The Authors

Zac Flamig Zac Flamig is a Ph.D candidate in the School of Meteorology at the University of Oklahoma. Zac’s research interests include hydrologic modeling at small scales and large domains, crowd sourced data collection, and radar meteorology. Zac holds a BS and MS from the University of Oklahoma.

Humberto Vergara Humberto Vergara hails from Colombia is currently a Ph.D candidate in the School of Civil Engineering and Environmental Science at the University of Oklahoma. Humberto’s main research interests are in hydrologic modeling, simulated streamflow error modeling, ensemble forecasting and data assimilation. He holds a BS from El Bosque University and a MS from the University of Oklahoma.

Race Clark Race Clark is currently a Ph.D candidate in the School of Meteorology at the University of Oklahoma. Race’s focus is on pre-flash flood environments and numerical weather prediction forecasts of those environments. He holds a BS from Oklahoma State University in chemical engineering and a MS in meteorology from the University of Oklahoma.


JJ Gourley JJ Gourley is a research hydrologist at NOAA’s National Severe Storms Laboratory and affiliate associate professor with the School of Meteorology at the University of Oklahoma. His research interests include hydrologic prediction across scales ranging from water resources management to early warning of extreme events. Dr. Gourley was the principal inventor of a multisensor rainfall algorithm that was expanded to encompass all radars in North America and deployed to several foreign countries for operational use. He also assembled a comprehensive database that is being used to develop FLASH—a real-time flash flood forecasting system. He holds a BS, MS, and Ph.D from the University of Oklahoma.

Yang Hong Yang Hong is a professor in the School of Civil Engineering and Environmental Sciences at the University of Oklahoma. Dr. Hong directs the Hydrometeorology and Remote Sensing (HyDROS) Lab at the National Weather Center. He is also co-director of the WaTER Center, faculty member with the Advanced Radar Research Center (ARRC), an adjunct faculty member with the School of Meteorology, and affiliated member of the Center for Analysis and Prediction of Storms. Dr. Hong’s research interests include remote sensing of precipitation, evapotranspiration, soil moisture, and streamflow. He is also interested in monitoring, prediction and prevention of disasters. He holds a BS and MS from Beijing University, China and Ph.D from the University of Arizona.
