Please print out this homework assignment and complete it legibly.

1. For the following, state whether the description relates to weather or climate.

________________ The maximum temperature in New York City on Sunday was 80 F.

________________ The Amazon is a rainforest.

________________ The average high and low temperatures in Denver for September are 77.4 F and 47.3F, respectively

________________ Yesterday, it rained for 2 hours in Boulder.

2. The following figure represents the four layers in the atmosphere based on thermal structure. In each layer, draw the temperature change with height. Label each layer in the blanks to the right of the figure.

Top of the atmosphere

Surface

Use the following plot to answer questions 3 and 4.

3. Estimate the

a. Maximum temperature ________________

b. Minimum temperature _________________

c. Daily temperature range _________________

d. Daily mean temperature _________________

4. What is the approximate time of the

a. maximum temperature _________________

b. minimum temperature _________________

5. Convert the following temperatures:

a. 0C = __________ K

b. 212F = __________C

6. State whether latent heat is absorbed from or released to the atmosphere during the following processes.

a. Evaporation ________________

b. Melting ________________

c. Sublimation ________________

d. Deposition ________________

e. Freezing ________________

f. Condensation ________________

7. Put the following places in order from highest pressure at the surface to lowest pressure at the surface. Miami, Florida; the top of Mount Everest; Boulder, Colorado

Place with the highest surface pressure: _____________________

Place between the highest and lowest surface pressure: __________________

Place with the lowest surface pressure: _______________

8. Clouds that usually form east of a mountain range and sometimes look like a UFO are called ___________ clouds.

9. This is the point at which a rising air parcel stops following the dry adiabatic lapse rate and starts following the moist adiabatic lapse rate. Cloud bases begin to form at this level.

10. The temperature outside at the ground is 30 °C. An air parcel near the ground is picked up by the wind and forced up the slope of a mountain to an elevation of 1000 meters. The air parcel is adiabatic and it expanded and cooled on the way. The air parcel is also dry.

a. What is the new temperature of the air parcel at the top of the mountain? (Don’t forget units) _____________

b. If the air that was already at the top of the mountain was 15 °C, will the air parcel continue to rise or sink back to the ground? ____________

c. Was the atmosphere stable or unstable? _____________

11. Using the figure above, fill in the chart with the proper cloud names.
