On the standing-eddy sensible heat transport reversal in the polar region of the northern hemisphere during winter

摘要: Harmonic analysis of the standing-eddy transport sensible heat in Northern Hemisphere polar latitudes shows that equatorward transfer these January is due to different zonal harmonics at and isobaric levels. A comparison transports by standing eddies, up meridional temperature gradient, midlatitude lower stratosphere troposphere, up-gradient are mechanisms. The former caused a relative maximum time-and-zonal average which owes itself mean circulation, does not involve any changes structure eddies; but latter cross-latitude direction tilt vertical axis eddies.
