Seiches are often imperceptible to the naked eye, and observers in boats on the surface may not notice that a seiche is occurring due to the extremely long periods. The effect is caused by resonances in a body of water that has been disturbed by one or more factors, most often meteorological effects (wind and atmospheric pressure variations), seismic activity, or tsunamis.

Webof the Kelvin wave over the Rossby radius,L R = gH f. To determine if the bay will show rotational effects and the decay of the tide away from the coast, we calculate the deformation radius relative to the wide of the bay. For instance, if the bay were 40 m and we are at 45N, then the deformation radius would be about 400 km. Thus, the bay would WebThe storm generated wind speeds of up to 60 miles per hour and sent a seiche toward Michigan City, Indiana. A 5.5- to 6-foot wave reached shore there at 8:10 a.m. and was reflected back across southern Lake Michigan, heading northwest toward Chicago.
