Uncertainties in estimating the effect of climate change on 100-year return value for significant wave height
Kevin Ewans, Philip Jonathan
Estimating climate effects on future ocean storm severity is plagued by large uncertainties, yet for safe design and operation of offshore structures, best possible estimates of cl…
Extremal Characteristics of Conditional Models
Stan Tendijck, Jonathan Tawn, Philip Jonathan
Conditionally specified models are often used to describe complex multivariate data. Such models assume implicit structures on the extremes. So far, no methodology exists for calcu…
Statistical estimation of spatial wave extremes for tropical cyclones from small data samples: validation of the STM-E approach using long-term synthetic cyclone data for the Caribbean Sea
Ryota Wada, Jeremy Rohmer, Yann Krien +1
Occurrences of tropical cyclones at a location are rare, and for many locations, only short periods of observations or hindcasts are available. Hence, estimation of return values (…
A multivariate pseudo-likelihood approach to estimating directional ocean wave models
Jake P. Grainger, Adam M. Sykulski, Kevin Ewans +2
Ocean buoy data in the form of high frequency multivariate time series are routinely recorded at many locations in the world's oceans. Such data can be used to characterise the oce…
Multivariate spatial conditional extremes for extreme ocean environments
Rob Shooter, Emma Ross, Agustinus Ribal +2
The joint extremal spatial dependence of wind speed and significant wave height in the North East Atlantic is quantified using Metop satellite scatterometer and hindcast observatio…
A penalised piecewise-linear model for non-stationary extreme value analysis of peaks over threshold
Anna Maria Barlow, Ed Mackay, Emma Eastoe +1
Metocean extremes often vary systematically with covariates such as direction and season. In this work, we present non-stationary models for the size and rate of occurrence of peak…
