Midlevel ventilation's constraint on tropical cyclone intensity
… flux of low-entropy air into the inner core of a tropical cyclone (TC), is a hypothesized mechanism by which environmental vertical wind shear can constrain a TC's intensity. An idealized framework is developed to assess how ventilation affects TC intensity via two pathways: downdrafts outside the …

Feasibility of using cloud top altimetry for estimating tropical cyclone intensity estimation
… an accurate and reliable means of estimating the intensity of tropical cyclones. Professor Kerry A. Emanuel developed the theory that is under investigation. His theory aims to calculate the peak surface wind speed in hurricanes using only three parameters, all of which can be collected from …

Toward improved tropical cyclone intensity forecasts : probabilistic prediction, predictability, and the role of verification
… past two decades, deterministic predictions of tropical cyclone (TC) intensity consistently scored poorly in mean absolute error (MAE) verification, despite the concurrent advancement of TC modeling and observing capabilities. Given the importance of understanding this situation for the future …

Characteristics of tornadoes associated with land-falling Gulf Coast tropical cyclones
Tropical cyclone tornadoes are brief and often unpredictable events that can produce fatalities and create considerable economic loss. Given these uncertainties, it is important to understand the characteristics and factors that contribute to tornado formation within tropical cyclones. This thesis …

Secondary Eyewall Formation as a Response to Evolving Tropical Cyclone Wind Structure
… that form in many major (Category 3 or higher) tropical cyclones. They often contract, intensify, and replace the primary eyewall of the tropical cyclone in a process known as an eyewall replacement cycle. Eyewall replacement cycles have been linked to a spatial broadening of tropical cyclone …

The tropopause region thermal structure and tropical cyclones
… Second, what sets the thermodynamic limits of tropical cyclone intensity across the seasonal cycle? The link between these subjects is tropical cyclone outflow, which often reaches into the tropopause region, allowing the thermal structure there to impact tropical cyclone potential intensity. A …

On the climate variability of tropical cyclone potential intensity and Atlantic hurricane activity
… questions one needs to answer about a given tropical cyclone is how strong the winds generated by the event can become. From a climatological standpoint, it is critical to predict tropical cyclone activity, or the collective destructive potential of all tropical cyclones in a given basin and …

Sea Spray-Mediated Fluxes at Extreme Wind Speeds
Tropical cyclones are complex systems that are challenging to forecast and model. Since tropical cyclones are powered by the warm ocean surface, the accuracy of intensity forecasts depends heavily on the air-sea interaction scheme. However, at extreme wind speeds the air-sea transition layer …

Use of soft computing pattern recognition techniques to analyse tropical cyclones from meteorological satellite data
Tropical cyclones are potentially the most destructive of all natural meteorological hazards. When these cloud systems make landfall, they cause significant amounts of human death and injury as well as extensive damage to property, therefore reliable cyclone detection and classification form …

Multi-scale interactions leading to tropical cyclogenesis in sheared environments
To be, or not to be, that is the question of tropical cyclogenesis. Only a small fraction of tropical disturbances eventually develop into tropical cyclones (TCs). Accurate forecasts of tropical cyclogenesis are difficult because TC development involves a wide range of scales from the stochastic …
