A 30-year timeseries of ocean observations from the eastern and southern coast of Australia underpins this statistical analysis of extreme storm events. The dataset includes multivariate summary statistics for storm events, such as maximum significant wave height, duration, and peak storm surge. This work is a key component of the Bushfire and Natural Hazards CRC Project Resilience to clustered disaster events on the coast.
Use Cases
- Modeling storm event frequency and intensity based on a peaks-over-threshold approach.
- Assessing coastal erosion risk from clustered storm events based on event duration and spacing.
- Fitting marginal distributions to storm variables like significant wave height using a Generalised Pareto distribution.
- Constructing joint dependency structures for storm magnitude statistics using Copula functions.
Strengths
- Based on a 30-year timeseries of ocean observations.
- Methodology involves manual validation of storm events against sea-level pressure data to ensure statistical independence.
- Statistical models account for sub-annual variations, temporal dependency, and finite event duration.
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 data_gov_au, focusing on the central coast of New South Wales.
