Which ingredient(s) do you think is (are) most likely missing in these
  cyclone-free areas? What will be an ideal response?

Question 2

If global warming is a real phenomenon, and ocean temperatures increase
  worldwide, how do you think this could affect the frequency, latitude
  range, and intensity of tropical cyclones. Justify your answer. What will be an ideal response?

Answer to Question 1

Answers will vary, but information presented here points to a combination of the lack of
a seasonal ITCZ and high vertical wind shear in these areas. There is some debate among
scientists as to the actual cause(s) of this phenomenon. (See www.aoml.noaa.gov/hrd/tcfaq/tcfaqHED.html
for additional information and discussion of this topic.)

Answer to Question 2

If ocean temperatures rise, and surface temperatures higher than 27 C are more
widespread, it is reasonable to predict that more tropical cyclones would form. These
would also reach higher latitudes and be of greater average intensity.
