Front-Boundary Layer Models from STORM-FEST Observations

Abstract

The STORM-FEST field campaign to investigate atmospheric frontal structure and evolution provided data on deformation frontogenesis observed 20- 21 February 1992. These data have been analyzed, and the principal features compared with the theoretical predictions of a semi-geostrophic inviscid, adiabatic model. The overall agreement is good, although viscous and thermal diffusion in the planetary boundary layer is omitted from the theoretical model. The relative importance of terms neglected in the semi-geostrophic model, including ageostrophic accelerations, viscous and nonadiabatic contributions will be evaluated during the second year of the investigation. Modification of the theory to include neglected effects will be attempted to improve low-level predictions of frontogenesis. Completion by May 31, 1995 is anticipated.
