Climate Change and Tropical Cyclones (Hurricanes)
Climate change leads to changes in the activity of storms and hurricanes.
The Report "Weather and Climate Extremes in a Changing Climate" published 2008 by the U.S. Climate Change Program (CCSP) mentions the following impacts of climate change on tropical cyclone activity:
"Atlantic tropical cyclone (hurricane) activity, as measured by both frequency and the Power Dissipation Index (which combines storm intensity, duration, and frequency) has increased. The increases are substantial since about 1970, and are likely substantial since the 1950s and 60s, in association with warming Atlantic sea surface temperatures. There is less confidence in data prior to about 1950." (CCSP 2008)
"It is very likely that the human-induced increase in greenhouse gases has contributed to the increase in sea surface temperatures in the hurricane formation regions. Over the past 50 years there has been a strong statistical connection between tropical Atlantic sea surface temperatures and Atlantic hurricane activity as measured by the Power Dissipation Index (which combines storm intensity, duration, and frequency). This evidence suggests a human contribution to recent hurricane activity." (CCSP 2008)
"It is likely that hurricane/typhoon wind speeds and core rainfall rates will increase in response to human-caused warming. Analyses of model simulations suggest that for each 1°C increase in tropical sea surface temperatures, hurricane surface wind speeds will increase by 1 to 8% and core rainfall rates by 6 to 18%." (CCSP 2008)
"The spatial distribution of hurricanes/typhoons will likely change." (CCSP 2008)
