Storm events on Australia's eastern and southern coast are analyzed using a 30-year observational timeseries. The dataset includes multivariate statistics for each event, such as maximum significant wave height, duration, and peak storm surge. This work 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 clustered storm events.
- Estimating extreme wave height return periods using fitted Generalised Pareto distributions.
- Analyzing temporal dependencies between storm events using non-homogenous Poisson process models.
- Assessing joint probability of storm characteristics using Copula functions.
Strengths
- Based on a 30-year timeseries of observations.
- Storm events are extracted and manually validated against meteorological data.
- Multivariate analysis includes wave height, period, direction, duration, and storm surge.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to data_gov_au, focusing on central New South Wales.
