Abstract Numerical and theoretical models of tropical cyclones indicate that the maximum wind speed in mature storms is sensitive to the ratio of the enthalpy and momentum surface exchange coefficients and that the spinup time of tropical cyclones varies inversely with the magnitude of these coefficients. At the same time, the Carnot cycle model developed by the author predicts that the central pressure of mature cyclones is independent of the magnitude of the exchange coefficients. The author… 
An Extended Model for the Potential Intensity of Tropical Cyclones
AbstractEmanuel’s theory of hurricane potential intensity (E-PI) makes use of the assumption that slantwise convective instability vanishes in a steady-state vortex of a tropical cyclone. In the
The understanding of the physical processes controlling tropical cyclone intensity has been an area of ongoing debate in recent years. Emanuel (1986) suggested that the intensification and
Sensitivity of Tropical Cyclone Simulations to Parametric Uncertainties in Air–Sea Fluxes and Implications for Parameter Estimation
AbstractTropical cyclones (TCs) are strongly influenced by fluxes of momentum and moist enthalpy across the air–sea interface. These fluxes cannot be resolved explicitly by current-generation
Impacts of Air–Sea Flux Parameterizations on the Intensity and Structure of Tropical Cyclones
AbstractFluxes of momentum and moist enthalpy across the air–sea interface are believed to be one of the most important factors in determining tropical cyclone intensity. Because these surface fluxes
An analytic model of tropical cyclone wind profiles
A physically based analytic model (λ model) is presented to describe the wind profile of tropical cyclones in terms of the pressure deficit and a single shape parameter (λ). To test the λ model, an
Sensitivity of tropical‐cyclone models to the surface drag coefficient
Motivated by recent developments in tropical‐cyclone dynamics, this paper re‐examines a basic aspect of tropical‐cyclone behaviour, namely, the sensitivity of tropical‐cyclone models to the surface
Evaluation of an Analytical Model for the Maximum Intensity of Tropical Cyclones
Several studies have shown that the intensity of numerically simulated tropical cyclones can exceed (by 50%) a theoretical upper limit. To investigate the cause, this study evaluates the underlying
Some Aspects of Hurricane Inner-Core Dynamics and Energetics
Abstract The energy cycle of the mature hurricane resides in the secondary circulation that passes through the storm’s eyewall. By equating the generation of energy in this cycle to boundary layer
Tropical cyclogenesis sensitivity to environmental parameters in radiative–convective equilibrium
In this study, the relationship between the likelihood of tropical cyclogenesis and external environmental forcings is explored in the simplest idealized modelling framework possible:
Ocean Effects on Tropical Cyclone Intensification and Inner-Core Asymmetries
Abstract The interaction between a tropical cyclone and the ocean is investigated using a minimal three-dimensional tropical cyclone model coupled with a two-layer ocean model. Two representations
