Explain the term absolute vorticity in a real-life context, such as a spinning ice skater. In your description, include the terms relative vorticity and Earth’s vorticity.?

What will be the ideal response?


ANSWER: ?Answers may vary. Watching an ice skater spin counterclockwise on a frozen lake, the ice skater possesses positive relative vorticity. If you could suddenly leave Earth and watch the same spinning skater from space, you would see the ice skater spinning on a rotating platform—Earth. The combination of the skater spinning about her vertical axis (her relative vorticity) plus the small spin imparted to her from the spinning earth (Earth’s vorticity) yields the absolute vorticity of the skater.
