Is there a table available for the maximum potential intensity of hurricanes?
This perhaps only indirectly addresses the question, but maybe it might be helpful. According to Kerry Emmanuel's book "Divine Wind", a hurricane can, in a sense, achieve super-Carnot efficiency without violating the Second Law of Thermodynamics. A hurricane's heat reservoir is the ocean surface at temperature Th and its cold reservoir is the tropopause at temperature Tc. Heat flow Q, mainly via water evaporating from the warm ocean and condensing in the cold upper troposphere is, according to the Carnot efficiency (Th - Tc)/Th, converted into work W as per W = Q(Th - Tc)/Th. But a hurricane's work output is the kinetic energy generation for its winds. With a hurricane in steady sate (constant wind speeds) kinetic energy generation is matched by frictional dissipation. Frictional dissipation of W into the hot reservoir reduces the net heat input required from the hot reservoir from Qh to Qh - W = Qc and raises the hurricane's efficiency to (Th - Tc)/Th X Qh/(Qh - W) = (Th - Tc)/Th X Qh/Qc = (Th - Tc)/Th X Th/Tc = (Th - Tc)/Tc. The Second Law of Thermodynamics is not violated because it allows work to be dissipated via friction as heat at any temperature --- at Th as well as at Tc. Of course the above assumes perfect or reversible operation. Like all real heat engines, hurricanes are imperfect. But perhaps it at least illustrates the point.
