Maximum Potential Intensity (MPI) Theory Emanuel (1995), Bister and Emanuel (1998) upper bound on tropical cyclone wind speed: - See-surface temperature - Mean outflow temperature (close to tropopause temperature) - bulk surface exchange coefficients for heat and momentum -convective available potential energy of boundary layer air at the radius of maximum wind -convective available potential energy of surface saturated air at the radius of maximum wind
Maximum Monthly Emanuel’s Potential Intensity (MPI), m/s Theoretical estimate of the maximum sustained wind in a developed hurricane Computed from SP-CAM monthly climatology PETM (55 MY ago) Present m/s Despite much warmer tropical SSTs (by 10 o C!), hurricanes during PETM were probably not stronger that today’s hurricanes; maybe even slightly weaker!
