The study suggests an average cyclone by then will last around 5 hours longer and will travel 92 kilómetros (57 millas) farther inland, nearly doubling their destructive power.
Tropical cyclones are among the most dangerous natural disasters, with flooding rainfall, damaging winds and storm surge. Sobre el pasado 50 años, these cyclones have led to nearly 780,000 deaths and around $ 1.4 billion worth of economic losses globally.
En junio, Typhoon In-fa and Typhoon Cempaka brought extreme rain of more than 150mm per hour to China’s Henan province
, breaking a record in the city of Zhengzhou
. Más que 300 la gente fue asesinada in the floods that ravaged central China
, los funcionarios dijeron.
And in September 2021, the remnants of Hurricane Ida caused torrential rain and flash flooding in New York, dejando al menos 50 gente muerta.
“Both disasters caused huge economic and human losses,” the study’s lead author, Dr Chi-Yung Tam of the Chinese University of Hong Kong said.
Tam and his colleagues are calling for more action to reduce planet-warming greenhouse gas emissions and increase disaster preparedness in Asia.
Several studies suggest that warmer ocean temperatures are intensifying tropical cyclones.
One of those studies
, from researchers at the University of Wisconsin in Madison and the National Oceanic and Atmospheric Administration
(NOAA), looked at nearly
40 years of satellite data of global storms
. El estudio, published last year
, found that global warming has increased sea surface temperature in regions where tropical cyclones form
. The combination of these warm temperatures
, along with changes in atmospheric conditions
, have allowed storms to more easily reach higher intensities
If a cyclone intensifies in strength at landfall, it will travel further inland, amplifying its destructive power.
While human-caused global warming is likely fueling the increase in the severity of the storms, natural weather cycles and events can also strengthen — or weaken — the intensity and frequency of cyclones.
Tam said numerical models predict the climate crisis “will likely continue the increasing trend in landfalling typhoons and their impacts on inland regions.”
“More Asian inland regions may be exposed to more severe storm-related disasters in the future as a result of the climate crisis,” él dijo.
