At the shift, the surface of the Earth will move, in just under an hour, more than a quarter turn. Where massive earthquakes and tidal waves occur when this motion stops, Hurricane Force winds, world wide, occur during this shift. Humans are used to predictability in regard to violent winds, even in the case of tornadoes and wind shears that drop planes suddenly. The weather patterns are such that these destructive winds can occur, spoken of as tornado weather or conditions likely to produce wind shear. Hurricanes, or their eastern equivalent, typhoons, give lots of warnings, not only that they are brewing but also, by increasing wind force, that they are on the way.
During the shift, the atmosphere of the Earth does several things, all at once.
Due to the amount of mobility, with all air masses in motion, and to the pulling upward and ripping away of the upper stratas, pressure at any given point is not as extreme as one might think. Yes, the atmosphere is in motion, and yes, the whipping and confused winds might reach hurricane force during this hour and be unpredictable for several hours after the shift, but one should not assume a force of winds above what the world experiences today. Your hurricanes and typhoons represent what occurs when air masses attempt to move against each other, given their density and gravity attraction and inertia. These same factors are in place, are predominant, during the pole shift. Humans wishing to prepare for these violent winds should anticipate a force equal to their familiar hurricanes, not tornado force, although tornadoes will be spawned. Stay below the Earth's surface, lie low, and tie down everything you wish to find when it's over.
