**A climatology of hurricane maximum potential intensity in the Atlantic basin

A seven year period (1992-1998) of hurricane maximum potential intensity (MPI) in the Atlantic basin is examined using the thermodynamic method of Holland. The Holland approach assumes that the maximum achievable intensity is not limited by internal processes and detailed cyclone dynamics. Hence, it is possible to estimate the maximum potential intensity based on the thermodynamic energy of the environment, which is represented by an atmospheric temperature sounding, sea surface temperature (SST), and surface pressure.

The temperature soundings and surface pressures from the NCEP/NCAR Reanalysis data are used in conjunction with the Reynolds weekly SST data to produce the MPIs. Results show temporal and spatial patterns of maximum intensity which are consistent with climatological hurricane activity in the Atlantic. This preliminary finding suggests that the use of the Holland MPI routine with input from the NCEP/NCAR Reanalysis and Reynolds SST datasets provides a valid method for future studies on intraseasonal and interannual variability of tropical cyclone intensity in the Atlantic basin.
