Biography
Dr. Rafa Santana is a physical oceanographer at Earth Sciences New Zealand (formerly NIWA). His research focuses on the dynamics of ocean variability across temporal and spatial scales, with applications to wind waves, sea ice, extreme sea levels, and marine heatwaves. His methodologies include numerical modelling, data assimilation, multi-model ensembles, extreme value statistics, and coupled ocean-wave-sea ice simulations. He is actively involved in collaborative research with New Zealand universities and international partners.
Areas of expertise
- Extreme value analysis (GPD, joint probability approaches, ensemble forecasting)
- Ocean and wave modelling (coastal waves, sea surface temperature, extreme sea levels, sea ice dynamics)
- Coupled modelling (ocean–wave–sea ice systems)
- Climate variability and change impacts (marine heatwaves, sea-level rise, Antarctic sea ice decline)
- High-performance computing for large-scale simulations
Currently working on the following research projects
- Coastal hazard and extreme sea level assessment using joint probability and peaks-over-threshold approaches
- Development of coupled ocean–sea ice models for Antarctic climate applications
- Improving wave forecast skill through calibration using satellite data
- Integration of climate model projections into risk frameworks for aquaculture and coastal infrastructure
Recently Featured Work
Wave hazard research
Research Project
NIWA collects wave data, develops and verifies wave forecasting systems, and is developing and producing wave projections.
Storm surge and wave forecasting
Service
We combine capabilities in weather, wave, storm surge and tide forecasting with tide gauge observations.
