A Geophysical Research Letters report concludes that maximum potential rainfall will likely increase as climate change increases average temperatures. Kenneth J. Kunkel, et al., “Probable Maximum Precipitation and Climate Change,” American Geophysical Union, April 12, 2013. The study used modeling to assess the effects that predicted increases in average and maximum water vapor concentrations in the atmosphere will have on the highest precipitation amount meteorologically possible in a given area. The authors conclude that the “most scientifically sound projection” is that these probable maximum precipitation values will increase in the future.
