英文摘要: The state of California has experienced the worst drought in its historical record during 2012-2015. Adverse effects of this multiyear event have been far from uniformly distributed across the region, ranging from remarkably mild in most of California's densely populated coastal cities to very severe in more rural, agricultural, and wildfire-prone regions. This duality of impacts has created a tale of two very different California droughts - highlighting enhanced susceptibility to climate stresses at the environmental and socioeconomic margins of California. From a geophysical perspective, the persistence of related atmospheric anomalies has raised a number of questions regarding the drought's origins - including the role of anthropogenic climate change. Recent investigations underscore the importance of understanding the underlying physical causes of extremes in the climate system, and the present California drought represents an excellent case study for such endeavors. Meanwhile, a powerful El Niño event in the Pacific Ocean offers the simultaneous prospect of partial drought relief but also an increased risk of flooding during the 2015-2016 winter - a situation illustrative of the complex hydroclimatic risks California and other regions are likely to face in a warming world. Key Points California has experienced the worst drought in its historical record during 2012-2015 Effects of this event have been relatively mild in some sectors but very severe others El Niño presents the simultaneous prospect of drought relief but also an increased risk of flooding. © 2015.
