# Are there rogue waves in the great lakes?

Freshwater Rogues Rogue waves can form in large bodies of freshwater as well as the ocean. One of the most famous shipwrecks of the 20th century, the Edmund Fitzgerald, was probably caused by at least one rogue wave on Lake Superior, part of the Great Lakes of North America.

Why are there so many waves in the Great Lakes?

A: There are other waves in the Great Lakes called seiches. These are caused by prolonged high winds that pile up water on one side of the lake, which then sloshes back and forth—like it would in a bathtub—and can oscillate for between two to 14 hours. The wave is the entire size of the lake or bay.

Which of the Great Lakes has the most dangerous waves?

Lake Michigan — long recognized as the deadliest of the Great Lakes — sees the most of these rogue waves each year.

Severe and deadly seiche events are rare on the Great Lakes. In the last century, about 10 major waves have hit the shores of the Great Lakes, but smaller anomalous waves occur much more frequently. Many of the deadliest have occurred on Lake Michigan, but Lakes Superior, Huron and Erie have also experienced them.

## Where do rogue waves occur the most?

One of the places rogue waves appear to happen most frequently is off the southeast coast of South Africa. A professor of applied mathematics at the University of Colorado at Boulder, Dr. Bengt Fornberg, studied this phenomenon with Marius Gerber of the University of Stellenbosch, South Africa.

What are rogue waves and how dangerous are they?

A ‘rogue wave’ is large, unexpected, and dangerous. When waves formed by a storm develop in a water current against the normal wave direction, an interaction can take place which results in a shortening of the wave frequency. This can cause the waves to dynamically join together, forming very big ‘rogue’ waves.

What is a rogue wave?

Rogue waves can form in large bodies of freshwater as well as the ocean. One of the most famous shipwrecks of the 20th century, the Edmund Fitzgerald, was probably caused by at least one rogue wave on Lake Superior, part of the Great Lakes of North America. Both the 222-meter (729-foot) ship and its crew of 29 were lost.

What are some facts about rogue waves?

These include:1933 – a U. 1966 – an Italian cruise ship was damaged when a rogue wave over 80 feet high smashed heavy glass out of its superstructure1978-a German barge carrier sank in the Atlantic ocean and the wreckage suggested that it encountered a huge wave., and more items.

When waves formed by a storm develop in a water current against the normal wave direction, an interaction can take place which results in a shortening of the wave frequency. This can cause the waves to dynamically join together, forming very big ‘rogue’ waves. The currents where these are sometimes seen are the Gulf Stream and Agulhas current.

They are both waves, they are formed completely differently, tsunamis are generally formed by a large sudden displacement of water, rogue waves are generally formed in areas of the ocean where the strong currents can run contrary to the wave direction for instance between Madagascar and South Africa.

“Rogue waves are a result of different swell interfering constructively, that is two wave fields combining such that two wave crests add up to produce a much taller wave. Another way they are caused is the interaction of waves with surface currents,” Stössel explains.

## Where do ‘freak waves’ happen?

These so-called “freak waves” are not confined to the Atlantic Ocean or North Sea. One of the places rogue waves appear to happen most frequently is off the southeast coast of South Africa.

## What is an Rogue?

Rogues, called ‘extreme storm waves‘ by scientists, are those waves which are greater than twice the size of surrounding waves, are very unpredictable, and often come unexpectedly from directions other than prevailing wind and waves.
