Cyclone Frequency and Intensity
The frequency of tropical cyclones has remained constant over the past four decades, but their intensity has increased, with more cyclones reaching higher wind speeds. The number of the most devastating category five cyclones has risen by 40 percent in the last decade, aligning with climate change projections. Humanitarian crises resulting from cyclones are largely due to poverty, vulnerability, and a lack of protection for affected populations. Cyclone Frequency and Intensity An analysis of international databases confirms that while the annual number of tropical cyclones has remained steady over the past four decades, their intensity has increased. Since 1980, there has been an average of 47 cyclones each year, according to data from agencies recognized by the World Meteorological Organization and coordinated by the US Oceanic and Atmospheric Administration. Although the frequency has not changed, the average maximum wind speed of these cyclones has increased by five percent, from 182 t…
