| How wind-driven seiches occur. (NOAA) |
| A seiche (pronounced “saysh”) is a disturbance or water oscillation in an enclosed or semi-enclosed body of water like a lake. Seiches are often caused when strong winds push water from one end of the body of water to the other. They can also occur with strong changes in atmospheric pressure. Seiches are particularly common in Lake Erie, especially when strong winds blow from southwest to northeast. Seiche events now usually happen every 1-2 years on Lake Erie, causing localized flooding and intense erosion. Learn more about seiches here. |
