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 idealized full‐physics numerical model is employed to provide wind‐profile samples and also to show the influence of environmental temperature and the properties of initial vortices on tropical cyclone size. It is found that the λ model provides an accurate fit of the azimuthal wind profile at the… 
The low-level wind structure of tropical cyclones
The main effects of tropical cyclones include high winds, extensive storm surges, and widespread flooding. These main effects are all closely related to the low-level wind structure, the height of
An analytic model of the tropical cyclone outer size
There are simple conceptual models of tropical cyclone intensification and potential intensity. However, such a framework has been lacking to describe the evolution of the outer circulation. An
The Outer-Core Wind Structure of Tropical Cyclones
This paper presents a summary of several seminal observational and numerical studies on climatology and possible change mechanisms of the outer-core wind structure of a tropical cyclone (TC). This
The β-effect in tropical cyclones: impact on intensity and sensitivity to temperature
Tropical cyclones are large weather systems whose development is characterised by complex physical processes that are not yet fully understood. A better understanding of how cyclones work is vital to
The Impact of Storm-Induced SST Cooling on Storm Size and Destructiveness: Results from Atmosphere-Ocean Coupled Simulations
In this study, both an atmospheric model [Weather Research and Forecasting (WRF) model] and an atmosphere (WRF)-ocean (Princeton Ocean Model; POM) coupled model are used to simulate the tropical
Long Memory Impact of Ocean Mesoscale Temperature Anomalies on Tropical Cyclone Size
Mesoscale ocean temperature anomalies modify a tropical cyclone (TC). Through a modeling study we show that, while the maximum wind speed is rapidly restored after the TC passes a warm‐ or cold‐
Optimization of empirical typhoon model considering the difference of radius between pressure gradient and wind speed distributions
ABSTRACT This study proposes empirical relations for the ratio of the radius of maximum pressure gradient to the radius of maximum wind speed for the empirical typhoon model (ETM) based on the
Impact of Dry Midlevel Air on the Tropical Cyclone Outer Circulation
The impact of dry midlevel air on the outer circulation of tropical cyclones is investigated in idealized simulations with and without a moist envelope protecting the inner core. It is found that a
Tropical Cyclone Size Change under Ocean Warming and Associated Responses of Tropical Cyclone Destructiveness: Idealized Experiments
The power dissipation index (PDI), which is defined as the sum of the cube of tropical cyclone (TC) maximum wind speed during TC lifetime, is widely used to estimate the TC destructive potential.
Impact of wave whitecapping on land falling tropical cyclones
TLDR
It is shown here, for the first time, that in presence of continental shelf waves can cause substantial cooling of the sea surface, and including wave-ocean coupling is important to improve land falling tropical cyclone intensity predictions for the highly populated and vulnerable coasts.
