What would it be ike if two hurricanes collided together?

Question

Would their wind speeds add up along with the water? Ex. one hurricane is 75 m.p.h winds and the other is 115 m.p.h. winds. Would that make a hurricane with 190 m.p.h winds? I heard Tropical storm Gustav and hurricane Hanna are supposed to intersect each other. That would make a good hurricane video.

Answer 1

The hurricanes will probably merge overseas, but their energy and speed levels would not be added up exactly. As for your example the two hurricanes might add up to create a double hurricane with speeds ranging from 150 m.p.h. winds to even 200 m.p.h. winds.

This will only happen if the hurricanes are spinning in the same direction, though.

Can I have the best answer?

Answer 2

It is call the Fujiwhara Effect. http://www.easternuswx.com/bb/lofiversio... And it has happened. It mentions in the article that if one storm is larger than the other and a smaller storm is approaching and the two collide, the larger one "swallows" the smaller one up. I don't think it would add to their speed but the amount of rainfall and thunderstorm activity would most likely increase, which in turn can cause increased winds if other aspects of the weather are favorable.

Answer 3

this is what would happen.

first as they approach each other they would rotate around each other. then they would slowly head directly toward each. other. this has happened before, but what happens after this is petty rare. they then combine. the large storm would take the name of the stronger storm becuase the stronger storm would be the storm that eats the other, the storm would become much larger, but not nessesaraly both their strengths combined.

also although gustav and hanna are close to each other it probably wont intersect. gustav will impact the gulf coast way before hanna even threatens the usa.  

Answer 4

Gustav and Hanna may follow similar paths, but they will not collide intact.  If two hurricanes were to get too close to each other, what would happen is that one would eventually weaken and/or destroy the other. Hurricanes need to have a strong outflow out the tops of their circulations, in order to "exhaust" the air that is converging and rising from below. If two of them got too close to each other, the outflows would become restricted and one system's outflow will basically overpower the other, resulting in the weaker system being further weakened, or even destroyed. This has happened on occasion, usually when one system slowed down and the other closed the distance.  Indeed Hanna's  strengthening may be limited by the stronger outflow from Gustav.
