OOMG Part of NSF AI Institute

US map of NSF AI institutes and partners

The National Science Foundation (NSF) has created five new institutes centered on artificial intelligence (AI) research, and the Ocean Observing and Modeling Group (OOMG) of North Carolina State University is among the principal awardees. The NSF AI Institute for Research on Trustworthy AI in Weather, Climate, and Coastal Oceanography includes of NC State, University of Oklahoma, Colorado State University, SUNY Albany, Texas…

Hurricane Dorian Forecast

The Ocean Observing and Modeling Group at NC State University is closely watching Hurricane Dorian as it moves northward along the U.S. Atlantic coast. Using our Coupled Northwest Atlantic Prediction System (CNAPS), we are providing a 3-day forecast of the hurricane’s path and intensity, updated daily. CNAPS models ocean conditions, atmospheric conditions, and the interaction between them. This interaction is crucial for accurate…

COAWST Training at NCSU

COAWST training group

The biennial COAWST Modeling System Training was held in James B. Hunt Library at NC State University from February 25-28, 2019. Over 100 researchers attended in person or on line to learn more about the Couped Ocean-Atmosphere-Wave-Sediment Transport Model System. Developers and expert users of WRF (Weather Research and Forecasting model, the atmospheric component), SWAN (Simulating WAves Near shore, the wave component), and ROMS…

COAWST Workshop 2019 At NCSU

COAWST workshop

Dr. Roy He, head of OOMG, and Dr. John Warner of the U.S. Geological Survey will co-host a workshop on the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) numerical model in February 2019. The workshop will be four days of intensive instruction in the capabilities, applications, and operations of the COAWST coupled modeling system. Instructors include the developers of the modeling components as well as expert…

Irma Landfall Update, 8-Sept

Our coupled models, initialized at 8pm on September 7th, have completed and are now able to resolve Irma making landfall in Florida sometime between 2am and 5am Sunday morning.  As a result, both the 3 and 7 day runs are capable of resolving the storm and currently point the landfall as occurring between Miami and Homestead (where Andrew made landfall in August 1992)….

Irma 7-Day Forecast Updates (Sept 6 and 7)

Over the last few days, the 7-day forecast experiment upgrade has been working well.  Our output from forecasts initialized on the 6th and 7th are largely in line with the forecast models that the National Hurricane Center (NHC) has been favoring in their forecast tracks.  We have been utilizing additional resources provided by the High Performance Computing (HPC) center at NC State…

For Irma, the First Ever 7-Day CNAPS Forecast

Over the last few weeks, we have been working to expand the current CNAPS forecast from 3 to 7 days.  With the appearance of Hurricanes Harvey and Irma, and the peak of the hurricane season on September 10, we were graciously allocated additional computing power from the High Performance Computing (HPC) Center at North Carolina State University to perform some experimental simulations of…

How Oceanographic Model Coupling Works

Model coupling is the connection of several separate numerical models so that output from each model becomes input for the other models. Models exchange information at specified intervals, so that, for example, predictions about the weather affect and are affected by ocean surface temperature, sea surface roughness, heat flux, etc. This allows a more complete and realistic description of ocean conditions than…

How Oceanographic Models Are Made

Models of ocean conditions are numerical predictions of what the ocean is like at a given time, based on inputs and known physics. The inputs are observations from satellites, moorings, tidal gauges, high-frequency radar stations, and buoys, among other sources. This information is collected daily and fed into the model. The model takes this new data, along with model estimates from the…

OOMG Teaches Weddington Middle Schoolers About Oceanography

Approximately 250 eighth grade students from Weddington Middle School (near Charlotte, NC) began their three-day field trip to NC’s Outer Banks with a marine science presentation by OOMG scientists at NC State University’s James B. Hunt, Jr. Library. On March 29, graduate student Laura McGee, Lab Manager Jennifer Warrillow, and Research Assistant Professor Joe Zambon introduced the students to their research in…
