One tornado can be damaging enough; severe weather systems that spawn hundreds of deadly tornadoes in super-outbreaks pose special challenges to the scientific and emergency management communities. Now, scientists have identified certain conditions in the Pacific Ocean that may lead to super-outbreaks over the U.S.' tornado alley. Researchers are trying to determine if Trans-Niño years, which mark the onset or ebbing of El Niño and La Niña, are the main culprits behind the deadly...

La Nada Event In Pacific
2013-09-10 15:37:20

Brett Smith for redOrbit.com - Your Universe Online Based on data from one of NASA’s orbiting satellites, experts at the National Weather Service’s Climate Prediction Center have found near-normal sea-surface height conditions across the equatorial Pacific Ocean, indicative of a so called “La Nada” event. The weather experts added that the condition has persisted for 16 months, since spring 2012 and will continue through the spring of 2014. “Without an El Niño or La Niña...

Skyscraper-Size Waves Circulate Energy, Nutrients In Deep Ocean
2013-09-09 15:51:47

Brett Smith for redOrbit.com - Your Universe Online While massive waves are a surfer’s dream, they are also fascinating to oceanographers – particularly those waves breaking deep in the ocean. These deep ocean waves play a vital role in long-term climate cycles and a new study from scientists at the University of Washington has revealed waves the height of skyscrapers circulating energy and nutrients deep below the Southern Pacific Ocean. “Climate models are really sensitive...

West Antarctica's Ice Sheet 20 Million Years Older Than Previosuly Estimated
2013-09-05 07:26:16

April Flowers for redOrbit.com - Your Universe Online A research team led by professors at the University of California Santa Barbara (UCSB) has revealed that, contrary to popular belief, an ice sheet on West Antarctica existed 20 million years earlier than previously thought. These results, published in Geophysical Research Letters, mark a paradigm shift for our understanding of the Earth’s great global ice sheets. Ice sheets first grew on the West Antarctic subcontinent around 34...

Shocking Reefs Back To Life
2013-09-02 10:56:39

Brett Smith for redOrbit.com - Your Universe Online Major weather events can shock an ecosystem, but they are also part of Earth’s natural cycle, and many species are adept at recovering from an environmental shake up. New research from a joint team of Australian and Swedish researchers has shown that ecosystem shocks caused by changing climate or seasons could play a key role in bringing back some of the world’s badly degraded coral reefs, according to a new report in the journal...

Rising Sea Waters Threaten Hawaiian Shorelines
2013-08-31 08:19:16

April Flowers for redOrbit.com - Your Universe Online In Hawaii, sea-level rise (SLR) has been isolated as a principal cause of coastal erosion. After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on the islands of Oahu and Maui. A new study,...

Acoustic Wave Tsunami Warning System
2013-08-29 13:34:12

[ Watch the Video: What is a Tsunami? ] Peter Suciu for redOrbit.com – Your Universe Online While the waves from a tsunami can be extremely destructive, acoustic waves could help warn of the impending danger. Not much can be done to actually stop these natural disasters, but the earlier a warning goes out that a tsunami could strike the coast, the better the chances of effectively evacuating the area. Early warning systems play a critical role in ensuring that people reach safety,...

Coral Reef Biodiversity More Important To Divers Than Fish Abundance

[WATCH VIDEO: Tamar Artificial Reef Now Teeming With Life] Brett Smith for redOrbit.com - Your Universe Online With ecotourism on the rise, determining what elements of a nature-based attraction are most appealing can have significant consequences financially and for raising awareness of conservation issues. In a new study of the Negev from Ben-Gurion University (BGU) in Israel, researchers found that divers were able to differentiate between an artificial reef’s biodiversity and...

When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by the National Center for Atmospheric Research (NCAR) shows that when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably. Unlike other continents, the soils and topography of Australia prevent almost all of its precipitation from running off into the...

Smallest Continent Had Biggest Role In Sea Level Drop
2013-08-20 08:53:03

NASA A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise during that time, finds a new study co-authored and co-funded by NASA. In 2011, scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the University of Colorado at Boulder reported that between early 2010 and summer 2011, global sea level fell sharply, by about a...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...
