Megadrought is a term we’ve been hearing a lot of lately, with, as we find out from one of our guests, somewhat varying definitions. The term megadrought is generally used to describe the length of a drought, and not its acute intensity. A related term, aridity, is the degree to which climate lacks effective, life-promoting moisture. Simply put, ar…

Drought impacts more than our physical world - the psychological impacts of drought are also very real. Crop damage or failure, running out of forage for livestock, the loss of culturally important natural resources, and many other drought-related effects can lead to stress, anxiety, and a deep sense of loss. Sometimes it’s hard to know who to talk…

Atmospheric Rivers (ARs) are narrow streams of moisture in the atmosphere that transport water vapor from the tropics to other regions. In the U.S., they mostly impact the West Coast where they account for much of the region’s moisture. ARs can propagate as far inland as Utah, however, and have been identified as the primary source of hydrologic fl…
