As a Category 5 hurricane, Dorian equaled or broke records for its intensity and snail-like pace. Dorian’s intensification was unprecedented, with its winds increasing from 150 mph to 180+ mph in only nine (9) hours. When Dorian made landfall, its sustained winds of 185 mph tied the record for the strongest winds ever observed in the Atlantic. Perhaps more shocking, though, was how slowly it crawled over the Bahamas, allowing the wind to build up the huge wall of water for the storm surge, inundating the area repeatedly with drenching rains, and pulverizing most everything in its path with EF-4 (185) mph tornadic-like swirling winds for 48 hours.
While Dorian is a record-setting hurricane, it also fits a pattern. Dorian made 2019 the fourth straight year in which a Category 5 hurricane formed in the Atlantic Ocean, the longest streak on record. And climate scientists warn that Dorian may be a harbinger of what hurricanes will increasingly look like as the climate continues to warm.
“The link between rapid intensification and climate change is robust,” says Jennifer Francis, an atmospheric scientist at Woods Hole Research Center.
Because a hurricane’s primary source of fuel is heat in the ocean, as the oceans continue to warm, there is plenty of energy available for storms like Dorian to develop and grow rapidly. Additionally, warm air holds more moisture. Increasing water vapor in the atmosphere is leading to wetter hurricanes, more extreme rainfall events, as well as providing extra fuel for developing storms.
So what does this mean? Climate models predict that Category 4 and 5 catastrophic hurricanes in the Atlantic could become almost twice as common in the Atlantic over the next century as a result of climate change.
Hurricane Dorian was far more devastating because of the way it stalled over the Bahamas. Unfortunately, stalling events are becoming more common with hurricanes and tropical cyclones. In 2017, Hurricane Harvey sat over southeast Texas, dumping more than five (5) feet of rain, and Hurricane Florence in 2018 deluged the Carolinas.
“As the Earth’s atmosphere warms, the atmospheric circulation changes. These changes vary by region and time of year, but there is evidence that anthropogenic warming causes a general weakening of summertime tropical circulation. Because tropical cyclones are carried along within their ambient environmental wind, there is a plausible a priori expectation that the translation speed of tropical cyclones has slowed with warming.” (James P. Kossin, 2018, A Global Slowdown of Tropical-Cyclone Translation Speed, Nature 558, 104-107)
In other words, hurricanes have no engines to move on their own; they are steered by large-scale atmospheric winds and if these guiding winds shift or collapse, the hurricane doesn’t move, making these types of hurricanes more difficult to track.
JOIN Barb and John as they discuss Hurricane Dorian and What Storms May Come.
Joining the show during the second hour is chiropractic physician and author, Ya-Ling J. Liou, who will be discussing her book, Every Body’s Guide to Everyday Pain.
Persistent aches and pains plague nearly one-fifth of all adults in the U.S., according to a National Health Interview Survey. But victims can learn to identify the culprits of their pain from reading their body’s clues.
Burning pains or stabbing pinches are the body’s way of telling you that you need to pay attention. Once serious underlying causes are ruled out through blood tests, MRIs or X-rays, you can do the detective work to trace the pain back to its trigger point–whether the cause is mechanical, chemical, emotional, or some combination of the three.
When you try to ignore or power through your pain, you teach your brain to get good at being in pain, warns Ya-Ling Liou, a pain management expert. This is how chronic pain sets in. Targeting the situations that cause pain allows you to take back control.
Ya-Ling will spell out the functions of the systems involved in pain so that you can become your own expert on healing what ails you. Her advice, based on sound medical science, offers hope to those who have been living with chronic pain and helps them become their own experts in pinpointing and alleviating their nagging points.
Ya-Ling Liou, D.C., is a chiropractic physician who earned her doctorate from New York Chiropractic College. After more than 20 years of clinical experience, she continues to expand and share her intuitive body care techniques. Her book, Every Body’s Guide to Everyday Pain, takes into account the whole person, and aims not only to address the mechanical balance of the body, but also the chemical and emotional aspects that so often influence this balance. Dr. Liou lives, works, and writes in Seattle.
