1
What is the Stefan-Boltzmann Law?
 
As the temperature of an object increases, more radiation is emitted each second
2
Wien's Displacement Law
 
As the temperature of a body increases, so does the proportion of shorter wavelenghts
3
Does light hit the Earth at equal angles?
 
No - at the equator it is hit right on, but not at the poles
4
When are we closest to the sun?
 
January
5
What kind of percipitation and temperature does leth have in the winter, and in the summer?
 
Low percip and temp in the winterHigher temp and percip in the summer
6
What kind of percipitation and temperature does van have in the winter, and in the summer?
 
High percipitation in the winter, low tempsHigh temp in the summer, low percipiation
7
Are winds stronger when the lines are closer together?
 
Yes.
8
What is the coriolis force?
 
Winds in the N. Hemi will be deflected to the RightWinds in the S. Hemi will be deflected to...
9
What is the friction force?
 
Surface roughness decrease wind speedReduces the impact of the inertial Coriolis force
10
What are anticyclones?
 
High pressure systems, with winds spiraling out of them clockwise
11
What are cyclones?
 
Low pressure systems, with winds spiraling into them counterclockwise. 
12
In a low pressure system, is air stable or unstable?
 
Unstable, with a tendency to converge and rise at the surface, and diverge aloft 
13
In a high pressure system, is air stable or unstable?
 
Stable, with a tendency to diverge and fall at the surface, and converge aloft.
14
Where does the jet stream form?
 
Alonf the Polar Front
15
Explain continentality
 
Temperature conditions more extreme - land warms and cools rapidly
16
Explain the conditions of marine areas.
 
Temperature conditions are more moderate, water warrms and cools slowly
17
During the day, does warm air flow from the land or the sea?
 
It flows from the land, and is cooled over the ocean.
18
During the night, does warm air flow from the land or the sea?
 
It flows from the sea, and is cooled over the land.
19
When do stable conditions exist?
 
When the ELR is to the right of the dry or moist adiabatic rate.
20
When do unstable conditions exist?
 
When the ELR is to the left of the dry or moist adiabatic rate.
