Tornadogensis within Hurricanes Based on the Orientation of the Rainband to the Coast after Landfall

Abstract:

The focus of this study is to investigate the development of tornadoes within the rainband of a hurricane for various orientations of the rainband when a hurricane makes landfall. The rainband of a hurricane is a common area where tornadogenesis is found depending on the size, intensity, and orientation of the rain band when the storm makes landfall. As a hurricane approaches a coast line, land-surface roughness contributes to surface friction, which can contribute in tornadogenesis. The orientation of the rainband may play a part in the type of supercells that are formed in that rainband and the number and intensity of the tornadoes produced. This study will investigate if the orientation of the rainband leads to the direction in which the supercells rotate, whether clockwise or counter-clockwise, and the scale and intensity of the tornadoes produced.
