Imagine standing at the center of a Roman coliseum that is 20 miles across, with walls that soar 10 miles into the sky, towering walls with cascades of ice crystals falling along its brilliantly white surface. That's what it's like to stand in the eye of a hurricane. In Divine Wind , Kerry Emanuel, one of the world's leading authorities on hurricanes, gives us an engaging account of these awe-inspiring meteorological events, revealing how hurricanes and typhoons have literally altered human history, thwarting military incursions and changing the course of explorations. Offering an account of the physics of the tropical atmosphere, the author explains how such benign climates give rise to the most powerful storms in the world and tells what modern science has learned about them. Interwoven with this scientific account are descriptions of some of the most important hurricanes in history and relevant works of art and literature. For instance, he describes the 17th-century hurricane that likely inspired Shakespeare's The Tempest and that led to the British colonization of Bermuda. We also read about the Galveston Hurricane of 1900, by far the worst natural calamity in U.S. history, with a death toll between 8,000 and 12,000 that exceeded the San Francisco earthquake, the Johnstown Flood, and the Okeechobee Hurricane co Boasting more than one hundred color illustrations, frommbined. Boasting more than one hundred color illustrations, from ultra-modern Doppler imagery to classic paintings by Winslow Homer, Divine Wind captures the profound effects that hurricanes have had on humanity. Its fascinating blend of history, science, and art will appeal to weather junkies, science buffs, and everyone who read Isaac's Storm .
Kerry Emanuel is an American atmospheric scientist and professor of meteorology at MIT, known for his work on hurricane dynamics and climate change. He gained attention for proposing the concept of the "hypercane," a theoretical super-hurricane driven by extreme ocean warming. His research suggests global warming may increase storm intensity but reduce their frequency. Emanuel co-founded the MIT Lorenz Center to advance climate science. A vocal advocate for climate action, he has also supported the role of nuclear energy in reducing carbon emissions. In 2006, Time named him one of the world’s 100 most influential people. He is a member of the U.S. National Academy of Sciences, the American Philosophical Society, and a Foreign Member of the Royal Society.
I once bought 12 copies of this book using the prize money for the Brian Hey Prize (https://www.actuaries.org.uk/about-us...) for the best paper presented at the 2006 GIRO conference in Vienna, a paper by a Working Party I chaired on Catastrophe modelling
So it has been very enjoyable to revisit the book fifteen years later as part of my continuous professional development – given my recent increase in responsibilities to include international catastrophe management for a global insurer.
It really is an outstandingly designed book on two levels – one which set a standard for popular science books that few I have read since have come close to matching.
Firstly in presentation – this is a coffee table style book – larger than A4 with glossy pages and copious full colour illustrations.
Secondly in its mixture of hard science, history, literature and art.
The chapters of the book alternate between two series.
The first covers the science of hurricanes – starting with an overall introduction to them and then starting from metrological basics to develop this further: beginning with the impact of the greenhouse effect and atmospheric heat transfer (particularly cumulus convection), then:
Tropical rain shower formation; trade winds (and particularly the impact of the Hedley circulation), Carnot’s heat engine and how an idealised hurricanes comes close to this idea (including the crucial idea that the evaporation of warm sea water is what fuels hurricanes);
Intensity – and particularly the complex role of wind shear and ocean interaction in limiting intensity from theoretical maximums – and how this makes forecasting challenging;
Hurricane development (as Emanuel says, once the basic science of is understood “the problem for research scientists is not why hurricanes develop, but why they hardly [ever] happen”) – this chapter looks again at wind shear, at sea temperature but also at the need for cyclonic vorticity (which stops hurricanes at the equator despite the warmer sea temperatures) and then goes on to discuss Gray’s genesis index which allows for these factors – the chapter then goes on to discuss the starters for hurricanes and particularly the role of African Easterly Waves flowing from the Sahara; the death (often over land) or transition (often into extra-tropical cyclones) of hurricanes;
The complex factors of atmospheric flow on determining the paths of hurricanes – this chapter is understandably hard to follow which is perhaps no surprise given the almost impossible task of accurately forecasting storm tracks;
Storm surge (often responsible for the most terrible loss of life – and the key reason why cities should not be built on hurricane prone coastlines – something which Emanuel mentions on a number of times the Mayans learnt but we have not); waves;
Rain – the chapter points out the often disregarded risk of catastrophic rainfall – for example over mountainous terrain, after interaction with another weather systems or after storms regain power after moving over inland water; Hurricane forecasting – the chapter describes the Lorenzo Chaos Theory limitations on forecasting, the use of ensemble models and interestingly starts with three “nightmare” scenarios for forecasters. The first two discuss storms which, depending on track, either threaten to wipe out the Florida Keys or to give a huge storm surge to Manhattan or to simply drift out to sea – and the dilemma of whether to evacuate or not. The third though, rather fascinatingly for a book which was completed in 2004 (one year before Katrina), discusses the risk of a Hurricane hitting New Orleans and causing catastrophic flooding;
Climate change – this is a brief chapter which looks both at research into historical hurricane patterns and the potential impact of global warming in future. As an aside – a year or so after the book was written the author published a paper on the likely impact already of global warming (largely via sea surface temperatures) on storm size (or frequency of large storms) – and when this was followed only a little time later by Hurricane Katrina, the author was suddenly propelled to fame (e.g. Time Magazine had him as one of the Top 100 most influential people of 2006) (http://content.time.com/time/specials...)
