Description:

An overview of the synoptic and subsynoptic controls on three tornado episodes (seven tornadoes) in northern and central California during December 1992 is presented and compared to the "prototype" documented for the 24 September 1986 mesocyclone-induced F2 event in the Sacramento Valley. Convective and rotational parameters calculated interactively on the SHARP Workstation verified anecdotal evidence that two of the three December episodes were mesocyclone-induced. The study indicates that careful consideration of subsynoptic analyses and buoyancy and shear parameters can indicate a mesoscale focus for supercellular development in California "cold sector" thunderstorm environments.
