Rogue Waves
Context
Rogue waves, which are unusually large and unpredictable compared to surrounding waves, pose significant risks to ships, coastal infrastructure, and human safety. Despite their known dangers, forecasting rogue waves has historically been challenging and lacked effective methods. However, researchers have trained an AI programme to distinguish wave patterns that preceded rogue waves.
Understanding Rogue Waves
- Rogue waves typically occur in oceans, defying average sea state conditions.
- These waves can be twice the size of surrounding waves and often result from the convergence of distant swells or compression of ocean currents.
- Consequences: The unpredictability of rogue waves has resulted in numerous fatalities and ship sinkings.
Advancements Using AI
- Researchers have developed a breakthrough using artificial intelligence (AI) to predict rogue waves.
- The AI program analyzedand identified specific wave patterns preceding rogue waves, distinguishing them from regular wave patterns recorded during non-rogue wave periods.
- The AI achieved a prediction accuracy of approximately 75% for rogue waves one minute in advance and about 73% five minutes in advance.
- This capability was demonstrated across different buoy locations and depths, indicating potential universal applicability.
