Question

. What are the global wind circulation patterns on hypothetical planet with no land (all ocean) and the same size as the earth but we assume: a) no rotation, b) rotation (with the same angular velocity of the earth) but no seasons, and c) rotation as in (b) but also tilt the axis to create seasons?

Answer 1

Answer: The global wind circulation patterns on hypothetical planet with no land (all ocean) and the same size as the earth are as follows.

A. The air on the equator is rising and goes towards the poles which replaces that air.

B. Coriolis effect produced through rotation of Earth. Southern hemisphere pushes air to the left. Northern hemisphere pushes air to the right, equal but opposite. Creates Polar and Hadley cell (interrupting the larger convection cell) High and Low Pressure is created.

C. Tilt of the axis , creates season, creates greater temporal difference in winter, creates bigger storms and bigger waves in the northern Hemisphere. Because of radiation movement of cold air to equator speeds up in the winter because of the greater difference in pressure.
