert direction. We call it a “vortex breakdown” or “Stratospheric Sudden Warning”, and in the Southern Hemisphere it only happens for the second time that we know of, and certainly since the era of satellite measurements began in the late 1970s.
