Construction Of A Tropical Cyclone Size Dataset Using Retroactive Analysis Data With A Damage Application, Derek Trent Thompson

LSU Master's Theses

This thesis introduces a new tropical cyclone (TC) size dataset. Using the radius of the outermost closed isobar (ROCI) as the size metric of focus, a comprehensive record of TC size at landfall was constructed for tropical storms and hurricanes that made landfall in the United States along the East Coast and in the Gulf of Mexico. The ROCI information was derived from mean sea level pressure maps generated using the NCEP/NCAR Reanalysis I dataset over a 69-year period (1948 – 2016). Construction of the dataset involved using two methodologies, one based on hourly interpolated HURDAT2 best tracks and the …
