Rainfall Modeling

Model simulations spanning 140 years show that warming from carbon dioxide will change the frequency at which regions around the planet receive no rain (brown), moderate rain (tan), and very heavy rain (blue).

Working with NASA scientists, SSAI researchers have performed analyses of   projections of 14 IPCC global climate models that indicate a response to global warming in rainfall characteristics. The analysis provides a new assessment of global warming’s impacts on precipitation patterns around the world. Results suggest that increased CO2 emissions induce a global adjustment in large-scale circulation, manifesting in increasing risks of very heavy rain and prolonged droughts in geographic locations worldwide.

While areas such as the equatorial Pacific Ocean and Asian monsoon regions will see increases in heavy precipitation, arid land areas outside the tropics and many regions with moderate rainfall could become drier. SSAI understands that responses like these carry real impacts, and our concern for the Earth and its inhabitants drives us to uncover critical changes in Earth’s atmospheric system.
