Rogue waves are unusually large and unexpected ocean waves that can be extremely dangerous. They can reach heights of over 30 meters (about 100 feet) and often appear suddenly, making them difficult to predict. These waves can occur due to various factors, including strong ocean currents, wind patterns, and the interaction of multiple smaller waves. Scientists study rogue waves to understand their formation and potential impact on ships and coastal areas. Research has shown that these waves can be caused by phenomena such as wave interference and nonlinear effects in the ocean. Understanding rogue waves is crucial for improving maritime safety and navigation.
