The GFS and it’s ensembles are forecasting a dramatic reduction in westerly Zonal winds over the North Pole during the latter half of November and throughout December.
Conversely, October and the first half of November brought very strong Zonal winds at 60N, which went hand-in-hand with below-average temperatures at the Pole — Zonal winds in the stratosphere strengthen as the temperature over the North Pole drops:
Looking at the 10hPa temperature chart first, we can see it’s been anomalously cold over the North Pole so far this season, with things really taking a turn for the frigid during the first half of November.
And then sliding to the Pole’s 10hPa Zonal wind strength chart, we see that this dramatic cooling coincided with a sharp strengthening of the westerly winds (after allowing for the standard 2-week delay).
But just look what’s in store for the rest of November and throughout December:
Those westerly Zonal winds are forecast to reduce dramatically over the next few weeks, which would likely indicate high pressure building in the northern latitudes.
The four colored lines in the above chart (turquoise and pinks) are the four individual CFS runs taking us through until March 2020. And all four runs are showing a collapse in the Zonal strength starting now and lasting through December — they could well-be picking up on a Sudden Stratospheric Warming (SSW) event, likely the result of the deep solar minimum our sun is currently suffering.
