Scientists have developed a new computer modeling technique that offers the promise, for the first time, of producing continually updated daylong predictions of wildfire growth throughout the lifetime of long-lived blazes. The technique, developed by a research team led by NCAR, combines detailed computer simulations with newly available satellite observations. Boulder, CO (PRWEB) November 14, 2013 Scientists have developed a new computer modeling technique that offers the promise, for...

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...

China´s Olympian attempt to improve air quality during the 2008 summer games did more than provide a healthier atmosphere for the athletes. It also demonstrated that widespread changes in transportation patterns could greatly reduce the threat of climate change. New research by an international team of scientists led by the National Center for Atmospheric Research (NCAR) indicates that China´s restrictions on motor vehicles had the side benefit of dramatically cutting emissions...

Eemian Period Is A Poor Analogue For Current Climate Change
2012-06-15 04:34:14

The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal “Geophysical Research Letters” scientists from Mainz, Kiel and Potsdam (Germany) now present evidence that the Eemian differed in essential details from modern climatic conditions. Joint press release of the Academy of the Sciences and the Literature Mainz and the GEOMAR | Helmholtz Centre for Ocean Research Kiel. To address...

Stream Temperatures Don’t Parallel Warming Climate Trend
2012-05-03 03:33:31

A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate. Several factors may influence the discrepancy, researchers say, including snowmelt, interaction with groundwater, flow and discharge rates, solar radiation, wind and humidity. But even after factoring out those elements, the scientists were surprised by the...

Cassini Detects Oxygen On Saturn's Moon Dione
2012-03-02 13:18:55

Researchers report this week in the journal Geophysical Research Letters that NASA's Cassini spacecraft has detected oxygen on one of Saturn's moons. They said their finding increases the likelihood of finding the ingredients for life on one of the moons orbiting gas giants. The ice moon, Dione, has no liquid water and does not have the proper conditions to support life, Andrew Coates of the University College London said.  However, he said that it is possible that other moons of...

Could Salty Soil Suck Water Out Of The Martian Atmosphere?
2012-02-29 03:51:57

The frigid McMurdo Dry Valleys in Antarctica are a cold, polar desert, yet the sandy soils there are frequently dotted with moist patches in the spring despite a lack of snowmelt and no possibility of rain. A new study, led by an Oregon State University geologist, has found that that the salty soils in the region actually suck moisture out of the atmosphere, raising the possibility that such a process could take place on Mars or on other planets. The study, which was supported by the...

Deep-diving ocean "gliders" have revealed the journey of Bass Strait water from the Tasman Sea to the Indian Ocean. Deployed in 2010 and 2011, the gliders have also profiled a 200-metre tall wall of water at the core of long-lived ocean eddies formed from the East Australian Current.The study, by University of Technology Sydney and CSIRO oceanographers, revealed the value of new sensors being deployed by Australia's Integrated Marine Observing System. "We're getting a terrific amount of...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
