INTRODUCTION: Wave breaking plays an important role in air-sea interaction processes that affect the world's climate and the cycle of greenhouse gases in Earth's atmosphere. Over many decades, wave breaking is assumed to be spectrally broadbanded. Investigation of source function balance of short ocean waves, however, leads to the conclusion that dissipation function displays a quasi-singularity behavior. In other words, the spectral property of wave breaking is localized in wave-number, ...
