what are the two different types of turbulance?
- 1. mechanical turbulance
- 2. thermal turbulance
- -eddy motions created by obstructions.
- -creates a drag on the fow of air, one far greater than that caused by molecular viscosity.
effected by day time (uneven) surface heating.
the resistence of fluid flow.
the small-scale internal fluid friction that is due to the random motion of the molecules within a smooth flowing fluid, such as air.

what are the two types of eddies?
does the sea breeze blow from land to sea or from sea to land?
it blows from sea to land

in the afternoon
does a land breeze flow from the land twards water or from the water to land?
from land to water
do mountain breezes go up, or downhill?
downhill. valley breezes go uphill.
what is a chinook wind?
a warm dry wind that descends the eastern slope of the rocky mountains.
Are Katatabatic winds slow or fast moving?
what is the ideal setting for a katabatic wind?
an elevated plateau surrounded by mountains, with an opening that slopes rapidly downhill.
