A new, Yale-led study suggests the 21st century will see an expansion of hurricanes and typhoons into mid-latitude regions, which includes major cities such as New York, Boston, Beijing, and Tokyo.
Writing in the journal Nature Geoscience, the study’s authors said tropical cyclones — hurricanes and typhoons — could migrate northward and southward in their respective hemispheres, as the planet warms as a result of anthropogenic greenhouse gas emissions. 2020’s subtropical storm Alpha, the first tropical cyclone observed making landfall in Portugal, and this year’s Hurricane Henri, which made landfall in Connecticut, may be harbingers of such storms.
“This represents an important, under-estimated risk of climate change,” said first author Joshua Studholme, a physicist in Yale’s Department of Earth and Planetary Sciences in the Faculty of Arts and Sciences, and a contributing author on the United Nations’ Intergovernmental Panel on Climate Change sixth assessment report published earlier this year.
“This research predicts that the 21st century’s tropical cyclones will likely occur over a wider range of latitudes than has been the case on Earth for the last 3 million years,” Studholme said.
Co-authors of the study are Alexey Fedorov, a professor of oceanic and atmospheric sciences at Yale, Sergey Gulev of the Shirshov Institute of Oceanology, Kerry Emanuel of the Massachusetts Institute of Technology, and Kevin Hodges of the University of Reading.
While an increase in tropical cyclones is commonly cited as a harbinger of climate change, much remains unclear about how sensitive they are to the planet’s average temperature. In the 1980’s, study co-author Emanuel used concepts from classical thermodynamics to predict that global warming would result in more intense storms — a prediction that has been validated in the observational record.
Yet other aspects of the relationship between tropical cyclones and climate still lack physically based theory. For example, there is no agreement among scientists about whether the total number of storms will increase or decrease as the climate warms, or why the planet experiences roughly 90 such events each year.
“There are large uncertainties in how tropical cyclones will change in the future,” said Fedorov. “However, multiple lines of evidence indicate that we could see more tropical cyclones in mid-latitudes, even if the total frequency of tropical cyclones does not increase, which is still actively debated. Compounded by the expected increase in average tropical cyclone intensity, this finding implies higher risks due to tropical cyclones in Earth’s warming climate.”
Typically, tropical cyclones form at low latitudes that have access to warm waters from tropical oceans and away from the shearing impact of the jet streams — the west-to-east bands of wind that circle the planet. Earth’s rotation causes clusters of thunderstorms to aggregate and spin up to form the vortices that become tropical cyclones. Other mechanisms of hurricane formation also exist.
The researchers say that, as the climate warms, temperature differences between the Equator and the poles will decrease. In summer months, this may cause weakening or even a split in the jet stream, opening a window in the mid-latitudes for tropical cyclones to form and intensify.
For the study, Studholme, Fedorov, and their colleagues analyzed numerical simulations of warm climates from Earth’s distant past, recent satellite observations, and a variety of weather and climate projections, as well as the fundamental physics governing atmospheric convection and planetary-scale winds. For example, they noted that simulations of warmer climates during the Eocene (56 to 34 million years ago) and Pliocene (5.3 to 2.6 million years ago) epochs saw tropical cyclones form and intensify at higher latitudes.
“The core problem when making future hurricane predictions is that models used for climate projections do not have sufficient resolution to simulate realistic tropical cyclones,” said Studholme, who is a postdoctoral fellow at Yale. “Instead, several different, indirect approaches are typically used. However, those methods seem to distort the underlying physics of how tropical cyclones form and develop. A number of these methods also provide predictions that contradict each other.”
The new study derives its conclusions by examining connections between hurricane physics on scales too small to be represented in current climate models and the better-simulated dynamics of Earth’s jet streams and north-south air circulation, known as the Hadley cells.

Yes, let’s ignore the “suggestions” and ambiguous possibilities such as “could” and “may.” How about some falsifiable numeric probabilities?
ANTHROPOGENIC!? By which, I assume, you mean Human Caused. That’s a CONCEIT. Unless you are referring to the relatively recent “contributory” effects generated by lame Human attempts at Weather Modification, you are somewhat shy by 23K years. As SOME contend, this “recent change” has been in-play since before the last Ice Age, in a natural Re-Cycling of the Biosphere driven by the Sun. SOME “misguided” souls also contend that the Glaciers will melt off, the Oceans will rise; which in-turn function as a precursor to a gradual descent into the next ICE Age. All very Wholistic, as working Systems tend to be.
Scientific TRUTH! some may chant. It’s in the Numbers! How like Human preoccupations with HANDS, “DIGITAL MODELS” and NUMBERS in general (a SHOW of Hands, as it were: let’s VOTE on on it). Well, let me just say this: That vote don’t count in the larger scheme of “things”. As such, it seems that SOME Humans have missed the Boat AGAIN. On the FLIP-FLOP: Better “get to steppin'” building a new one and a new Worldview Paradigm in advance. The Moon, Mars and (((BEYOND)))… Really(!?) do not offer much hope for the Future.

The largest hurricane ever recorded in the Atlantic Basin, wind gusts topped 100 mph (160 km/h) in some parts of the New York metropolitan area. Sandy was not a hurricane when it hit the NY-CT region. Sandy caused a record 14.41 feet (4.39 m) storm surge at Battery Park, New York City, flooding various parts of Lower Manhattan including various tunnels and subway systems, making them inoperable for weeks. As of late 2019 some are still damaged and are in the process of being repaired, with projects like 14th Street Tunnel shutdown. The immediate aftermath included widespread flooding, massive power outages and a system-wide disruption of mass transit service. Sandy had a significant effect on the digital world: the Federal Communications Commission estimated that the “hurricane…also disrupted cable TV, broadband Internet and landline phone service for 25 percent of customers in the affected areas.” Over nine million customers were without power, including 90 percent of Long Island and most of Manhattan below 49th Street, some for several months.
