Weather Theory and Principles

A common type of ground- or surface-based temperature inversion is that
produced by
.
1 - warm air being lifted rapidly aloft in the vicinity of mountainous
terrain.
2 - the movement of colder air over warm air, or the movement of warm
air under cold air.
3 - widespread sinking of air within a thick layer aloft resulting in
heating by compression.
4 - ground radiation on clear, cool nights when the wind is light.

The primary cause of all changes in the Earth's weather is
.
1 - variation of solar energy received by the Earth's regions.
2 - changes in air pressure over the Earth's surface.
3 - changes in air moisture content.
4 - movement of the air masses.

A characteristic of the stratosphere is
.
1 - visible moisture in the form of clouds and thunderstorms.
2 - an overall decrease of temperature with an increase in altitude.
3 - a relatively even base altitude of approximately 35,000 ft.
4 - relatively small changes in temperature with an increase in altitude.

Steady precipitation, in contrast to showers, preceding
a front is an indication of
.
1 - cumuliform clouds with moderate turbulence.
2 - stratiform clouds with moderate turbulence.
3 - cumuliform clouds with little or no turbulence.
4 - stratiform clouds with little or no turbulence.

The presence of ice pellets at the surface is evidence that
.
1 - there are thunderstorms in the area.
2 - a cold front has passed.
3 - there is freezing rain at a higher altitude.
4 - you can climb to a higher altitude without encountering
more than light icing.
