Scientists routinely observe
atmospheric waves around the world, but the persistence of these
waves made them
unusual, and scientists didn't know what was causing them.
This very
unusual atmospheric configuration — in which the large - scale
atmospheric wave pattern appears to be largely «stuck» in place — has been characterized by a seemingly ever - present West Coast ridge and a similarly stubborn trough over central and eastern United States (commonly referred to in media coverage as the «Polar Vortex,» though this terminology is arguably problematic).
Because the longwave
atmospheric weather patterns (Rossby
waves) have a scale of several thousand kilometers, it is not
unusual for the temperature of a region the size of the United States to be substantially warmer or co lder during a single season than the zonal mean temperature.
