Extreme Weather & Ocean Hazards

(MAR-PPS595) -  Yannis Androulidakis

Descripción del Curso

The course includes the following topics:

  1. 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
  1. 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)
  1. 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
  1. 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)
  1. 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)
    • Influence on storms and heatwaves
    • Mediterranean regional focus: impact of teleconnections on Medicanes, droughts, and heatwaves
    • Response on biogeochemical processes and parameters
  1. Marine Heatwaves & Their Consequences
    • Causes and dynamics of oceanic heatwaves
    • Response on biogeochemical processes and parameters
    • Impact on marine ecosystems (coral bleaching, fishery collapses)
    • Long-term climate trends and marine heatwave prediction
    • Detection methods and analysis
  1. Extreme Wave Events
    • Analysis of extreme wave characteristics
    • Mechanisms behind rogue wave formation
    • Impacts on ships and offshore structures
    • Ocean wave forecasting techniques
  1. Coastal Erosion During Extreme Events
    • Interaction between storms, tides, and coastal geomorphology
    • Barrier islands and wetland loss due to extreme weather
    • Engineering solutions (seawalls, dune restoration, managed retreat, beach nourishment, NBS)
  1. Climate Change & Intensification of Ocean Hazards
    • Trends in storm intensity and frequency
    • Future projections of extreme weather events
    • Risk assessment and adaptation strategies
  1. Mitigation, Preparedness, and Policy
    • Early warning systems (e.g., NOAA, National Hurricane Center, Wave4us, Poseidon System, AEGIS+, tsunami warning networks)
    • Disaster management and emergency response
    • Coastal resilience planning and engineering solutions
    • Policy implications and international agreements on disaster mitigation
