Extreme Value Analysis of Rainfall Events Over the Kennedy Space Center Complex
… to determine the occurrence frequencies of extreme weather events has gained a lot of recent interest due to concerns about the potential regional impacts from global climate change. Extreme-value theory can quantify the return frequency of the most extreme events, using climatologically …

Wind pressure coefficients for gable roofs of intermediate slopes
… been obtained from the wind tunnel measurements. Extreme value analysis has been performed to establish the peak pressure coefficient values. This thesis presents a comparative study based on the experimental data, which consists of two parts. The first part includes the comparisons of the …

Extreme value theory: Applications to estimation of stochastic traffic capacity and statistical downscaling of precipitation extremes
<p>This work explores two applications of extreme value analysis. First, we apply EV techniques to traffic stream data to develop an accurate distribution of capacity. Data were collected by the NHDOT along Interstate I93, and two adjacent locations in Salem, NH were examined. Daily flow maxima …

Essays on Quantitative Risk Management
… management can be achieved by combining extreme value analysis to describe downside tail risk and dynamic copulas to model nonlinear dependence structures. Conditional Value-at-Risk is adopted as pertinent measure of downside tail risk for portfolio optimisation. Using both realised …

A contribution to risk-informed inspection and maintenance planning for unpiggable pipelines subject to internal corrosion
… planning. It also includes uncertainty analysis and lifecycle-cost optimization. An extreme value analysis is developed to model localized corrosion and microbiologically-influenced corrosion, which are the main causes of internal corrosion failure in pipelines. A method for decision …

Statistical methods for weather-related insurance claims
… losses, are rather rare and the statistical analysis is hence usually based on a low number of observations. Methods from extreme value theory consider the modelling of such events and may hence be beneficial. This thesis aims to develop statistical models for the relationship between …

Spectral properties of the random conductance model
… linked to the first eigenvectors and eigenvalues of its generator with zero Dirichlet boundary condition. This follows directly from the spectral decomposition of the associated heat equation. In this thesis, we study these first eigenvectors and eigenvalues when the underlying lattice is …

Statistical models for extreme weather events
Western Europe is typically prone to extreme weather events during the winter months, which typically take the form of windstorms or flooding. The storm Desmond brought strong winds and heavy rain to Ireland, northern England and Scotland in December 2015, resulting in an estimated $500 million …

Understanding Coastal and Inland Hydrometeorological Hazards Produced by Extratropical and Tropical Cyclones along the East Coast of the United States
… hazards. Through the use of observational and reanalysis data, the work herein utilizes a cyclone-hazard association algorithm and extreme value analysis to assess the extent, probabilities, and causes of hydrometeorological hazards.</p> <p>Chapter 2 examines the characteristics of ETCs and TCs …

Enhancement of the United States extreme wind database and implications for extreme wind climatology
… recent years to improve the characterization of extreme wind climatology in the contiguous United States, uncertainties still remain in its formal quantification. The importance of an accurate assessment of extreme wind climate is paramount, however, due to the outsized weight that the “basic …

Detection of long-range dependence : applications in climatology and hydrology
… waves that lead to food shortage, or the other extreme, floods that lead to severe damage. To prevent such catastrophic events, it is necessary to understand, and to be capable of characterising, nature's variability. Typically one aims to describe the underlying dynamics of geophysical records …

Feasibility study into accurately modelling sulphur dioxide flux in the lower atmosphere
… predictions. However, before carrying out such analysis, it is necessary to investigate the sources of variation. This thesis will consider the nature of the calculation of the sulphur dioxide flux, based on three simultaneous concentration measurements corrected for stability height. The need …

Methodology for development of drought Severity-Duration-Frequency (SDF) Curves
… across Victoria, Australia were selected for analysis. To achieve the above objective, the analysis was initially carried out to select the most applicable meteorological drought index for Victoria. This is important because to date, no drought indices are applied across Australia by any …
