Abstract

abstractRadiosonde sounding-derived parameters are analyzed for 54 cases of tornado outbreaks associated with tropical cyclones from 1995–2010. The goal of this study is to provide a climatology of sounding-derived parameters for each tropical cyclone tornado outbreak. Sounding parameters provide information on environmental characteristics such as moisture, stability, and wind shear within the atmospheric column. Descriptive statistics for the 12 sounding-derived parameters are presented to document the central tendency and variability of atmospheric conditions associated with these outbreaks. Additionally, results of both a Cluster Analysis and Principal Components Analysis of the parameters are presented to aid in understanding commonalities in groups of sounding-derived parameters and tornado outbreaks.
