Ever wondered what springs in the wilderness look like—or how many are out there?
WRRC Brown Bag - Advances in Forecasting Summer Monsoon Precipitation, Simulation of Convective Storm Processes
Chris Castro, Associate Professor, Hydrology / Atmospheric Sciences, University of Arizona
In his presentation, Dr. Chris Castro will describe research on the changing occurrence and intensity of monsoon rains. This research focuses on the simulation of severe weather events caused by mesoscale convective systems (MCSs), which account for much of monsoon rainfall in the central and southwestern portions of Arizona, downwind of the Mogollon Rim. Over the past 60 years, there have tended to be a fewer strong, organized MCS-type thunderstorms during the monsoon; however, when they do occur, their associated precipitation tends to be more intense. Central/southwestern Arizona appears to be a local hot spot for increasingly intense precipitation and downdraft winds. Dr. Castro is a UA faculty member in the Department of Hydrology and Atmospheric Sciences, where his current research focusses on the understanding and prediction of climate through atmospheric modeling and analysis of observations.

Water Roots: Springs in our wildest places
WRRC Brown Bag - Navigating Water Policy in Uncertain Times: New vs. Old Paradigms
What does water security mean in the 21st century and how do we reconfigure water policy for a more sustainable future? Although drought and water scarcity have driven conflict throughout history, there are increasing efforts across the U.S. to bring a more collaborative and systems-based approach to water governance. This talk examines the current water policy landscape and the ways in which a clash of paradigms is playing out between the legacy systems of the past and the new paradigm solutions of the future.
New Techniques for Mapping planted versus fallowed croplands using MODIS data
An important metric to monitor for optimizing water use in agricultural areas is the amount of cropland left fallowed, or unplanted. Fallowed croplands are difficult to model because they have many expressions; for example, they can be managed and remain free of vegetation or be abandoned and become weedy if the climate for that season permits.
