Title: What is an amphidromic point?

You lost me?  The Nordic maelstrom (Norway)
Or something else?

Maybe the question should be, in what way do your opinion differ from the physics defined?

No, the amphidromic point is a null of wave motion not currents. Currents do not circulate around an amphidromic point but across it.

What is an amphidromic point?
There is an introduction here (but ignore the last 2 minutes - he fantasises that tides are caused by undersea life...):
Note that Fremantle in Western Australia is an amphidromic point, which answers your previous question as to why Fremantle has periods with no tide.
Also note that there are different amphidromic points for the different drivers of tidal motion representing 1 tide per day or 2 tides per day. The total tidal range is due to the sum of these different tides around the various amphidromic points.

Currents do not circulate around an amphidromic point but across it.
Wikipedia: Sometimes these points are called tidal nodes: a tidal wave "runs through" this point around or counter-clockwise.

Tidal waves do not "run through" these points because they are nulls for the principle tidal constituent so there is almost no vertical movement from tidal action at these points.
They are not the centre of currents, whirlpools or maelstroms of any description.

The 'whirlpool theory of tides' is your construct. It is not a theory that is accepted by anybody else. It is nonsense.

It is not a question but a statement. It basicalky states that you are making things up that do not bear scrutiny.

This is a Google translate of the page you linked to:
“The amphidromic point (from the Greek ἀμφί - around and δρόμος - running) is the point in the ocean where the amplitude of the tidal wave is zero. The height of the tide increases with distance from the amphidromic point. Sometimes these points are called nodes of tides: a tidal wave "runs around" this point around by or counter-clockwise. At these points, the cotidal lines converge.

Amphidromic points arise due to interference of the primary tidal wave and its reflections from the shoreline and underwater obstacles. The Coriolis force also contributes.”

Please point to the section that says tidal wave ‘runs through’ this point or to the section that states that currents/whirlpools circulate around the point.

Yes, the video shows my point clearly. The tidal wave runs around the amphidromic point not through, and there are no whirlpools, just waves.

No
A whirlpool is a rotating current.
The wave going round a point is not the same thing.

Why are you unable to grasp this distinction?

No.
Not all bodies of water will have an amphidromic point.
Why do you assume that the Mediterranean sea has one?

Yes, I have noticed many errors. The one you repeat most often is the assertion that the tides are not driven (mainly) by the Moon.
You also seem to keep repeating the mistake that the Mediterranean sea has an amphidromic point.
There's also this error of yours@


No

The wave going round a point is not the same thing.

I can't change the fact  that the Moon drives the tide.
I can't change the tides in the Med.

Among the things I can't change is that there is no amphidromic point in the Med.
You can't change that either.
So, let's look at things we might change.

Can you change your belief that there is  an amphidromic point  in the Med?
Can you change your policy of not explaining why you think there should be one?

It doesn't matter much what you believe it means.

Why do you think the Med should have one?
