Document Summary
If the earth didn"t rotate, it would be easy for the global flow of air to balance the energy through a thermal circulation cell. Thermal convection would lead to formation of convection cell in each hemisphere. Surface wind in irvine would always blow from the north. But the earth does rotate and this really matter to the global. Coriolis force: the apparent force of being in a rotating world. Magnitude: depends upon the latitude and the speed of movement of the air parcel, the higher the latitude, the larger the coriolis force. Zero at the equator, maximum at the poles. The faster the speed, the larger the coriolis force. Direction: the coriolis force always acts at. Right angles to the direction of movement. To the right in the northern hemisphere. To the left in the southern hemisphere. A long range cannon wants to hit this target. Which is the best way to aim: a.
