A New Theory for Diabatically-Induced Along-Stream Jet/Front Formation and Its Role in Severe Weather
Abstract
During the course of this contract, a great deal of analysis, synthesis, and writing was undertaken in an effort to construct a general theory of how along-stream frontogenetical/jetogenesis processes create an environment conductive to severe convection. After performing numerous mesoscale simulation experiments for three different case studies, i.e., the 27-29 March 1984, 11-12 July 1981, and 27-28 Match 1994 case studies the patterns are coalescing which are apparent in all three case studies. These patterns indicate how mesoscale mutual mass/momentum adjustment processes organize along-stream jet/front systems and how said systems produce the vertical wind shear and instability necessary for severe convection. These patterns can be employed to construct a paradigm of how a hydrostatic environment conducive to severe weather eventually evolves over the central and eastern U. S. when synoptic scale jet streaks are juxtaposed over the Rocky Mountain west particularly, exclusively, during the spring and summer months.
