Meteorology · Waves — Rogue Waves
A 'rogue' (or freak) wave is best described as:
- AA wave found only in shallow harbors
- BA wave caused only by an undersea earthquake
- CThe normal significant wave height
- DAn exceptionally large wave, much higher than the surrounding sea state, often from the constructive superposition of wave trains✓ Correct
Explanation
Rogue waves are individual waves far larger than the prevailing significant wave height, arising from constructive interference of differing wave trains (sometimes focused by currents). Because they are steep and unexpected, they pose a serious threat even to large vessels.
