Nearly
twenty years ago, when I was a junior in high school, I took an interdisciplinary
course of Calculus and Physics. The class was held in the same room
with two different teachers teaching the math and physics. However,
there were times in the course, where the class had to solve problems
in Physics that required Calculus. The teacher that I had for Physics
was great in combining the two disciplines. Well, here in Kerry
Emanuel's Divine Wind, the MIT professor and researcher not only
combines the historic hurricanes of the past with the science that made
them memorable, but he also integrates cultural aspects of these storms
such as those produced in paintings, sculpture, poetry, and music.
This interdisciplinary
approach to the subject of hurricanes in this book is done in such a
way that the reader maintains his or her interest in the material, and
wants to keep on reading more. Emanuel, who has written many research
papers on the science, particularly the thermodynamics of these monsters
of the sea, can get very heavily involved with the math and physics.
Realizing that, and the limited capacity some of the readers may have
toward those areas, he tries to not only make it as simple as possible,
but he does what all good teachers should do, and that is give us a
break for a bit by branching of into the history and culture surrounding
these storms. The book was divided up into thirty-two chapters with
several appendices. Those thirty-two chapters were effectively divided
up between the math and science behind tropical cyclones, historic storms,
breakthroughs in meteorology, or how ancient civilizations such as the
Mayans, Aztecs, and early inhabitants of the Caribbean interpreted these
tropical menaces.
Emanuel,
who has been noted recently as suggesting
there is a link between global warming, particularly in the oceans
and the increased number of intense hurricanes, goes from explaining
the thermodynamics of a hurricane's heat engine in one chapter, to explaining
how that heat engine behind in say a classic hurricane such as the Labor
Day Hurricane of 1935. So, like in my interdisciplinary Physics
and Calculus class junior year, there is a combined theoretical and
applied approach used in this book. Emanuel even goes further by discussing
the social impacts and aftermath of these storms, and not only for those
that have occurred in U.S. History such as Hurricane
Andrew, but also those storms such as the Great
Bhola Cyclone of November, 1970 that killed between 300,000 to 500,000
people in what became Bangladesh. For instance, I learned in my reading
that the cyclone that hit East Pakistan at that time, created tremendous
political problems, and ultimately a Civil
War that resulted in Bangladesh gaining its independence.
Interspersed between
these lessons of both history and science would be poems, songs, excerpts
from literary works, photos of drawings, paintings, and sculptures devoted
to hurricanes. Emanuel points out that the ancient civilizations may
have been more advanced on this particular subject than we think. He
proves this by pointing out the similarities between the likeness of
the Cuban god of wind, Huracan, and an actual hurricane or tropical
cyclone symbol that is used today. Hurricanes have also made a great
impact on wars. Some of the greatest armies throughout history including
those led by Mongolian warlord, Kublai Khan, were thwarted by the exploits
of typhoons of the day. Hurricanes even played a role in helping the
United States gain its independence during the Revolutionary War. Emanuel
supplements his book with numerous sources of further reading as well
as great appendices for notable tropical cyclones, hurricane records,
and even for his hurricane modeling software.
I downloaded
a copy of this hurricane modeling software, and installed it on my Virtual
PC running Windows XP on my Apple
PowerBook. I played around with the different aspects of the application,
and although I still need to learn more about it, I certainly liked
the added bonus to a great book. I know that I have a tendency to say
every book I've read is a great read, but this book is superb. In the
past,, I've studied Emanuel's work
and research, and I used some of it to write my own paper on Category
Five Hurricanes, which I also wrote an article
about on this site several years ago. However, I really enjoyed this
book, and I was very glad that I bought it. As a result, I strongly
urge all of you, who have not purchased, or read this book, to buy it.
While I know that all of you are not math and science oriented like
I am, I think you will still find certain aspects of this book quite
enjoyable.
