Abstract
In this paper we attempt to calculate the maximum potential intensity of tropical cyclones following Holland’s model [7]. In order to establish this theory, background knowledge of tropical cyclone formation and atmospheric convection is first presented. Holland’s theory is solely based on thermodynamic considerations and mainly considers the eye (the center of the cyclone) and the eyewall. Although his approach can seem to overly simplify the numerous atmospheric parameters, like setting the relative humidity to 90% in the eyewall, and overlooking the internal processes of a tropical cyclone, we will see that it can somewhat accurately give a theoretical upper limit to the maximum intensity a cyclone can develop. The model only takes the surface parameters (the sea surface temperature, the surface pressure) and a single temperature sounding to represent the environment. The model has though one major flaw being that for a relatively high surface temperature that is effectively observed, it overestimates a little too much ( up to three times) the maximum wind speed observed compared to previous models.
