polar vortex---The spinning pattern of cold over earth’s
magnetic poles, which feeds off the difference in temperature between latitudes.
Evidently, the difference in temperature is lessening at this time, flattening
the vortex out over the relatively lower latitudes into more of a wave of cold
air.
