The breaker type is classified based on the unique thermal signatures of spilling and plunging breakers, shown in Figure 2, and using the semiThe four types of breaking waves WEBPlunging Waves Plunging waves are formed when the incoming swell hits a steep ocean floor or a sea bottom with sudden depth changes. As a result, the wave's crest curls over and explodes on the trough. The air under the lip of the wave is compressed, and a crashing sound is often heard. Plungers are more common in offshore wind conditions ScienceDirectBreaking waves - ScienceDirectWEBJan 1, 2020· Plunging breakers dissipate energy most rapidly and result in very rapid wave height decay; spilling breakers dissipate energy at a lower rate and result in slower rates of wave height decay; collapsing and surging breakers typically break on the beach directly, with a significant proportion of the energy reflected offshore rather than being ScienceDirectThree-dimensional Large Eddy Simulation of air - ScienceDirectWEBJun 1, 2006· In this current study, plunging breakers are considered.
