Compared to many other weather phenomena, the life-cycle of hurricanes is poorly understood; therefore it is difficult to predict how a hurricane might behave after it makes landfall. One thing in particular that is hard to predict is whether a hurricane that has made landfall will produce tornadoes or not. Prior studies have described some of the characteristics of hurricanes that seem to produce tornadoes. This study will examine tropical storms and hurricanes that made landfall in the United States between 1975 and 2004, to validate results of previous studies (Novlan and Gray, 1974 and McCaul, 1991) and to understand the climatological conditions that favor tornado genesis. In particular, it will examine the area of landfall, time of landfall, storm-dissipation rate and vertical wind shear of the horizontal wind of three categories of tropical storms and hurricanes, storms that do not produce tornadoes, storms that produce tornadoes and storms that produce tornado outbreaks (8 or more tornadoes).
