In this study we consider tornadoes only within a region centered on Russell, Kansas, as defined in Elsner
et al. (2013). The region stretches across the central
Great Plains from northern Texas to central Nebraska
and is bounded by 36.108 and 41.578N latitudes and
102.378 and 95.348W longitudes. This is an area with
a high concentration of tornadoes and where there are
no large spatial gradients in occurrence rates. It corresponds to an area favored by storm chasers. http://bit.ly/1fswIkp
