Descripción del Curso
The course includes the following topics:
- Introduction to Extreme Ocean-Atmosphere Events
- Overview of extreme weather phenomena
- Ocean’s role in weather and climate systems
- Historical case studies of major ocean-related disasters
- Storms & Low Pressure Systems
- Formation, intensification, and movement
- The role of sea surface temperature (SST) and ocean heat content
- Tropical-like storms in the Mediterranean (Medicanes)
- Storm forecasting and modeling (numerical models, satellite observations)
- Impact on coastal communities and ecosystems (storm surges, flooding, erosion)
- Storm Surges & Coastal Flooding
- Physics of storm surges and wind-driven water movements
- Impact of sea level rise on storm surge risks
- Case studies (Hurricane Katrina, Typhoon Haiyan, Medicanes that affected Greek Seas and Coasts)
- Modeling and prediction of storm surges (presentation-training course of open-source 2-d model)
- Coastal Flooding
- Tsunamis
- Causes: seismic activity, underwater landslides, volcanic eruptions
- Wave dynamics and propagation
- Early warning systems and mitigation strategies
- Notable events (2004 Indian Ocean tsunami, 2011 Tōhoku tsunami, examples in the Greek Seas, example with Delft suite for tsunami modeling)
- Ocean-Atmosphere Teleconnections & Extreme Weather
- El Niño and La Niña effects on global weather
- Role of sea surface temperature (SST) anomalies in atmospheric circulation
- Tools and datasets used to identify teleconnections (reanalysis, satellite SSTs, indices)
