This year, however, the red mass of warm air traveling up from Siberia burst through the blue concentric circles of the polar vortex on 7 January, pushing cold air down to lower latitudes as seen in the animation above.
However, the influence of blocking on temperatures extends far outside this core region as a subtropical regime has moved northward pushing cold air masses far into the Arctic.
Against a backdrop of rising global temperatures, the changes in atmospheric circulation can sometimes allow warmer air to penetrate unusually far to the north, while elsewhere pushing colder air unusually far to the south.
In winter, this change in flow sends warm air north from the subtropical oceans into Alaska and Greenland, but it also pushes cold air south from the Arctic on the east side of the Rockies.
Well, what seems to happen is this Sudden Stratospheric Warming pushes cold air away from the pole, and we get a freight train of frigid air coming right at us.
This will happen increasingly often under climate change, as melting Arctic ice creates conditions that slow Arctic winds (the jetstream) and make their geographic patterns ever more wavy - with some of those big "waves" pushing Arctic cold deep into the US.
But Iweala can also invoke the bland, vacant tranquillity of his upscale setting in a few potent lines, as when Niru slips out of a church service and sits "down on the steps that push their cold through my corduroy slacks and I pull my blazer tighter around my chest.
