Kaus Raghukumar and Chris Flanary to Attend NCEP/NOAA Waves Summer School 2018

Western North Atlantic domain in Integral’s operational real-time wave modeling system.

Integral scientists Kaus Raghukumar, Ph.D., and Chris Flanary, Ph.D., will attend the National Center for Environmental Prediction/National Oceanic and Atmospheric Administration (NCEP/NOAA) Waves Summer School 2018, to further develop their expertise in wave modeling and the use of the WAVEWATCH III® (WW3) model. The expanded expertise will benefit continued development of Integral’s operational real-time wave modeling system, current proposed efforts, and future opportunities. The class will be held at the University of Maryland College Park campus on July 9–13, 2018.

Topics covered will include wave dynamics and modeling, features/capabilities of the WW3 model, structured and unstructured grid development, model calibration and validation, data assimilation techniques, and oceanic and nearshore applications. Consisting of morning lectures and afternoon tutorials, the workshop is directed at graduate-level students and professionals.

Integral’s operational real-time wave model and custom front end display offer clients an interactive display of model domains and near real-time access to wave forecasts. The Integral model forecasts run every 6 hours, the same frequency at which Global Forecast System wind forecasts are available from NCEP/NOAA. Each wave simulation forecasts out 8 days. Nested model domains of varying spatial extents (e.g., see above figure, Western North Atlantic, Northeast Pacific, Monterey Bay, Gulf of Mexico) are supplied boundary conditions from a global scale parent wave model. Upon request, new model domains around the world can be easily enabled and added to the real-time operational model.

While WW3 is a publicly available model and widely used in the scientific community, the adaptive tools to run WW3 in real time and the rapid creation of new model domains used in Integral’s wave modeling system were developed in house. These Integral-developed tools provide an efficient method for running and displaying predictions from multiple nested model domains and the tools are easily adaptable to other numerical models to provide automated quality control and real-time operation.
