![]() ![]() ![]() When local winds interfere with these waves, they lose energy as they travel and dissipate just within minutes after they started. ![]() If not, the fatigue of trying to fight off and get out of two different currents will cause you to drown or die.īut as scary as it seems, you should know that this anomaly doesn’t last for long. If you’re lucky, you might get out unscathed. In the unfortunate event that you get caught in the middle of a square wave, the riptides will pull you out of the ocean, drag you under the water, and have the currents play ragdoll with you. What about humans? Although this rare phenomenon looks beautiful when seen from above, the danger it poses is located under the water’s surface. When this happens, freak waves form peaks that can reach up to 10 feet - a dangerous hazard that’s already caused multiple shipwrecks and boat capsizing all over the globe. In fact, most accidents happen when there’s a crossing sea or when the wind and sea are almost aligned.Īccording to research, colliding two-dimensional waves can cause the formation of wave packets that are three times more coherent than the amplitude of initial waves. Ships and small boats in the ocean are at more risk in the event of occurring rogue and square waves. You’ll see how these grid waves look like in the 0:15 to 0:20 mark of the video below. Since the seawater from the different conditions intersect but do not mix, cross-seas happen. For instance, it can happen in places near the coastline where there are two seas or two weather systems that come together in certain periods. Square waves occur because of varying conditions. You see, waves normally travel in parallel and break horizontally on shores, but in rare occasions that a cross-sea happens, the waves collide at right angles instead, forming the unique block pattern that can be seen above the water’s surface. As if there aren’t enough things yet to get scared about the ocean like the Great Whites and whirlpools, there’s a new kind of fear you can add to the list of what you should avoid in the water - square waves.Īlso referred to as cross-sea, these waves occur when two different swells from opposing directions meet. ![]()