The second series of chapters covers a chronological history of hurricanes (mainly with chapters focusing on an individual historical hurricanes, with something of a 20th Century and American bias) – examples include 1900 Galveston, 1926 Miami, 1938 Great New England, Hurricane Camille, Cyclone Tracy and 1992’s Hurricane Andrew.
These chapters really bring the hurricanes to life – drawing on contemporary accounts (including eyewitness reports and in some cases novels inspired by the events) combined with maps, storms tracks, before/after photographs but also using modern techniques (for example in many cases retrospective simulations of the hurricane).
There are also some one off chapters – on nomenclature, on hurricane hunters and a beautiful if terrifying photo essay from inside hurricanes.
Between each chapter – and really adding to both aspects of what makes the design outstanding – are, each time, a hurricane related piece of artwork and
If I had a criticism of the science chapters is it that they, at least for me, seemed to quickly become hard to follow. The complexity of and uncertainty in the physics I think meant that these chapters needed more in the way of word pictures and illustrative analogies rather than the often equally technical graphs and diagrams provided. However in many cases it was the history chapters that both went on to better illustrate the principles and ideas – and translate the theory into genuine outcomes and impacts – which anyway, for my purposes, is of greater interest anyway.
An amazing book about hurricanes that really sets a standard for popular science books: it has art, and poetry, and science, and case studies of hurricanes/typhoons throughout history. Plus it's just really well-written.
I thought this would be more narrative and chronological, but it reads more like a jargon-bursting textbook. A bit dense for us non-science folks, but I loved the attention to detail and the analyses of Cyclone Tracy, Galveston 1900, Labor Day Hurricane, Hurricane Camille, and Hurricane Andrew. I learned a lot about Christopher Columbus' meteorological misgivings in Dominica and the storm of 1780 that rocked the Caribbean. My favorite section was about the Hurricane Hunters reconnaissance missions. It is bone-chilling that so many planes disappeared in the literal eyes of storms and there's still no trace a half a century later.
Divine Wind by Kerry Emanuel is an excellent introductory text for learning and understanding the history and science of tropical cyclones. The author seamlessly blends art, science, and history to take you on an engaging learning journey about this fascinating phenomenon. Although the book is written in a popular science style, it discusses the most important concepts in a very clear and simple way, making the science behind tropical cyclones accessible. This is a great book if you want to start learning about this topic.
Dated Hurricane Book (Pre-Katrina) with Some Good Scientific and Historical Insights (But the Audiobook is a Bust)
I listened to this to "get smart" on hurricanes for my work. I learned a few interesting things, but didn't love it overall.
*Brief Synopsis: In this book, Emanuel undertakes to both detail the modern(ish) history of hurricanes and explain the (still-under-review) meteorological forces that create, direct, and dissipate them. It's a sweeping work that ranges from the downfall of invading Mongol fleets, the weakening of the British Navy during the Revolutionary War, and notable modern natural disasters and financial crises resulting from hurricanes.
