Extreme Ocean Storm Events on Australian Coasts with Clustering Analysis

A 30-year timeseries of storm observations from the eastern and southern coast of Australia, focusing on clustered events. The data includes multivariate statistics like maximum significant wave height, wave period, direction, duration, and storm surge. This dataset was produced by Geoscience Australia as part of the Bushfire and Natural Hazards CRC Project and was last updated in April 2026.

Use Cases

• Modeling the frequency and intensity of storm events based on a peaks-over-threshold approach.
• Assessing coastal erosion risk from clustered storm events using multivariate storm statistics.
• Fitting statistical distributions (e.g., Generalised Pareto, Pearson type 3) to storm magnitude variables.
• Constructing joint dependency structures for storm variables using Copula functions.

Strengths

• Based on a 30-year timeseries of observations, providing a long-term climate perspective.
• Includes multivariate storm statistics such as wave height, period, direction, duration, and surge.
• Applies statistical techniques like non-homogenous Poisson process models to account for event clustering.

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.
