Ships are afraid of big waves, so why are submarines not afraid of big waves when diving underwater?

The seemingly rough sea surface, but the seabed is "calm", so the submarine is not afraid of the wind and waves.

As we all know, there is no smoke without fire, and waves are mainly caused by the wind. The wind blows the sea surface, which makes the sea surface move periodically and causes waves to fluctuate. In stormy weather, every square meter area is impacted by several tons or even dozens of tons of force. In stormy weather, some ships are easily overturned by big waves, so in stormy weather, ships must return to Hong Kong to take shelter from the wind.

Submarines under the sea are much safer, because no matter how bad the sea conditions are, everything seems calm at a certain depth. Usually under the sea surface of 200 meters, it is rarely affected by waves. Therefore, although the sea is very rough, the submarine can move freely in the deep sea and is completely unaffected by the wind and waves.

The depth of submarine dive is usually more than 200 meters, so the submarine is absolutely safe in bad weather. Although submarines can resist more natural disasters, they are also very dangerous because submarines often dive to the bottom of the sea. In this case, their pressure will be greater, so it is more difficult to build submarines and there are more places to consider.

Finally, the submarine is absolutely safe in a stormy sea, because it can dive into a safe area where even a super storm can't affect it. So if you are lucky enough to take a submarine, don't worry about safety.
