  • Description:
    "A climatology of significant tornadoes (ST) has been developed for the Greenville- Spartanburg, SC (GSP) County Warning Area (C WA). In addition to a time of day/time of year/location climatological analysis, a synoptic climatology has also been developed. This was done to assist operational forecasters in recognizing the 'average' synoptic conditions that typically accompany ST occurrence in the GSP CWA. A sounding climatology and sounding parameter climatology was also developed to assist forecasters in assessing the 'average' environmental conditions that exist during ST events. The results of this study indicate that ST typically occur in the late afternoon and early evening, and are most common from March through May. ST are most prevalent in the Piedmont region of Upstate South Carolina, northeast Georgia, and southwest North Carolina. Meanwhile, ST are extremely rare in the mountainous areas. The typical ST environment is one in which the GSP CWA is located well within the warm sector of a major mid-latitude cyclone. High pressure is located off the east coast, which may be an important detail, since development of cold air damming is unlikely in such a scenario. Finally, ST environments in the GSP CWA are usually characterized by similar values of wind shear, but much weaker instability in comparison with their Great Plains counterpart"--Abstract.
