Using the terms pressure gradient and Coriolis be able to explain or draw the direction of wind movement. (Lecture 6, 3.3 b & c, 3.7, Wind pattern exercise).

Expert Solution
Concept and Principle:

The wind is generated due to uneven heating of Earth, and once generated the movement of the wind will depend on mainly two forces,

  1. Coriolis Force: A fictitious force that acts on objects that are moving in a rotating system. 
  2. Pressure Gradient force: Caused by difference in pressure across a surface.
