STRONG STRATOSPHERIC WARMING IN PROGRESS.  THE VORTEX CENTER SHIFTED
TOWARDS CANADA; THE VORTEX BEING ELONGATED TOWARDS THE BARENTS SEA
AND KASACHSTAN.  AN ANTICYCLONE OVER THE PACIFIC; A NEW ANTICYCLONE
DEVELOPING OVER THE NORTH ATLANTIC.  COLD AIR BEING DISPLACED TO
NORTHERN CANADA; WARM AIR CENTERED OVER CENTRAL ASIA.
