Ocean Roughness, Breaking Waves Affect Hurricane Predictions

28.07.2004


Recent efforts to improve hurricane tracking and intensity predictions have focused on the effect the ocean has on the movement of hurricanes. University of Rhode Island oceanographers have demonstrated how the roughness of the ocean surface affects the speed and intensity of these powerful storms.

"Hurricanes are very complex weather systems that are affected by any number of parameters in the atmosphere, the ocean, and on land," said URI Oceanography Professor Isaac Ginis. "The more parameters we can incorporate into the computer models, the more accurate the prediction system is."

Ginis and URI colleagues Il Ju Moon and Tetsu Hara have just received a three-year $412,000 grant from the National Science Foundation to incorporate into current computer models the impact of surface waves on the interaction between the ocean and the atmosphere, and, consequently, how this interaction affects hurricane intensity, track, wind waves, and ocean prediction.



The grant will allow the researchers to incorporate the breaking wave effect into their Coupled Wind-Wave model. They anticipate that this effect will allow the model to more accurately estimate the amount of drag exerted on the storm. After testing, the new model will be incorporated into the current hurricane prediction model developed by the University of Rhode Island and the Geophysical Fluid Dynamics Laboratory at Princeton University presently being used by the National Hurricane Service.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
