How does the Coriolis effect explain Ekman transport?
Before answering the question, keep in mind that I am a second year Biology student, with no experience in studying Physics and a very basic understanding of Mathematics. Thus, I would prefer a ...

Why does air moving from Equator to Poles deflect to right in Northern Hemisphere due to Coriolis Force?
apologies if this is the wrong place to post this question in, but I am having a really hard time grasping Coriolis Effect.
My current understanding is that -
Let's say there's a point midway from ...

Rossby waves in the atmosphere
I have trouble understanding the Rossby waves in the atmosphere.
Sometimes they are said to be caused by the jets moving from west to east. But the phase velocity of the waves is in the west direction ...

How is centrifugal force identified in equations of fluid motion in the rotating reference system of earth?
I spent already days on the following: In one of my meteorology scripts the equations for conservation of momentum in the rotation reference system of earth are given by:
The apparent forces are in ...

(Why) is the thermohaline circulation not affected by the coriolis effect?
Why doesn't (e.g.) the equatorward North Atlantic Deep Water bend more to the west?
Is it maybe because the water tends to move relatively slowly and the magnitude of the Coriolis effect depends on ...

Is it possible to detect Coriolis effect using a Wind Rose?
I once learned in high school that the area where I used to live experiences the Coriolis effects of the air movement above the city. I never paid attention to this before, but I recently heard about ...

Why is the pressure on the poles higher in Summer and lower in Winter?
Just to give context, this was not my original question but one that I ended up stuck with while trying to find a cause for the following observation (which is almost universally true for temperate ...

Beta plane approximation: variation of Coriolis parameter
The Beta plane approximation put me in confusion.
Beta plane approximation explain me how the Coriolis parameter changes with latitude.
Beta parameter changes with the cos(latitude) but this is ...

Why an inertial gyro has a frequency and a geostrophic gyro does not?
Inertial flow is given by the balance between Coriolis and centrifugal forces. A geostrophic flow is given by a balance between Coriolis and the gradients of pressure. The frequency of the inertial ...

Why do Mediterranean main currents surrounding landmasses turn counter-clockwise?
At North Hemisphere, main superficial currents turn clock-wise, because of Coriolis Effect.
I would expect on Mediterranean Sea to have currents turning in the same sense, but, surrounding landmasses,...

Does the Coriolis Effect affect a wind from East to West?
I'm studying meteorology for a pilot license and there I was taught as a rule of thumb that wind at higher altitudes is approximately turned 30° clockwise to the wind on the surface due to the ...

Coriolis effect discrepancy. How to deduce the direction of the effect?
From what I understand (please correct me if I'm wrong), the Earth rotates counterclockwise as viewed from the north pole. That means from the perspective of the equator to the north pole, it is ...

If a prevailing wind traveled due east in the Northern Hemisphere, would the Coriolis Effect act on the water?
I am in a Marine Environmental Science II class, and we are discussing the Ekman Spiral. As I understand, the Coriolis Effect does not occur when whatever is observed does not change latitude. So, if ...

If North America were in the southern hemisphere, would the mountains and high desert have to be -east- of Tornado Alley?
I've been trying to collate the reasons why Tornado Alley in North America is what it is. So far, I have the following:
The continental landmass is in the mid-latitudes (where the polar jet has the ...

Can Coriolis Effect cancel itself?
Say a plane moves from 40° North to 40° South, and the plane flies in straight line without considering the Coriolis effect. Will it still reach the destination.
All I mean is whether the deflection ...

ocean current frequency
In this paper by Muller and Garrett it is stated:
It is a standard expectation that
currents in the ocean interior with frequencies
much less than the Coriolis
frequency will lead to an Ekman ...

In the South Atlantic and South-Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the reason? [duplicate]
Update:
Granted the question has been asked in different form; but the answer
still escapes me.
At one place I read that locations in question have low sea-surface
temperature. At ...

Why does Coriolis determine the rotation direction of a cyclone but not my drain?
It is a common misconception that Coriolis is responsible for the direction the water swirls down a toilet, tub or sink drain. E.g. does a toilet flush the other way in the southern hemisphere? (If ...

coriolis force in atmospheric/ocean modeling
The Coriolis force is not a real force, but depending on the reference system and how it does refer to an inertial system. Could this Coriolis force as widely used in atmospheric/climate modeling be ...

What do quasi-geostrophic and ageostrophic mean?
I know that geostrophic flow means straight wind flow that is balanced by the pressure gradient and Coriolis forces. But what do quasi-geostrophic and ageostrophic mean specifically?

Impossible or improbable? Hurricane crossing the equator
No known hurricane has ever crossed the equator. Hurricanes require the Coriolis force to develop and generally form at least 5° away from the equator since the Coriolis force is zero there.
