The Emanuel’s hurricane potential intensity model was improved through the introduction of the thermoenergetics cycle of tropical cyclones as a generalized Carnot’s cycle,considering the presence of gradient wind imbalance at the top of the atmospheric boundary layer. The improved model overcomes the limitations concerning to the possible hurricanes superintensity. The calculations for the studied cases showed that for very intense hurricanes the simulated values of minimum pressure and maximum winds are very near to real values, also the locations in which the hurricanes reached maximum intensity shown a good coincidence with the areas predicted by the model, which in all cases correspond to the regions of higher sea surface temperature in their trajectories. The results evidenced a general good physical consistency of the model and an appropriate ability to calculate the maximum potentialhurricanes intensity.
