The interactions between the atmosphere and the upper oceanic mixed layer are believed to be a major player in future tropical cyclone (TC) intensities and, ultimately, their lifecycle. The magnitude of this influence is still vague with respect to intensity and relative velocity. To develop a model of this interaction, we incorporate satellite altimetry, AVHRR SST, and Atlantic basin buoy profiles of temperature and salinity to derive a relationship for the dynamic height response of the 26 C isotherm (which is regarded as the lower bound for TC sustainment) as a function of intensity and TC forward motion. We consider data within 500km of selected cases from the 2003 - 2004 Atlantic tropical seasons.
