The contribution of TT Fujita to the understanding of tornado suction marks,spots,swaths,and vortices

Abstract

For years USA Plains state residents wondered why tornado events resulted in the destruction of one neighborhood house while leaving neighboring houses almost untouched. Research conducted during the 1960s and 1970s identified that areas of intense convergence are responsible for this sporadic destruction. Furthermore, research identified six specific types of convergence vortices that may possibly accompany a tornado.
