Rainstorms in 1960 look different from those in 2017, both in terms of intensity and rainfall.

It's a simple observation, but one with long-term effects on how cities are equipped to handle weather systems. For Marshall Shepherd, director of the University of Georgia's Atmospheric Sciences program, this is one of many pieces of critical information city leaders need as they examine how their communities and living spaces interact with their region's unique climates.

Aware - Impact - Weather - Systems - Headlines

We're all aware of the impact of intense weather systems that make headlines, like 2017's hurricanes Harvey and Irma. But even slight adjustments to weather patterns—like historic changes in precipitation levels and the increasing frequency of heat waves—can drastically change living conditions.

Shepherd's research into urban flooding, for example, shows how outdated assumptions can have detrimental consequences, and his work on a National Science Foundation-funded project to bridge the gap between city planning and weather-climate communities was an important step in the right direction. In conjunction with the Georgia Water Resources Institute, Shepherd and his team are looking at weather pattern trends to determine how vulnerable to flooding people are in certain cities. And as more people flock to urban centers, these research findings are informing the important decisions made by city planners and policymakers.

Work - Impact - Amounts - Rain - Storm

"Our work has a direct impact in understanding how we need to think about planning to cope with increasing amounts of rain," he says. "Our storm management systems are currently designed for last century's rainstorms, under the stationary assumption that rainstorms look the same now as they did a few decades ago. We help city planners and policymakers understand how they can be updated."

Shepherd and his team are also taking a look at how cities can prepare for climate conditions beyond flooding and other extreme weather events. Published in...
