21. That is why every research in physics is blocked, especially every research about Coriolis force . 22. The animation at the top of this article is a classic illustration of Coriolis force . 23. In that sense gravity is a force similar to centrifuge force or to Coriolis force . 24. In the non-inertial frame of the Earth, the fictitious Coriolis force is necessary to explain observations. 25. The local horizontal direction of the Coriolis force is thus \ Omega \ sin \ varphi. 26. Thus, the Coriolis force is always at an angle \ varphi with the local vertical direction. 27. :The Coriolis acceleration ( and hence the Coriolis force ) only exists when using polar co-ordinates. 28. The geostrophic wind component is the result of the balance between Coriolis force and pressure gradient force. 29. In fact the south flowing Agulhas Current swings away from the African coastline between about Coriolis forces . 30. Early in the 20th century, the term Coriolis force began to be used in connection with meteorology.
