A scene from the Batman Begins movie opens with a strong breeze in the face of Bruce. As the scene progresses, you realize that
he is looking towards a glacier. It looks to be almost night. There is a type of wind that occurs in these situations. What is the best to describe that type of wind?
This breeze results from cold air flowing or running down a cold slope, such as the glacier in question. The air in contact with the glacier is colder and denser than the free air at the same altitude, causing the denser air to "fall" down the slope, and eventually reach Bruce in this opening scene.
