Connections between climate oscillations and tornado outbreaks in U.S. landfalling hurricanes
In an attempt to mitigate hurricane-induced tornado risk, a statistical comparison is proposed of tornado outbreaks in landfalling hurricanes along the eastern Atlantic seaboard and Gulf Coast, the ENSO phase, and the Madden-Julian Oscillation in an effort to better predict outbreaks of these tornadoes. The hurricanes that occurred between 1960 and 2007 were sorted into tornado outbreak categories that distinguish between non-outbreaks and outbreaks and then multivariate statistical tests were used to compare that data to SSTs in the Pacific Ocean during the same time period. A relationship was found to exist between the above-mentioned climatic oscillations and outbreaks of tornadoes in landfalling/coastal-interacting hurricanes. It is anticipated that this connection can be used in a predictive capacity to provide improved forecasts of hurricane-related tornadoes prior to landfall, to educate the public, and to reduce the number of hurricane fatalities and destruction of property.
