UA Researcher Awarded Grant for Severe Weather Public Communication Study

Dr. Cory Armstrong

The University Corporation for Atmospheric Research, or UCAR, has awarded a $15,000 grant to The University of Alabama’s Dr. Cory Armstrong to examine the effectiveness of tornadic-related weather information on the general public.

Her project, “Does that work for you? Comprehension and Interpretation of NWS Weather Graphics by Urban and Rural Mid-South Residents,” was funded by UCAR’s Cooperative Program for Operational Meteorology, Education and Training, or COMET. Armstrong and her team will survey residents in Tennessee, Mississippi and Arkansas to determine how they interpret severe weather information and plan accordingly.

“For example, when you hear the words ‘watch’ versus ‘warning,’ we want to know what your response is to that,” said Armstrong, a professor and the department chair of Journalism and Creative Media in UA’s College of Communications and Information Sciences. “What do you do when you hear certain pieces of language or see that a tornado is coming into your general area?”

Armstrong is partnering with the National Weather Service Office in Memphis for the survey. One focus will be on if people in urban areas respond differently than those in rural communities. Surveys will be distributed to all areas serviced by Memphis, but her team is particularly interested in northwestern Mississippi as it has been an area with significant tornadic activity over the past five years.

The survey will take approximately 30 minutes to complete, and various versions will be sent to different populations. Some surveys will focus on visual communications while others will concentrate on written language. Once those are complete, they will be evaluated and the data presented to the NWS and their partners, such as emergency managers and disaster relief organizations.

“They can think about how they might fine tune their messages to the public and think about specific audiences that might have different responses,” she said. “For rural areas, they might send people to storm shelters versus if you’re in an urban area, you might want to consider going to your basements and places like that.”

How well people listen to professional meteorologists and the timing of severe weather warnings will also be factored into the response data.

“We’ve been talking about finding a sweet spot for how much warning people really want before a tornado, and we’ve found that to be about 15 minutes in prior studies,” said Armstrong. “If it’s more than that, they might delay their preparation.”

The surveys are expected to be sent out to the public around May, and the goal is to complete the grant within the following months. The results and analysis should be finished and distributed to the agencies by the end of the year.

Armstrong’s research team includes Dr. Matthew VanDyke, an assistant professor in advertising and public relations, and Dr. Karen Bareford, from the Alabama Water Institute and NOAA’s National Water Extension liaison.

The COMET Program is part of UCAR’s Community Programs and is sponsored by NOAA’s National Weather Service.
