Exam 4: Moisture and Atmospheric Stability

All of the following are lifting mechanisms in the atmosphere EXCEPT:

Write a generalization relating air temperature and the amount of water vapor to saturate air.

The attractive forces between the hydrogen atoms in one water molecule and the oxygen atoms in another molecule are known as:

List and describe two of the four properties that make water a unique substance on earth.

The stability of the air layer close to the earth's surface can vary markedly. Much of this variation is caused by:

-Refer to the diagram of a simple parcel above. What would the mixing ratio be if the volume were to double?

$?=\frac{\text { mass of water vapor (grams) }}{\text { mass of dry air (kilograms) }}$ The formula shown above defines the humidity measure known as:

Which of the following is a good explanation for why dew tends to form in the grass at night?

The formation of frost is an example of deposition.

Write a statement relating the environmental lapse rate to stability.

Rain shadow deserts typically form on the windward sides of mountains.

$?=\frac{\text { mass of water vapor (grams) }}{\text { volume of air (cubic meters) }}$ The formula shown above defines the humidity measure known as:

In which phase do water molecules have the lowest kinetic energy?

As the temperature of air is reduced to its dew point, which of these is most likely to occur?

The property which primarily controls how much water can be present as a gas is:

List the primary factors that can increase the instability or stability of air.

Describe adiabatic temperature changes and explain why the wet adiabatic lapse rate of cooling is less than the dry adibatic rate.

What is the most frequent cause of the air becoming saturated?

A large negative environmental lapse rate would occur in a layer with:

More water is evaporated from the oceans than is returned to the oceans by precipitation.
