The time, space and velocity scales are important in determining the importance of the Coriolis effect. Whether rotation is important in a system can be determined by its Rossby number, which is the ratio of the velocity, U, of a system to the product of the Coriolis parameter,, and the length scale, L, of the motion:.
The Rossby number is the ratio of inertial to Coriolis forces. A small Rossby number signifies a system which is strongly affected by Coriolis forces, and a large Rossby number signifies a system in which inertial forces dominate. For example, in tornadoes, the Rossby number is large, in low-pressure systems it is low and in oceanic systems it is around 1. As a result, in tornadoes the Coriolis force is negligible, and balance is between pressure and centrifugal forces. In low-pressure systems, centrifugal force is negligible and balance is between Coriolis and pressure forces. In the oceans all three forces are comparable.[16]
An atmospheric system moving at U = 10 m/s occupying a spatial distance of L = 1,000 km (621 mi), has a Rossby number of approximately 0.1. A man playing catch may throw the ball at U = 30 m/s in a garden of length L = 50 m. The Rossby number in this case would be about = 6000. Needless to say, one does not worry about which hemisphere one is in when playing catch in the garden. However, an unguided missile obeys exactly the same physics as a Baseball, but may travel far enough and be in the air long enough to notice the effect of Coriolis. Long-range shells in the Northern Hemisphere landed close to, but to the right of, where they were aimed until this was noted. (Those fired in the Southern Hemisphere landed to the left.) In fact, it was this effect that first got the attention of Coriolis himself.[17][18][19]
Surface Currents
his name was coriolis ,so coriolis effect.
i learned Coriolis effect in school.
The Coriolis Effect.
The coriolis effect makes ocean currents move in a curved path.
Surface Currents
There really isn't one. The Coriolis effect has been demonstrated in tanks as small as a few feet across, provided that one waits long enough for residual currents from filling the tank to die down.
the Coriolis effect
it will bend to the west
it affected influince winds because coriolis can go out of control so it makes winds stronger.
It will bend to the southwest.
It will bend to the southwest.
it will bend to the west
it will bend to the west
It will bend to the east
