Tropical cyclone momentum and energy fluxes
Many modeling studies of tropical cyclones use the bulk aerodynamic formulae to determine angular momentum and enthalpy fluxes at the sea surface. These results show that the intensification of a hurricane is very sensitive to the values of the coefficients defined in these formulae (Emanuel, …

Tropical Cyclone Risk Assessment Using Statistical Models
Tropical cyclones (TC) in the western North Pacific (WNP) pose a serious threat to the coastal regions of Eastern Asia when they make landfall. The limited amount of observational data and the high computational cost of running TC-permitting dynamical models indicate a need for statistical models …

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 …

Tropical Cyclone Hazards in Relation to Propagation Speed
… important to study the characteristics of tropical cyclones that can impact the coast. A recent study shows that the propagation speed of tropical cyclones has slowed over the past 60 years, which can lead to greater accumulation of precipitation and greater storm surge impacts. The study …

Incorporation of tropical cyclone avoidance into automated ship scheduling
… 45 days in advance to meet that demand. Tropical cyclones (TCs) frequently disrupt these plans, requiring diversions and inefficient steaming speeds. We evaluate the impact of adding anticipated TC positions in an operational planning tool called the Replenishment At Sea Planner. Various …

Tropical cyclone preparedness and response : opportunities for operations research
… response community by looking at two recent tropical storm disasters; tropical cyclone Yemyin in Pakistan, June 2007 and super typhoon Durian in the Philippines, Nov 2006. The case studies are used to highlight three common problem areas; determining the scope of the disaster, agency …

Tropical cyclone precipitation risk in the Southern United States
… algorithm that is used to simulate longterm tropical cyclone precipitation (TCP) climatology throughout the southeastern United States. The TCP climatology is based on a fleet of synthetic tropical cyclones developed using National Center for Atmospheric Research/National Centers for …

Characterization of the role of precipitation in tropical cyclone intensification
Tropical cyclone (TC) intensity prediction remains a primary challenge facing the tropical meteorology community. A host of widely varying intensification paradigms have been put forth in recent decades associated with various dynamic or thermodynamic mechanisms. The one constant across these …

Extratropical impacts on variability and prediction of tropical cyclone activity
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-04-06 without embargo terms

Tropical cyclone size in observations and in radiative-convective equilibrium
Tropical cyclone size remains an unsolved problem in tropical meteorology, yet size plays a significant role in the damage caused by tropical cyclones due to wind, storm surge, and inland freshwater flooding. This work explores size, defined as the radius of vanishing wind, in observations and at …

Estimating Atlantic Basin Tropical Cyclone Landfall Probability for the United States
… examines the historical record of hurricanes and tropical storms in the Atlantic Basin to determine the eventual landfall probability for the United States coastline based on the complete tracks of the storms. A spatial dimension is added so that the entire basin is evaluated to determine which …

The Role of Environmental Moisture on Tropical Cyclone Size and Structure
Tropical cyclone (TC) size is integral in determining the spatial extent of TC impacts and is influenced by environmental wind shear and the overall moisture environment. Since initial TC size is related to future TC size, research focused on understanding the influences of TC size away from land …

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 …

Formation and maintenance of tropical cyclone spiral bands in idealized numerical simulations
… bands are one of the most prominent features of tropical cyclones (TCs). These regions of clouds and rainfall are often the source of major TC hazards, such as inland flooding, mudslides, and tornadoes. Since the advent of radar technology, numerous ideas have been proposed to explain the …

A case study of the formation of an Eastern Pacific tropical cyclone
… study is performed to investigate the nature of tropical cyclogenesis in the eastern Pacific Ocean. Focus is given to the formation and development of the initial circulation which eventually intensified into Hurricane Fefa. Using satellite imagery, the author studies the development of …
