Question

Are submarines affected by rough weather when they are submerged?

Answer 1

If you took external forces such as wind, cross current and pressure cells out of the picture, the only energy in the water would be tidal and the rare subterranean disturbance like a land slide or earth quake.  These produce long gentle swells in deep water.  Even the Asian Tsunami of 2005 (?) only produced about a 6 inch swell in mid-ocean.  This has llittle or no affect on submarines.

Surface disturbance on the other hand produces short violent wave action which will affect a vessel within it's reach.  As previously stated at periscope or snorkel depth, this turbulance would affect the sub.  Fortunately modern submarines seldom have to expose them selves to surface conditions so it's not a serious issue.

I hope that helps.

Answer 2

Like the contributors above the deeper you go the less you feel. even near the surface the feeling is minimal but once a periscope is put up the waves will act on it and push the boat around. Also modern boats are so hydrodynamic that the cut through the water with ease when submerged unlike there old diesel counterparts with boat shaped hulls these were acted upon more than the newer subs.

Answer 3

As you go further below the surface the water is less affected by the waves and weather above,,just a few hundred feet down and the only things about are underwater currents,,you could have a hurricane raging above and 500 feet down you get hardly a thing,,

Answer 4

no they are not ....they can perform any duty that could be performed under calm conditions.

Answer 5

At periscope depth yes they are.  At 400 feet under the eye wall of a category 3 hurricane they rock gently.
