﻿Exercise 17 Problems - Part I: Answers
1. The temperature contrast between the equator and the Arctic region is greatest in the winter, because the Arctic region is furthest away from the Sun during that time. 2. (a) The one region of the world where the hypothetical isotherm pattern is actually observed is in the Southern Hemisphere, starting at approximately 30° S. (b) The hypothetical pattern is seen here, because the oceanic and atmospheric circulations in this region constantly run from west to east with the West Wind Drift. This drift directly influences the temperatures in this region, and keeps this hypothetical pattern stable. 3. (a) The influence of cool ocean currents on coastal temperatures is more pronounced in the summer. (b) Cool currents deflect isotherms equatorward, whereas warm currents deflect them poleward (Hess, 2014, p 101). Cool currents produce the greatest isothermal bends in the warm season (Hess, 2014, p 101). 4. (a) Comparing the January map with the July map, the one region of the world that exhibits a large annual temperature range is the Eurasian continental mass. (b) Enormous seasonal variations in temperature occur in the interiors of high-latitude continents, and continental areas in general experience much greater ranges than do equivalent oceanic latitudes (Hess, 2014, p 103). (c) One region of the world that exhibits a small annual temperature range is the Southeastern Asian tropics. (d) This average temperature fluctuates only slightly from season to season in the tropics, particularly over tropical oceans (Hess, 2014, p 103). The areas that are closest to the equator will experience slight temperature ranges annually because they constantly receive the vertical rays of the Sun. Exercise 17 Problems – Part II: Answers

Starting in the west, point A, the actual 16°C isotherm dips just below the hypothetical position. This could possibly...
