Chinese scientists from Tsinghua University have found a link between the increasingly early occurrence of powerful tropical cyclones and global warming caused by man-made emissions. To work published In the scientific journal Nature.
Cyclones with wind speeds exceeding 110 knots (56.5 m/s) are classified as strong or intense. They are considered one of the most devastating types of natural disasters. Variations in the characteristics of intense tropical cyclones, including their number, intensity, and duration, are well understood, but little is known about changes in their seasonal cycles.
Scientists analyzed satellite data from 1981 to 2017 and found that hurricanes arrived earlier and earlier during that period, with emergence dates changing by about three days every 10 years.
The earlier onset of storms appears to be due to increases in sea surface temperatures and ocean heat content; These increases are primarily due to greenhouse gas emissions.
The results showed that earlier arrivals of tropical storms also led to an increase in the number and duration of heavy rainfall.
