Kelvin wave

A Kelvin wave is a type of moving disturbance in the ocean or atmosphere that travels along a boundary, such as the coast or the equator. It combines gravity and Earth's rotation effects, causing a ripple or pulse that stays close to the boundary while moving forward. In oceans, Kelvin waves often occur during events like El Niño, affecting weather and sea conditions worldwide. They are important for transferring energy and influencing climate patterns, acting like a wave that holds its shape along a surface, moving water or air efficiently along boundaries.
