Australian Ocean Data Network provides a dataset for statistical modelling of extreme ocean climate, incorporating storm clustering. The data likely contains multivariate summary statistics for storm events, including maximum significant wave height, wave period, direction, duration, peak storm surge, and time of occurrence, extracted from a 30-year timeseries of observations. The study is part of the Bushfire and Natural Hazards CRC Project Resilience to clustered disaster events on the coast.
Use Cases
- Modeling coastal erosion risk based on storm clustering patterns described in the methodology
- Estimating storm event frequency and intensity using the non-homogenous Poisson process models mentioned
- Analyzing joint dependencies between storm magnitude statistics using Copula functions described
- Assessing the impact of anti-clustering on coastal hazard predictions as indicated by the results
Strengths
- Storm events are extracted from a 30-year timeseries of observations
- Events are defined using a peaks-over-threshold approach with a 95% exceedance quantile (2.93 m)
- Statistical models account for sub-annual variations, temporal dependency, and finite duration of events
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the single study site on the central coast of New South Wales
