What is the minimum distance an object has to travel to be affected by the Coriolis effect?
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]
What else can I help you with?
What currents are influences by the Coriolis effect?
Surface Currents
Why did Gaspard Gustave Coriolis named his invention the Coriolis effect?
Gaspard Gustave Coriolis named his invention the Coriolis effect after himself because he was the first to mathematically describe the phenomenon in fluid dynamics. His work on the effect, which explains the deflection of moving objects on a rotating planet, has since become a fundamental concept in meteorology and oceanography.
A sentence with coriolis effect?
The Coriolis effect causes moving objects on Earth, such as air currents and ocean currents, to appear to curve due to the rotation of the Earth.
What apparent curving of the paths of winds and ocean currents is the result of the rotation of the earth?
The apparent curving is known as the Coriolis effect. It causes moving air and water to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Earth's rotation. This effect influences the direction of winds and ocean currents on a global scale.
In the northern hemisphere the Coriolis effect causes winds to curve to the what?
The coriolis force is strongest at the poles
What is the minimum distance for the Coriolis effect to take place?
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 apparent curving of the winds is called?
the Coriolis effect
How will a wind blowing to the northern hemisphere be a affected by the coriolis effect?
it will bend to the west
How did the Coriolis effect influence winds?
it affected influince winds because coriolis can go out of control so it makes winds stronger.
How will a wind blowing to the south the northern hemisphere be affected by the Coriolis effect?
It will bend to the southwest.
How will a wind blowing to the south in the northern hemisphere affected by the Coriolis effect?
It will bend to the southwest.
How will a wind blowing to the the south in the northern hemisphere be affected by the coriolis effect?
it will bend to the west
How will a wind blowing to the north in the northern hemisphere is affected by coriolis effect?
It will bend to the east
How will a wind blowing to to the south in the northern hemisphere be affected by the Coriolis effect?
it will bend to the west
What currents are influences by the Coriolis effect?
Surface Currents
How will a wind blowing to the north in the Northern Hemisphere be affected by the Coriolis effect?
The Coriolis effect will cause the wind to deflect to the right in the Northern Hemisphere. So, a wind blowing to the north in the Northern Hemisphere will be deflected to the east due to the Coriolis effect.
What apparent shift in wind direction that is caused by the earth rotation?
Coriolis effect
