Cyclone shelters and cyclone resilient design in coastal areas of Bangladesh
… countries that are most vulnerable to tropical cyclones. In recent decades, cyclone mitigations by the Government of Bangladesh and international organizations have greatly increased the coastal communities' resistance to cyclones. This thesis focuses on cyclone shelter programs, one of the most …

Cyclone climatology of the Great Lakes
Cyclones are an important feature of the Great Lakes region with significant impacts on ice cover, thermal structure, water quality, aquatic life, shipping, and shoreline property. For this research, a historical cyclone dataset was constructed for the period 1900 to 1990. This dataset was used to …

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, …

Fine coal beneficiation: comparison study of the separation efficiency of a dense medium cyclone and flat-bottom cyclone
… which classifier between a dense medium cyclone and a flat-bottom cyclone can optimally beneficiate the NGM-laden coal. A conventional hydrocyclone was modified into a flat-bottom cyclone with an extended cylindrical section and wide cone angle to promote the formation of an autogenous …

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
… 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 eyewall …

Tropical Cyclone Hazards in Relation to Propagation Speed
… 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 presented …

Evaluation of Methods for Improving Classifying Cyclone Performance
… of reducing bypass is to inject water into the cyclone apex. Unfortunately, existing water injection systems tend to substantially increase the particle cut size, which makes it unacceptable for ultrafine sizing applications. A new apex washing technology was developed to reduce the bypass of …

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 scenarios …

Tropical cyclone preparedness and response : opportunities for operations research
… 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 coordination, and relief logistics. The …

Tropical cyclone precipitation risk in the Southern United States
… 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 Environmental …

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 …

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
This dissertation 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 …
