Diagnosis of 3D Vertical Circulation in the Upwelling and Frontal …

Webcooling is frequent on the warm side of the frontal zone and warming on the cold side, indicative of descent of the cold air and ascent of the warm air. Fairly definite evidence of such vertical motion exists for 13 of the 20 fronts examined, in four cases the evidence is inconclusive and in three vertical motion appears to have been slight. WebThe object of this thesis is to throw light on the vertical circulation in frontal zones. The partial differential equation for the stream function of the non-geostrophic motion in a frontal cross-section, first derived by Eliassen, A (1962), provides the tool for this study.
