Flashcards in Chapter 7 Vocab Deck (13):
4 Forces that control the wind?
-Pressure Gradient Force
Area with a dimension of one unit, such as one square meter.
The rate at which pressure changes with distance
What are Turbulent Eddies?
Turbulent motions leading to mixing of air
What are the three turbulent Eddies?
Develops when air encounters obstructions associated with ground roughness.
Develops when the air near the earths surface is heated sufficiently during the day that it becomes unstable and rises to higher altitudes.
Exists when winds change over distance. Either increasing, or decreasing.
Occurs when wind speed changes rapidly with distance, typically with height.
Atmospheric layer in which friction is an important force.
When something is spinning.
When the upward pressure gradient force is exactly balances with gravity.
