| Summary: | and the LLJ. A statistical analysis of the Eta Model results cyclone was related to the interactions of the upper- and descent of potential vorticity from the stratosphere along an development of a lower-level cyclone. A LLJ developed over During this episode, a trough developed in the lee of the established by 1200 UTC 16 October 1994, as stratospheric followed the descent of high potential vorticity air into the high spatial and temporal resolution of the Eta Model made it indicated that the model provided an accurate representation interacted with the low-level baroclinic zone initiating the isolated in the base of the trough. The upper-level cyclone large-scale forcing. A schematic diagram was constructed LLJ and the ULJ. The rapid development of the surface lower-level cyclonic systems and the LLJ and ULJ. middle troposphere with the cyclone cutting off from the movement of the upper-level low into the northern Great October 1994. Formation of an upper-level low followed of a cutoff cyclone, a low-level jet (LLJ), cyclogenesis, and of the atmospheric situation. The formation of a cutoff low Output from the Eta Model was used to examine the development Plains. To study this event, the Eta Model was chosen. The potential vorticity values descended to levels below 400 hPa. Rockies, and rapid cyclogenesis occurred following the streak propagating to the northeastward from the southwestern suitable for studying the development of the cutoff cyclone surface cyclone, interaction with an upper-level cyclone, the the central United States in association with a deepening the indirect circulation in the exit region of the ULJ; Q- the interaction of these phenomena during the period 16-18 trough in the lee of the Rockies and an upper-level jet (ULJ) United States. The LLJ was coupled to the return branch of upper-tropospheric front. The cutoff cyclone became using existing theories concerning the development of a vector convergence indicated that the LLJ was driven by westerly current when the potential vorticity maximum became |
