Coriolis effect discrepancy. How to deduce the direction of the effect?

That means from the perspective of the equator to the north pole, it is rotating clockwise That's the part you got wrong. As seen from the Equator (as any other point on the Earth), the North pole is ...

Impossible or improbable? Hurricane crossing the equator

The Coriolis effect is necessary for FORMATION but NOT for MAINTENANCE of a tropical cyclone. Once formed, in a full-fledged tropical cyclone of hurricane intensity the wind balance is cyclostrophic,...

ocean current frequency

Ocean currents can be described as flow oscillations that are forced at different frequencies. In the absence of any external forces (wind, friction), the resulting flow is the inertial motion, which ...

If a prevailing wind traveled due east in the Northern Hemisphere, would the Coriolis Effect act on the water?

The Coriolis Effect occurs in all directions equally, even straight zonal (east-west) winds. Many indeed struggle with this idea - this Physics SE question has a fair explanation as to why. As ...

How does the Coriolis effect affect rivers and estuaries

The effects of Coriolis in rivers and estuaries are more subtle than in the open ocean. Coriolis tends to be a second or third order process in fast-moving and relatively small systems like rivers. ...

Does the Coriolis Effect affect a wind from East to West?

There have been a number of answers here that answer slightly different questions. As I understand it the question is "Why does the Coriolis force apply to objects (or air parcels) moving east and ...

Why is the pressure on the poles higher in Summer and lower in Winter?

My answer will only relate to the question in the title: Why is pressure on the poles higher in summer and lower in winter? Due to the axis tilt of the earth the winter hemisphere gets less heated by ...

Beta plane approximation: variation of Coriolis parameter

The Beta effect describes how the Coriolis force affects fluid motion depending on spatial changes due to the curvature of the Earth. In other words, it describes the variation of the Coriolis ...

How is centrifugal force identified in equations of fluid motion in the rotating reference system of earth?

I wonder why there is no centrifugal force, however, the apparent force in a rotating system should be the sum of Coriolis and centrifugal force. There is a centrifugal acceleration in those ...

Does the Coriolis Effect affect a wind from East to West?

First forget about the cardinal directions and accept the next notions about the directions of forces relative to the air flow. The air parcel is affected by the pressure force towards the low ...

Does the Coriolis Effect affect a wind from East to West?

The full answer is that you're moving through the Ekman layer. In the upper atmosphere, away from the ground, the wind direction is such that the Coriolis force and the pressure gradient balance each ...

Coriolis effect discrepancy. How to deduce the direction of the effect?

It's been a while since I've thought about this... and every time it still does take some careful thinking through it all. But hopefully this can really help you get it put together! First: Yes the ...

If North America were in the southern hemisphere, would the mountains and high desert have to be -east- of Tornado Alley?

No, the mountains would still need to be west of tornado alley. It all starts with temperatures. You often hear the colloquial "warm\cold airmass battle" image. But more specifically, the vital ...

Can Coriolis Effect cancel itself?

In an idealised scenario (ie where the plane is flying due north or south at a and there are no other perturbations to its course apart from the Coriolis effect), yes. And I guess it would be the most ...

Is it possible to detect Coriolis effect using a Wind Rose?

Like many of the other questions I answer on Earth Science SE, the answer is complicated. Based on the principle of geostrophy, the Coriolis force will point to the right of the wind vector in the ...

Does the Coriolis Effect affect a wind from East to West?

You all got it wrong! Coriolis force has nothing to do with the centrifugal force. The main answer to the question why Coriolis doesn't apply in the East-West direction is that East-West direction is ...

Why does air moving from Equator to Poles deflect to right in Northern Hemisphere due to Coriolis Force?

Therefore, a wind flowing up will deflect to the left to meet the low pressure region, similarly, a wind flowing from North Pole to the point will deflect right since the point is moving faster than ...

Does the Coriolis Effect affect a wind from East to West?

The effect on air going east or west may get called Corioles effect and looks similar, but has an entirely different cause and is called the Eötvös effect. It is a true force, unlike Coriolis, (which ...
