Tropical cyclones in Asia could have double the destructive power by the end of century, 연구 결과

Tropical cyclones in Asia could have double the destructive power by the end of the century, 새로운 연구에 따르면, as scientists say the human-made climate crisis is already making them stronger.

Using data from nearly four decades from 1979 ...에 2016, researchers found that the destructive power of tropical cyclones had dramatically increased, with stronger landfalling cyclones lasting longer and tracking further inland.
연구, by researchers at the Shenzhen Institute of Meteorological Innovation and the Chinese University of Hong Kong and published in Frontiers in Earth Science, said that tropical cyclones now last between two and nine hours longer and traveled an average of 100 km (62 마일) further inland than they did four decades ago.
    The study looked at cyclones over east and southeast Asia and found the Vietnamese capital of Hanoi and the southern China region were hardest hit between 1979 과 2016.
      Researchers also found that by the end of the century, the average landfall wind speed over Asian inland regions could increase by two meters per second, 또는 5 시간 당 마일. Small increases in top wind speeds of a cyclone can bring much higher levels of destruction.
        The study suggests an average cyclone by then will last around 5 hours longer and will travel 92 킬로미터 (57 마일) farther inland, nearly doubling their destructive power.
        Tropical cyclones are among the most dangerous natural disasters, with flooding rainfall, damaging winds and storm surge. 과거에 50 연령, these cyclones have led to nearly 780,000 deaths and around $ 1.4 billion worth of economic losses globally.

          6 월, 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. 이상 300 사람들이 죽었다 in the floods that ravaged central China, 관리들은 말했다.
          And in September 2021, the remnants of Hurricane Ida caused torrential rain and flash flooding in New York, 적어도 떠나 50 죽은 사람들.
          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.

          Intensifying storms

          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. 연구, 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 strengthenor weakenthe intensity and frequency of cyclones.
            Tam said numerical models predict the climate crisiswill 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,” 그는 말했다.
