Frontogenesis and geostrophically forced secondary circulations in the vicinity of jet stream-frontal zone systems.

Abstract

Frontogenesis and geostrophically forced secondary circulations in the vicinity of jet stream-frontal zone systems are treated, assuming that the motions conform to the geostrophic momentum approximation and that the secondary circulations are confined to the cross-front plane. Absolute momentum is used as a frontal defining parameter as its spatial discontinuities are shown to bound the total hypergradient domain of upper jet-front systems. -from Author