*Bits that Resonated: I did pick up a good amount of interesting knowledge and insights from this book, including the following: -Hurricanes feed on warm water, and "by trapping heat energy in the ocean, the greenhouse effect sets the stage for the meteorological explosion that is the hurricane." ... "The ability of ocean water to evaporate into the air is essential for supplying energy to a hurricane. ... This evaporation is a direct consequence of the greenhouse effect." -On hurricanes' mind-boggling size and power: "The amount of power dissipated by a typical mature Atlantic hurricane ... is on the order of 3 trillion watts, which happens to be very nearly equal to the worldwide electrical generating capacity as of January 1996." ... "The average hurricane at sea precipitates about one trillion gallons of rain water per day, about triple the rate of fresh water consumption in the United States in 1995." -"There is no known relationship between the geometric size of a storm and its intensity, as measured by its maximum windspeeds." -On preparations (and our society's general unpreparedness): "The ancient Mayans learned by experience to build their cities inland, away from the reach of hurricanes and their storm surges. Yet despite centuries of hurricane disasters, our society continues to disregard collective experience and built more and more structures in storm-prone coastal regions." ... "Policies in force in the United States create strong incentives to build on flood plains. ... (The) government strongly subsidizes risky behavior." ... "A cyclone-free decade or two is all that it takes for a society to forget its past and let down its guard. As far as hurricanes are concerned, there is no substitute for constant vigilance." ... "The time for taking all measures for a ship's safety is while still able to do so. Nothing is more dangerous than for a seaman to be grudging in taking precautions lest they turn out to have been unnecessary. Safety at sea for a thousand years has depended on exactly the opposite philosophy." -"Inland flooding's danger is still underappreciated. While forecasters emphasize the danger of flooding, they continue to rate storms by their maximum winds. And media attention is focused almost exclusively on wind, waves, and storm surge. Reduction of death and injury from inland flooding will require both better education about its true dangers and improved rainfall forecasts." -On the Forecasters' Difficulties: -"Two of the fears that have compromised the integrity of forecasts issued by government weather services: that a forecast of bad weather will have adverse economic consequences, and that the government service will be embarrassed." ... "The problem with hurricanes is that we can forecast them with some skill, yet they move and evolve fast enough that decisions must be made quickly but with incomplete knowledge. Partial knowledge poses a greater problem than either complete ignorance or full knowledge. If we knew for sure a hurricane was coming, we would get out of the way, however inconvenience. If, on the other hand, hurricanes were completely unpredictable (as they were regarded for millennia), we could take prudent precautions, hope for the best, and get on with our lives. But partial knowledge engenders existential angst. We must carefully consider alternatives and decisions can be tough. ... The decisions forecasters make in these circumstances mean the difference between life and death. Underwarn and thousands of lives are placed at risk. Overwarn and lives are lost in automobile accidents, many millions of dollars are wasted on unnecessary evacuations with attendant loss of business, and the act of crying wolf may lead some to ignore future evacuation orders."
*Pre-Katrina: Dated Enough to Make Me Skeptical: This book was published in 2005, but its most up-to-date references are to Hurricane Andrew in 1992. So the science and history in this book are between 20 and 35 years old! I know science and meteorology move lots faster than that (e.g., Emanuel is awed enough and excited about "the possibilities" of computer-assisted predictions as to make it clear he's writing from another era), to the point that I wonder how up-to-date this book's science is. And it felt weird to read a would-be masterwork on hurricanes, especially American hurricanes, that didn't have a chapter on Katrina.
*Failed Audiobook: This book should never have been turned into an audiobook. The narrator regularly referred to graphs, charts, equations, and images that weren't accessible to listeners at all. I probably wouldn't have read this book in print form, but making only about 80% of this book accessible to listeners wasn't a winning formula.
This is a beautifully illustrated book on the science and history of hurricanes. It discusses such famous hurricanes as the Galveston hurricane of 1900, the 1935 storm, the Okeechobee flood, the hurricanes that destroyed the mongol invasions of Japan, the Pacific typhoon that destroyed the US Navy ships in 1944, etc. It discusses in layman's terms how hurricanes work, as giant Carnot engines, as well as facets of their consequences, storm surge, waves, rainfall, winds. There are satellite pictures of hurricanes, scientific illustrations of various variables, storm tracks. Interspersed in all of this are excerpts from stories or poems about hurricanes and artwork depicting them.
Beautifully illustrated with images of cyclones from many different sources, this book intertwines poetry and science in a readable introduction to a devastating force.
Good book entry level book for anyone interested in Hurricanes, that also doesn't want to get bogged down by math or terms that may be unfamiliar to the majority.
Interesting read on everything 'hurricane'. For the science and math buffs there are plenty of equations and graphs to explain the laws of physics that influence these storms (including a link in the appendix to a site that will let you do your own computer modeling of hurricanes- sweet!) but also great stories of Great Hurricanes and the circumstances leading up to, and devastation caused by, them. Plus there are photos, paintings and poems that all focus on hurricanes.
