Abstract:

A high density of surface and upper air observations, including aircraft observations, were accumulated during the STORM-FEST field campaign in the central United States 1 February-13 March 1992. These data were analyzed to identify significant internal gravity wave and turbulent activity that occurred in association with low-level frontal passages through the boundary layer. The principal analysis method was local decomposition using wavelets as basis functions. These functions provided information on both scale and translation of coherent events, and were well-suited for frontal and boundary layer analyses. Dissipation of kinetic energy in frontal zones was determined using data obtained during STORM-FEST. This information was used to interpret some of the physical processes in low-level frontal zones, but specific models of the observed events were not constructed.
