Latest Wind wave Stories

"Anybody who observes waves can see that they are not the same height in winter and summer, but rather that their height varies over time, and we have applied a 'non- seasonal' statistical model in order to measure extreme events such as these", Fernando J. Méndez, an engineer at the Institute of Environmental Hydraulics at the University of Cantabria and co-author of a study published recently in the journal Coastal Engineering, tells SINC.The new model can chart the pattern of...

A U.S. study suggests wind blowing over mountain ranges can generate gravity waves that propagate vertically into Earth's upper mesosphere. Researchers said such waves, known as mountain waves, have previously been observed low in the atmosphere. But Steven Smith, Jeffrey Baumgardner and Michael Mendillo of the Center for Space Physics at Boston University said their research has produced the first unambiguous images of mountain gravity waves in the upper mesosphere -- 50 to 62.5 miles in...

Scientists are postulating a huge wave -- a tsunami -- slammed into the region that is now New York City about 2,300 years ago. The researchers say they've found evidence of a powerful ocean wave dumping sediment and shells across Long Island and New Jersey, and depositing wood debris far up the Hudson River, the BBC reported Monday. Further testing will be done to rule out other possible causes for the upheaval, such as an unusually large storm, the British network said. Steven Goodbred of...

Studying satellite radar data from ESA's Envisat and the Italian Space Agency's COSMO-SkyMed, scientists have begun analyzing the movement of Earth during and after the 6.3 earthquake that shook the medieval town of L'Aquila in central Italy on 6 April 2009.Scientists from Italy's Istituto per il Rilevamento Elettromagnetico dell' Ambiente (IREA-CNR) and the Istituto Nazionale di Geofisica e Vulcanologia (INGV) are studying Synthetic Aperture Radar (SAR) data from these satellites to map...

British mathematicians say they've created a formula that can be used to predict tsunamis and how destructive the tsunamis might become. Scientists at Newcastle University, led by Professor Robin Johnson, studied the 2004 tsunami that devastated coastal communities in Indonesia, Sri Lanka, India and Thailand when an ocean earthquake triggered a long surface wave that resulted in six massive consecutive wave fronts. The third wave, the largest, reached a height of more than 65 feet and, among...

A new mathematical formula that could be used to give advance warning of where a tsunami is likely to hit and how destructive it will be has been worked out by scientists at Newcastle University.The research, led by Newcastle University's Professor Robin Johnson, was prompted by the 2004 Boxing Day tsunami disaster which devastated coastal communities in Indonesia, Sri Lanka, India and Thailand.In this instance, an earthquake in the depths of the ocean triggered a long surface wave which...

MINNEAPOLIS, Feb. 18 /PRNewswire/ -- Newly-elected state congressman Erik Paulsen (R) stopped in Third Wave Systems' headquarters today for a discussion of the company's engineering and technology advancements. During his visit, the congressman visited with TWS administrators and Board members. Paulsen has been vocal with his desire to help small businesses such as Third Wave Systems, which has a staff of 25, as part of a greater effort to keep Minnesota and the United States globally...

Wind and wave data from ESA's Envisat satellite radar are being used to observe meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race.CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), is using the race to demonstrate the ability of Envisat radar imagery to operationally observe oceans at high resolution.Based on the trajectory and speed of the boats, CLS is...

We're starved for clean energy when it is all around us, in the air, water and even the earth. We'd have plenty if we could figure out how to collect it. But technological development must overcome some formidable challenges, especially to mine the powerful energy in water. Water is much denser than air, so harnessing even a small amount of the tidal current flowing in and out of our region's many bays and estuaries, or the deep-ocean currents such as the Gulf Stream, can produce vast...

By Kristin S. Agostoni An artificial reef that was supposed to help bring surfable waves back to Dockweiler Beach is slated for removal within the coming weeks, ending an experiment that began more than a decade ago. The environmental group that constructed the V-shaped reef with 200 massive sandbags will start preparation Tuesday to pull the heavy sacks from the water, a spokesman said. Despite hopes that the country's first artificial surfing reef would generate waves in a once-popular...
