Abstract
The study of tornado outbreaks has been well documented, however, there has only been a few on Florida tornado outbreaks. This study details the composite dynamic and thermodynamic conditions associated with these events. Consistent with past research, a tornado outbreak was defined as 4 or more tornadoes occurring within a 24-h period during the winter and early spring months (Dec–May) from 1979–2016. December–May was chosen to eliminate tornado outbreaks that were associated with tropical cyclones.
In total, 35 outbreaks were identified using archived severe weather reports. Composites were produced using the North American Regional Reanalysis (NARR).Initial results show Florida tornado outbreaks are associated with a negatively tilted mid-tropospheric trough (dynamics), moderate CAPE and low LCLs (thermodynamics), strong lower-tropospheric wind shear, and the upper-level divergent exit region of the Polar Front Jet (PFJ).
