The purpose of this study is to investigate how the 'mechanical efficiency' of tropical cyclones varies with sea surface temperature. This matters because the conceptualization of the tropical cyclone as a heat engine implies that the kinetic energy of its wind field is generated at this efficiency. The mechanical efficiency may be affected by changes in climate. Our results demonstrate that the mechanical efficiency decreases at ?2.1% K?1 with sea surface temperature, and in particular highlight the important role of moisture in this result.</p>
