Paper: Winter Precipitation Changes in California Under Global Warming: Contributions of CO2, Uniform SST Warming, and SST Change Patterns
Authors: L. Dong and L. R. Leung

As with any job tasked with predicting the future, climate scientists have a tough but important responsibility: understand how the climate will be different at the end of the century. Predicting future climate is especially critical in areas with large, vulnerable populations and that grow a large part of the food supply. California, for example, has a population of over 39 million and is a source of two-thirds of the fruits and one-third of the vegetables grown in the US. Changes to its climate will impact not only its own residents but also the population and economy of the whole country.

Paper: Dusty Atmospheric Rivers: Characteristics and Origins

Authors: Kara K. Voss, Amato T. Evan, Kimbery A. Prather, and F. Martin Ralph

Atmospheric rivers, narrow plumes of highly concentrated water vapor in the atmosphere, can cause heavy rain over the coastal western United States and southwest Canada. In fact, up to half of California’s annual rainfall comes from atmospheric rivers, and while this rain helps replenish California’s water sources, it can also cause flooding and mudslides. A new study sheds light on how dust kicked up from deserts halfway around the world in Africa and Asia may influence these atmospheric rivers and control California’s rain patterns.
