Summary
| Description |
English: The rotating globe in the animation on the right represents the rotating Earth, and the black dot represents a balloon that is being swept along with air mass that has a velocity relative to the Earth's surface, and no atmospheric pressure gradient is present. The motion of the air mass is called 'inertial oscillations'.
In order to keep the number of animation-frames manageble, the following adjustment has been made: at 30 degrees latitude, the actual period of inertial oscillations is about 14 hours; in the animation the depicted period is exactly one half of the Earth's rotation period. Other than that the depicted motion is accurate: air mass moving dDue west is deviated to the north, due north is deviated to the east, due east is deviated to the south, due south is deviated to the west, and so on. |
