The zonal warm phase occurred from the 1910s to 1940s and 1970s to 1990s and is characteristic of strong westerly winds in the northern and southern hemisphere. (watertechbyrie.com)
The researchers established that deep water eddies are likely energised by strong westerly winds over the Southern Ocean that force the ACC and that abyssal mixing, on time scales of months to decades, reacts to this changing atmospheric climate. (sciencedaily.com)
During the first period the stratospheric polar vortex, a system of strong westerly winds at altitudes 10 - 50 km, is projected to weaken, and this weakening slows down westerly winds all the way down to the surface, cancelling out the effect of the increasing temperature difference between the Tropics and the Pole», explains researcher Alexey Karpechko from FMI.
