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.

In many regions of the world, protecting water for natural areas is an urgent matter. There are many ideas and potential lessons to be learned from our international neighbors to help Arizona reframe the link between healthy watersheds and healthy, thriving businesses and communities.
