Synoptic-scale differences in the characterization of high-shear low-CAPE tornado outbreaks in the United States

High-Shear Low-CAPE (Convective Available Potential Energy) (HSLC) Tornado Outbreaks (TOs) are a specific subset of TOs that occur each year, primarily East of the Rocky Mountains. This study looks to define HSLC TOs with the use of quartiles of the most supported shear and CAPE measure, create a climatology of HSLC TOs, and to give a better description of the synoptic-scale patterns associated with HSLC TOs. Statistical analysis of quartiles and inner quartile range (IQR) were conducted to see which is the best measure. Ultimately, Mixed-layer CAPE (MLCAPE) and 0-3km shear were used due to past support and were used to define HSLC TOs. Bootstrapping was conducted, and compositing was created for each of the five regions. Bootstrapping between some regions showed statistical significance, and some of the composites matched up closely to what was seen in past HSLC research.
