Meteorological Background and Tornado Events of 2011 The most violent tornadoes, with wind speeds of more than 200 mph near ground level, are capable of tremendous destruction. JOPLIN, Mo.

Spatial Analyses of the 2011 Joplin Tornado Mortality: Deaths by Interpolated Damage Zones and Location of Victims BIMAL KANTI PAUL Department of Geography, Kansas State University, Manhattan, Kansas MITCHEL STIMERS Department of Natural and Physical Sciences, Cloud County Community College, Junction City, Kansas (Manuscript received 26 February 2013, in ﬁnal form 8 January 2014) … From 1950 through 2006, tornadoes caused 5,506 deaths and 93,287 injuries, as well as devastating personal and property losses.1 According to tornado occurrence data obtained from the NOAA SPC more than 1,275 … The power of the EF5 Joplin tornado is sometimes muted against the fury of the 2011 season. The STP and its individual … This matched values shown on SPC mesoanalysis maps at 2200 UTC (not shown). — A new engineering study of the damage caused by the May 2011 tornado that struck Joplin found no evidence that it was an EF5, … The analysis further suggests that the locations of Joplin’s record number of deaths caused by the 2011 tornado were in striking contrast to national trends between 1985 and 2012, as well as to the locational pattern that emerged in 2011 for the United States as a whole, particularly for mobile homes and business facilities. While not as photogenic as the Tuscaloosa tornado three weeks before, the Joplin storm left some of the most extreme tornado damage ever documented.
The 2011 Joplin tornado was a powerful and catastrophic EF5-rated multiple-vortex tornado that struck Joplin, Missouri, late in the afternoon of Sunday, May 22, 2011.It was part of a larger late-May tornado outbreak and reached a maximum width of nearly 1 mile (1.6 km) during its path through the southern part of the city. The RUC analysis sounding for Joplin at 2200 UTC (5:00 pm CDT, see 2nd image above), an estimate of the environment roughly 40-45 minutes before the tornado struck, showed very large instability (MLCAPE > 4000 J/kg) and quite sizable low-level wind shear, with 0-1 km storm-relative helicity (SRH) near 300 m2/s2. Engineers concluded that the winds had to be in excess of 205 mph to tear out the parking stops by St. Johns Hospital (Joplin Globe, 2011). Davies, J.

GARNER NOAA/NWS/Storm Prediction Center, Norman, OK (Submitted 21 November 2012; in final form 06 August 2013) ABSTRACT The significant tornado parameter (STP) has been used by severe-thunderstorm forecasters since 2003 to identify environments favoring development of strong to violent tornadoes.
