Exam 12: Moisture, Clouds, and Precipitation

________ is an indication of how near the air is to saturation rather than the actual quantity of water vapor in the air.

Match the items in the first column with the correct descriptions in the second column. A)The process of converting a liquid into a gas. B)The process by which water vapor changes directly to a solid. C)The general term for the amount of water vapor in air. D)The results of a situation where the environmental lapse rate is greater than the dry adiabatic rate. This occurs when air near the ground is significantly warmer (less dense)than the air aloft. E)This process results in the absorption of about 80 calories of latent heat per gram of water. F)The process by which water vapor changes to a liquid. G)The temperature at which saturation occurs. H)The part of the total atmospheric pressure that can be attributed to the water-vapor content. -1)deposition 2)condensation 3)melting 4)evaporation 5)humidity 6)vapor pressure 7)dew point 8)absolute instability

Examine the figure. Which process is illustrated?

Which of the following is NOT a physical mechanism that causes air to rise?

A temperature inversion occurs when ________.

Examine the photo. Now consider whether the following statement is true or false: "This is an example of glaze."

A wintertime form of precipitation that consists of small transparent or translucent ice particles is called ________.

________ is a type of fog that forms in valleys at night.

Clouds consist of ________.

A raindrop large enough to reach the ground without completely evaporating contains roughly 1 million times more water than a single cloud droplet.

Examine the photo. These balloons are rising because the ________ air inside the balloon is less dense than the surrounding air.

Compare and contrast absolute stability with absolute instability and conditional instability.

Glaze is a consequence of advective fog.

Why are hygroscopic nuclei important?

Relative humidity is usually expressed as a percent.

The opposite of sublimation is deposition.

Examine the figure. Now consider whether the following statement is true or false: "This is an example of a psychrometer."

The opposite of melting is condensation.

Cirrostratus clouds are associated with stormy weather.

The Bergeron process operates only in warm clouds.
