12-14: Equations of Motion Flashcards
1
Q
Vorticity
A
A measure of a particle’s spin about its axis
- Proportional to Angular momentum
Right Hand Rule!
-
Negative Vorticity
- Thumb down
-
Positive Vorticity
- Thumb up
2
Q
Friction
A
Three frictional force effects:
- Wind establishes waves/currents
- Exchange of KE between water parcels
- Convert KE into heat energy
As Currents become larger, so does friction force
3
Q
Friction - Eddy Viscosity
A
We can relate eddy viscosity to molecular viscosity
4
Q
Friction - Wind Stress (tau)
A
Friction between the interface of wind and ocean surfaces creates waves and currents.
The absolute magnitude of wind stress is proportional to the square of wind velocity
