Statistical modelling of extreme ocean climate with incorporation of storm clustering

A 30-year time series of ocean observations from Australia's eastern and southern coast, focusing on storm clustering. The dataset was developed by the Bushfire and Natural Hazards CRC Project and involves statistical modelling of storm events. It includes extracted storm event data based on significant wave height thresholds and incorporates variables like wave period, direction, duration, and storm surge.

Use Cases

• Modeling coastal erosion risk based on clustered storm events described in the methodology
• Estimating storm event frequency and intensity using non-homogenous Poisson process models mentioned in the description
• Analyzing joint dependencies between storm magnitude statistics using Copula functions referenced in the study
• Assessing the impact of anti-clustering storm timing on coastal infrastructure resilience

Strengths

• Based on a 30-year time series of observations, providing a long-term climate context
• Uses a peaks-over-threshold approach with a defined 95% exceedance quantile (2.93 m) for event extraction
• Methodology includes manual validation against sea-level pressure data to ensure statistical independence 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 specific study site on the central coast of New South Wales
