According to related new research, tropical cyclones (热带气旋), from hurricanes to typhoons, are moving more slowly across the globe than they did decades ago, meaning that they get more destructive power and last longer.
It may seem like a good thing that cyclones pace at a slower speed, but in fact it’s not the case. Although the cyclones are moving slower across the ground, they still get high wind speeds inside, which makes hard rains stay longer over communities.
“Nothing good comes out of a slowing storm,” says James Kossin, a climate scientist, “It can increase the amount of time that buildings are suffering strong wind. And it increases rainfall.”
According to Kossin’s findings, changing storm patterns (模式) is causing greater destruction in another way. He noted that the speed of global tropical cyclones slowed by an average of 10 percent from 1949 to 2016. The pace of the storms slowed even more as they made landfall in some regions (地区). In the western North Pacific, it slowed down by nearly a third. That means there will be more time for a storm that may already contain large quantities of water to give off more of it in each place.
Basing his research on the details of nearly 70 years’ worth of storms, Kossin did not try to determine the cause of the slowdown. Even so, the change is the expected result of climate change, just as he and other cyclone experts said.
Kossin’s work was considered to be “important and new” and “pretty reasonable” by Christina Patricola, who has been studying this issue.
It is Kossin’s hope that a model (模型) showing which communities are likely to be at the highest danger could be developed by scientists. Given that in some areas, the storms are moving poleward (极地) and gaining in strength as well, places not normally passed by could be affected by unusually heavy rainfall as a result. “These are not good things to be put together,” he says.
