Abstract

The southeastern United States is routinely hit by tropical cyclones. As tropical cyclones track inland and dissipate, their inland impacts can be substantial. Typically, these impacts occur due to any combination of the tropical cyclones heavy precipitation, high winds, or tornadoes. This study will examine the meteorological impacts of 31 inland-moving tropical cyclones from 1985 to 2008. The spatial distribution of meteorological impacts is plotted relative to the track (e.g. left vs. right quadrant) and location (forward vs. rear quadrant) of the cyclone center. Various tropical cyclone attributes, including size, strength, and speed of movement are related to the occurrence of different impacts and their location relative to the cyclone track. Results indicate distinct variations in the spatial patterns of tornado, high wind, and flash flood impacts, particularly when comparing tropical cyclones of different sizes.
