John C. "Chris" Broyles is an American meteorologist who is a weather forecaster and tornado forecasting expert with the Storm Prediction Center.[1][2][3]

Education

[edit]

Broyles attended St. Edwards University in Texas, before transferring to the University of Northern Colorado, where he graduated with bachelor's degrees in meteorology and journalism.[1]

Career

[edit]

In 1994, Broyles was hired as an intern at the National Weather Service (NWS) office in Jackson, Kentucky.[1] Following his internship, Broyles was hired as a forecaster at the NWS office in Aberdeen, South Dakota.[1] In 2003, Broyles was hired at the Storm Prediction Center (SPC) at the National Weather Center in Norman, Oklahoma as a forecaster.[1] Throughout his career forecasting at the SPC, Broyles issued 13 High Risk Outlooks, with 10 verifications.[1] On April 7, 2006, Broyles issued the first-ever Day-2 High Risk Outlook, in preparation for the tornado outbreak of April 6–8, 2006.[1] This High Risk also included a 60% chance of tornadoes, including at least some becoming significant.[1] Following verification of this High Risk, the United States Department of Commerce awarded Broyles with a Silver Medal.[1] On April 14, 2012, Broyles issued the second-ever Day-2 High Risk Outlook, while forecasting for the tornado outbreak of April 13–16, 2012.[1]

Publications

[edit]

Throughout his career, Broyles has authored and co-authored several academic papers and case studies. Besides academic publications, Broyles led a team of twenty others to create the National Oceanic and Atmospheric Administration's Violent Tornado webpage, which documented more than 200 tornado outbreaks throughout the United States' history.[1][4]

  • The role of synoptic patterns and temperature and moisture distribution in determining the locations of strong and violent tornado episodes in the north central United States: A preliminary examination. in 2000.[6]
  • The Effect of a Low-Level Boundary on the Development of the Panhandle, TX Tornadic Storm on 29 May 2001 in 2002.[7]
  • Synoptic and mesoscale characteristics associated with violent tornadoes across separate geographic regions of the United States: Part 1 - low-level characteristics & Part 2 - upper-level characteristics in 2002.[8][9][10]
  • Radar characteristics of violent tornadic storms using the NSSL algorithms across separate geographic regions of the United States in 2002.[11][12]
  • An Iterative Storm Segmentation and Classification Algorithm for Convection-Allowing Models and Gridded Radar Analyses in 2022.[13]
