Kreuzsee
Kreuzsee near the Île de Ré
Cross sea refers to the phenomenon at sea that occurs when waves from different directions meet ( cross ). The superposition of these wave systems creates a complicated wave pattern that can be dangerous for shipping for two reasons: On the one hand, cross seas are very difficult to predict, so it is more difficult to approach each wave at the ideal angle. On the other hand, due to the superposition, individual waves can be significantly higher than would normally be expected, see interference .
Cross lakes can have various causes, for example:
- after a wind turn, the waves thrown up by the wind are superimposed on the old swell ,
- Waves generated by the wind are superimposed on a swell that has come from another sea area,
- Waves converge behind an obstacle (e.g. an island),
- Waves are thrown back from an obstacle (e.g. a pier or sheet pile wall ) and hit the waves.
When waves collide head-on, for example behind a rock in the surf, which shoot up violently when they collide, one also speaks of (torn) clapotis .
