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: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
