Infragravity waves are surface gravity wave s with frequency frequencies lower than the wind wave s consisting of both wind sea and swell ocean swell so corresponding with the part of the wave spectrum lower than the frequencies directly generated by forcing through the wind. Infragravity waves consist, among others, of long period oceanic waves generated along continental coastlines by nonlinear wave interactions of storm forced shoreward propagating Swell ocean ocean swells . These differ from normal oceanic gravity wave s, which are created by wind acting on the surface of the sea. Normal gravity waves typically have a frequency on the order of 50 hertz millihertz i.e., a period of 20 seconds . Interactions of these waves with coastlines filters out the frequencies with periods about 30 seconds, but nonlinear processes convert some of this energy to sub harmonics with periods ranging from 50 seconds 20 mHz to 350 seconds 3 mHz . Infragravity waves are these sub harmonics of the impinging gravity waves. ref name Bromirski2010 Cite journal last Bromirski first Peter D. coauthors Olga V. Sergienko and Douglas R.
