New data from international databases analyzed by AFP reveals that while the number of tropical cyclones per year has remained relatively constant over the past four decades, their intensity has significantly increased. The average maximum wind speed of cyclones has risen by 5%, and the number of high-category cyclones has jumped by 40%. This trend aligns with projections from the UN's Intergovernmental Panel on Climate Change (IPCC), which anticipates an increase in the frequency of powerful cyclones due to climate change.
PARIS, France - The number of tropical cyclones each year has not risen over the past four decades but their intensity has, according to international databases analysed by AFP that confirms the projections of climatologists.Since 1980 there have been an annual average of 47 tropical cyclones -- also called hurricanes and typhoons -- according to the database agencies recognised by the World Meteorological Organization and coordinated by the US Oceanic and Atmospheric Administration .
That is a 40 percent increase in the number of the most devastating, category five cyclones on the Saffir-Simpson scale.These figures support the conclusions of the UN's Intergovernmental Panel on Climate Change which show that climate change is expected to increase the number of category four and five cyclones.
