Well, I believe in calculus, so I guess I have no choice but to believe in the Coriolis force, which is by no means a mysterious natural phenomenon but is simply the result of looking at motion from a certain viewpoint.

--- Quote ---I mean, if you believe in that, you believe in a RE because the effect can't apply on a FE.

Not really.  The Coriolis force is not a physical force; it has nothing to do with the shape of the Earth.

--- Quote ---I suggest you to travel to the Southern Hemisphere and feel the Coriolis effect on your own body,

What?

The Coriolis effect has everything to do with the shape of the Earth. Well, the shape and the spin of the Earth. It wouldn't exist the way it does IF they Earth was flat.

So if you believe in the Coriolis effect, you must necassarily believe in a round Earth.

Wind... Or you could perhaps sit in a plane and watch a typhoon on the southern hemisphere. Then go to the northern hemisphere and watch a hurricane there.
The whole point of this? To see the coriolis effect in work. And since the coriolis effect only is viable on a round Earth, you must necassarily believe in a round Earth.

You just admited that the Coriolis effect exists. So how does the Coriolis effect work in the FE model ?

I see.  You are referring to the Coriolis effect as it pertains to weather systems.  In fact, the Coriolis force is more general than that and applies to motion in any rotating system, regardless of the shape of that system.  This fact is discussed extensively on these forums, and probably quite a bit in this very thread.

Whether the Earth is flat or not has little to do with whether there is a Coriolis force acting on weather systems; the shape of the Earth will only change the way in which such a force varies with latitude.

Additionally, if I were to go and experience wind, as you say, it would be illogical in the extreme for me to conclude that it must be the Coriolis force causing the wind, even if the wind is incredibly powerful.  I may be very impressed by the strength of the wind, but I realize it does not add to the strength of your argument.

I have no idea where you are leading to with this, it just seems like you talk you way out of it rather than disproving it. I'm not going to respond to this since it's not the direction/purpose of this thread. Keep it on-topic.

I think you know perfectly fine which Coriolis effect I'm talking about. I'm talking about the effect we experience on this Earth where lowpressures on the southern hemisphere turn clockwise and counterclockwise on the northern hemisphere.

Now, on a flat Earth they wouldn't be turning like this. Why? Well, if the disk was somehow spinning, all lowpressures would only turn 1 way. And if the Earth was flat, storms and hurricanes would have no difficulty passing over equator since there is a Coriolis effect there, too, something which the RE doesn't have (coriolis near equator).

Unless you can find a perfectly valid arguement countering this, then I see  no reason to talk about everything else.

Since I am discussing the Coriolis force, it would appear that I am on topic.

There is only one Coriolis force.  It is a fictitious force which observers in rotating reference frames observe acting upon objects that move closer to or farther from the axis of rotation; it is to conservation of angular momentum what the centrifugal force is to conservation of linear momentum.

RE meteorologists claim that this force is responsible for the effect you are describing, namely, the alleged counterrotation of large storm systems in different hemispheres (sic).  Obviously, FEers must either claim that this counterrotation phenomena is caused by different principles, or that it does not exist altogether.  As I stated, other principles by which counterrotation might occur in the different hemispheres (sic) have been discussed extensively on this website.

In other words, my "valid argument" is that your question about how the Coriolis effect works in a flat Earth is loaded and equivocative.  In a flat Earth, the Coriolis force has nothing to do with counterrotating storms, which is what you are really asking about (and mislabelling as "the Coriolis effect").

Is that clearer?
