Precipitation varied across the Southwest in March, but temperatures remained warm throughout the region. Drought-designated areas were expanded in the April 17 U.S. Drought Monitor, with Arizona and New Mexico documenting increases in the extent and intensity of drought. The three-month outlook for April through June calls for equal chances of above- or below-average precipitation in Arizona and New Mexico and increased chances of above-average temperatures for the entire southwestern United States.
The UA is an international leader in climate science, impacts and policy. We use paleoenvironmental techniques to reconstruct past climates and computer models to understand future conditions. We look at how patterns of drought and heatwaves change and cause water shortages, increase wildfire risks, reduce crop production and food security, threaten defense installations, and affect human health and ecosystems. We work with partners to deliver usable climate science and to create effective responses that help people focus on adaptation, resilience, and risk reduction in the face of climate change.
