Arizona has experienced dramatic hydroclimatic variability over the past several years with back-to-back record warm and dry summers and an intervening winter season with near average precipitation in 2020. The winter season of 2021 was also drier and warmer than average helping to intensify short-term drought conditions across the state. At the same time, longer-term drought conditions dating back to the mid-90’s continue to impact water resources across the region. What is the difference between short and long-term drought and its impact on different resources? Is this type of shorter-term climate variability normal for Arizona or a harbinger of things to come? Will the current long-term drought end? This presentation with Dr. Crimmins, faculty of the Department of Soil, Water, and Environmental Science at the University of Arizona and Climate Science Extension Specialist for Arizona Cooperative Extension, will explore the unique aspects of Arizona’s hydroclimate that control precipitation variability at both short and long timescales as well as how increasing temperatures relate to drought conditions. We will also explore climate model projections for Arizona and what they mean in terms of potential changes in temperatures and precipitation patterns in the coming decades.
Dr. Crimmins’s extension and research work supports resource management across multiple sectors including rangelands, forests/wildfire, and water resources as well as informing policy and decision makers. This work aims to support managers by increasing climate science literacy as well as developing strategies to adapt to a changing climate. He also serves as a drought monitoring expert on the Arizona Governor’s Drought Task Force and has worked with counties across Arizona to implement drought preparedness and impact monitoring plans.
