Abstract

The squall line is generally accepted to be the most commonly observed mesoscale convective system (MCS). Squall lines in the Southeastern United States account for a considerable amount of the total severe weather observed in this region (48%), including the production of localized severe wind events (known as Bow Echoes and Downbursts), long-lived severe wind events (known as Derechoes), as well as tornadoes. This study is the beginning of a baseline severe squall line climatology for the county warning areas (CWAs) of the National Weather Service Forecast Offices (NWSFO) located in Jackson, MS and Memphis, TN. This climatology will focus on the seasonal distribution of severe weather events associated with squall lines, as well as the thermodynamic forcing associated with the initiation and life spans of severe squall lines in Mississippi and West Tennessee.
