Changing Climate

Most promising theory says that the Coriolis force appears only in specific dynamics (rotation balance) whatever reference frames. Had Riccioli discovered that?

While Kuhn and others explain how such paradigm shifts provoke resistance, scholars like Latour highlight the institutional anxiety they generate. The community’s admiration for Einstein is often hypocritical: his ideas were once resisted, and praising him now can disguise an ongoing reluctance.

What Makes the Foucault Pendulum Move among the Stars? - Science & Education Foucault’s pendulum exhibition in 1851 occurred in an era now known by development of the theorems of Coriolis and the formulation of dynamical meteorology by Ferrel. Yet today the behavior of the pen...

11/ The Foucault pendulum deflection might be a forced rotation involving a centripetal force, without any straight inertial motion in the background. This is consistent with a Coriolis force working.

link.springer.com/article/10.1...

10/ Are they really cases with a Coriolis force but without a centripetal force? Could not the Coriolis force be always the result of a centripetal force despite the says of G.Coriolis?

9/ If Coriolis force in geophysics is a residual of an imperfect centrifugal-centripetal balance that must be studied in the inertial frame of reference, what is such a balance?

8/ Does it mean that inertia is able to counter centripetal processes by responding with centrifugal processes?

7/ The Coriolis force in geophysics is consistent with a contest between a centripetal force and a common centrifugal force

journals.ametsoc.org/view/journal...

6/ We can derive the Coriolis force in the inertial frame of reference

If we smartly imagine a total centrifugal force, the inertial frame allows one to compute a vector being the anomaly of centrifugal force which acts exactly as the Coriolis force.

journals.ametsoc.org/view/journal...

5/ In applied physics, the Coriolis force is always associated to a centripetal force

This induces again very serious questions about what Coriolis equations are: does it really work for any external force?

4/ The Coriolis force in geophysics is associated to real forces having an oscillating work that make absolute kinetic energy oscillate

journals.ametsoc.org/view/journal...

This association induces very serious questions about what are Coriolis equations.

3/ The Coriolis force does not cause wide deflection in Earth dynamics

The Coriolis force, when alone, causes quick rotation, known as inertial oscillation (a few kilometers in ocean dynamics) and it does not relate simply to the size of the fluid meanders.

2/ The merry-go-round case is a bad illustration of the Coriolis force

If Coriolis equations were good, the deviation seen from the merry-go-round would be the sum of centrifugal and Coriolis forces and not the Coriolis force alone.

1/ The Coriolis force does not conserve absolute velocity.

It can be proven mathematically but simple reasoning is: if the Coriolis force conserves the relative velocity, it can not conserve the absolute velocity at the same time.

In this thread, you will understand what researchers "secretely" know about the Coriolis force and what revolution it could lead to

Coriolis academically is due to a rotating frame of reference. A most probable theory is that you must consider a centripetal force. If you walk on or keep a contact with a rotating platform, you get the centripetal and Coriolis forces. If you fly over it, you don't feel anything.

Coriolis force is still a research topic (read Anders Persson). I am convinced that only Persson's theory holds: Coriolis equations have a centripetal force in external forces. It would not work without a centripetal force. One must understand then what is a centripetal vs. centrifugal balance.

This is not Coriolis force what you and many others are showing. Coriolis force imposes much smaller circles and does not conserve absolute velocity. Coriolis force is still a research topic even if solutions already exist in the literature and it is now up to professors to read them.

Que ça plaise ou pas à l'OMS, aux médecins libéraux, aux "bobos", il faut arrêter ces idées d'air pur si on veut des solutions efficaces pour le climat.
La sécurité mondiale ne se résume pas à la médecine et à l'avis de l'OMS. Les temps changent. La planétologie doit avoir son mot à dire.

Au sujet du climat, qui était l'origine de ce compte :D
Je pense que la sensibilité au CO2 et aux aérosols est plus forte que celle de la moyenne CMIP3
C'est une bonne nouvelle pour les solutions efficaces à condition que les dirigeants arrêtent avec leur idées "bobos" d'air pur.

On retrouve la philosophie avancée par A. Persson pour la Terre (et pas que) : en conditions réelles, la force de Coriolis pousse "avec vigueur" à circulariser la vitesse relative, empêchant au possible une particule de s'éloigner d'un point collé à la plateforme tournante.

Cette expérience est très intéressante : elle montre comment la force de Coriolis veut circulariser la vitesse relative, ce que le teneur (qui initie la vitesse relative) a beaucoup de mal à empêcher, ce qui est dans le référentiel tournant une vraie force.

Des professeurs de science reconnus me répondent en privé sur la force de Coriolis en situation réelle (avec contact)

"je pense que la force centrifuge joue un rôle"
"quoi d'autre qu'une vraie force dans le référentiel tournant"

Ce soir à 12:00 le réacteur belge Tihange 1 sera mis à l’arrêt. Celui de Doel 2 suivra le 1er décembre. En l’espace de 5 ans la Belgique a donc perdu 3.8GW de capacité bas-carbone, malgré une population à 73% favorable à l’utilisation du nucléaire pour la production d’électricité.

A.Persson a consacré les dernières années de sa vie à écrire des textes percutants pour forcer une nouvelle réflexion sur la force de Coriolis terrestre, notamment les vraies forces sous-jascentes, et corriger l'enseignement. L'enseignement actuel trouble les étudiants, ce qui est bien une alerte !

Voici une exclusivité que m'a envoyée Uppsala University, Sweden. Un texte de 2020 de Anders Persson sur la force de Coriolis terrestre amenant l'idée de vraies forces sous-jascentes et le résultat : circularité (rappel à la position d'origine) et rigidité (exemple : colonne de Taylor)

Dans une situation de minimisation, il est logique que Fcor passe dans Fext :
On a dans le référentiel tournant :
ma = (Fcor+Fcentripete+Fautres)+Fcentrifuge
=> ma = Fcor+Fautres
Et dans le référentiel absolu :
ma = Fcor+Fcentripete+Fautres
(expliquant que certains ont étudié Fcor dans l'absolu)
