Abstract : A high density of surface and upper air observations, including aircraft observations, were accumulated during the STORM-FEST Experiment in the central United States (1 February-13 March 1992). These data are being analyzed to identify significant internal gravity wave and turbulent activity that occur in association with low-level frontal passages. The principal analysis method is local decomposition using wavelets as basis functions. These functions provide information on both scale and translation of coherent events, and are well- suited for frontal analyses,. Dissipation of kinetic energy in frontal zones will be determined using data obtained during STORM-FEST. This information will be used in conjunction with theoretical modeling of the frontal scale contraction process that is currently poorly understood....
