The model’s 3 km resolution is significant because it means scientists do not need to use parameterization schemes—a method used to predict the collective effects of many clouds that might exist within a grid box—in the model.
Parameterizations often result in models that underestimate a storm’s intensity, says Brian Etherton, a senior atmospheric scientist at RENCI. Storm intensity also affects the storm track, so RENCI’s model predicts a somewhat different track than the models run by the National Center for Environmental Prediction (NCEP), the National Weather Service division that provides most of the commonly used forecasting products.
“Our model shows Earl coming closer to the coast than the NCEP forecasts,” says Etherton. “The National Weather Service offices in Raleigh, Wilmington and Morehead City are all looking at our output. It is a research tool that we can compare to other models. When the storm is over we can evaluate our model and its value in predicting the track and intensity of Earl.”
The high reolution WRF model was developed in collaboration with Gary Lackmann, an atmospheric scientist at North Carolina State University.
In addition to the WRF model, RENCI scientists are modeling coastal storm surge and waves associated with Hurricane Earl. Those models show that waves up to 4 meters high (more than 12 feet) might occur off the North Carolina coast by Friday. The models will also show storm surge, or the height of water pushed inland by the storm, as the storm moves closer to North Carolina.
All the models are run twice a day using RENCI’s Dell/Intel supercomputer Blue Ridge, which is capable of 8 trillion calculations per second.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
