Abstract

TC Camille (1969) and TC Danny (1997) both interacted with the equatorward entrance region of an upper-tropospheric jet as they traversed the Appalachian Mountains; however, their societal impacts differed. During the 12-h period starting 0000 UTC 20 August 1969, 690 mm of rain fell over Massies Mill, Virginia, as TC Camille traversed the central Appalachian Mountains. On 24 July 1997, TC Danny underwent inland reintensification while moving across the Carolinas. TC Danny's minimum central mean sea level pressure decreased from 1012 hPa to 1000 hPa and its maximum sustained wind speed increased from 20 kt to 40 kt during the 18-h period starting 0000 UTC 24 July. The main objectives of this thesis are to document the synoptic-scale environments and underlying mesoscale processes responsible for each TC–jet interaction, and to document important mechanisms and processes that lead to inland flooding associated with TC–jet interactions and inland reintensifying TCs that interact with midlatitude jets.
