PROBLEM 1 (10)

Describe in no more than 100 words the climate of a specific location (city, town, region, state, or country) in the Southern Hemisphere that you would most like to visit. In describing the climate address the following: annual temperature range, diurnal temperature range, average temperature, average precipitation, and annual distribution of precipitation. Please feel free to consult various sources, i.e., books, web, etc., but make sure that your sources are appropriately cited (see below).

PROBLEM 2 (5, 5)

A standard pressure of 1013.25 mb is also known as 1 atmosphere (1 ATM).

  1. Look at Fig. 1.8 in Ahrens and determine at approximately what levels you would record a pressure of 0.5 ATM and 0.1 ATM.

  2. The surface air pressure on the planet Mars is about 0.007 ATM. If you were standing on Mars, the surface air pressure would be equivalent to a pressure observed at approximately what elevation in the earth's atmosphere?

PROBLEM 3 (5)

In northern latitudes, the oceans are warmer in summer than they are in winter. In which season do the oceans lose heat most rapidly to the atmosphere by conduction? Explain how you obtained your answer.

PROBLEM 4 (15)

Suppose that your average surface body temperature is 900F and that the surface area of your body is 1 m2. Suppose your friend has an average surface body temperature of 910F and that the surface area of his/her body is 0.8 m2. Which one of you is more radiant? That is, which one of you is emitting more radiant energy? (Hint: See the focus section on page 42 and don't forget to convert 0F to Kelvins.) Be sure to explain how you obtained your answer and show all work.
