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. WebDuring the mid-century years (1935–1965), researchers focused on the structural characteristics of fronts and their associated jet streams near the tropopause, and on the diagnosis of the frontogenetic processes and …
