{'southern hemisphere': [0, 0, 2, 2], 'wind': [1, 0, 1, 2], 'earth': [0, 1, 1, 1], 'magnetic field': [0, 0, 0, 6], 'rotation': [1, 0, 0, 2], 'pressure': [0, 0, 0, 1]}
The rotation of the Earth causes the Coriolis effect, which is responsible for the deflection of winds towards the left in the Southern Hemisphere. The Coriolis effect is caused by the rotation of the Earth on its axis, which creates a centrifugal force that deflects moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The deflection of the winds is also affected by the pressure gradient force, which is responsible for the movement of air from high-pressure areas to low-pressure areas. The combination of the Coriolis effect and the pressure gradient force determines the direction and speed of the winds in different regions.
