California’s unique geography, with some of the continent’s highest mountains situated close to the broad expanse of the Pacific Ocean helps make California’s precipitation regime the most volatile in the country. This volatility, characterized by large natural swings between drought and extremely rainy years make water resource management in California notoriously difficult. Global climate change is expected to exacerbate the volatility by decreasing the frequency of regional precipitation while increasing its intensity. Join meteorologist Alexander Gershunov to learn how he and other researchers quantify and analyze this volatility to understand the mechanisms behind these changes, and project their anticipated impacts on California.
