Question

e. Un the same sheet of paper, sketch a cool-summer/warm-winter configuration for the Northern Hemisphere. Label appropriate the North Pole NP and label the two Earths that are 6 months apart with cool summer and warm winter as 19. Use Figure 15.9a to answer the following questions: (with wavelengths a. More than 80% of radiation fromthe sun is what two types of radiation? b. What type of energy is reradiated (not reflected) from the Earth's surface (Earth's surface spectrum)? c. What is Earth's peak surface radiation wavelength? ranging trom to_microns) and 3. The climate system has a number of different feedbacks, both positive and negative, and they are far too complex t go into all of them here. However, the ice albedo effect is very easy to understand. a. Does clean ice have a high or a low albedo? h It climate cools and glaciers grow, will Earth's albedo increase or decrease?

Explanation / Answer

19.a) more than 80% of radiation from the sun is UV( ultra violet ) radiation and visible radiation with wavelengths ranging from 0.001 to 0.4 microns( UV) and 0.4 to 0.7 microns( visible)

B. The type of energy reradiated from the earth's surface is infra red( relatively long wavelentgh)

C. Earth's peak surface radiation has a wavelentgh of 9.66 microns which lies in infra red region.

Clean ice have a high albedo.

If climate cools and glaciers grow, then earth's albedo will increase.
