Lee Siegel, University of Utah Global warming may bring more curvy jet streams during winter Last winter's curvy jet stream pattern brought mild temperatures to western North America and harsh cold to the East. A University of Utah-led study shows that pattern became more pronounced 4,000 years ago, and suggests it may worsen as Earth's climate warms. "If this trend continues, it could contribute to more extreme winter weather events in North America, as experienced this year with...

Climate Change Hidden Impacts Detailed In New Moth Study
2014-04-15 09:11:36

Brett Smith for redOrbit.com - Your Universe Online A new climate change study conducted on sub-Arctic moths living in Finland has revealed mixed results: moths seem to be thriving despite a warmer, wetter climate – while an as-yet-unknown force is apparently masking the expected effects of this localized climate change. "You see it getting warmer, you see it getting wetter and you see that the moth populations are either staying the same or going up. So you might think, 'Great. The...

Woods Hole Research Center Future simulations of climate in the Amazon suggest a longer dry season leading to more drought and fires. Woods Hole Research Center scientists Michael Coe, Paulo Brando, Marcia Macedo and colleagues have published a new study on the impacts of fire and drought on Amazon tree mortality. Their paper entitled “Abrupt increases in Amazonian tree mortality due to drought-fire interactions,” published in the Proceedings of the National Academy of Sciences, found...

Rise in Snowpack Feeding Colorado River Minor in Long-Term Drought Las Vegas, NV (PRWEB) April 14, 2014 While the snowpack that feeds the Colorado River is expected to produce 5 percent more water this year, noted climatologist Evelyn Browning-Garriss of the Browning Newsletter says the main event that could bring more serious relief from the Western drought is a potential El Nino brewing in the Pacific. “California is seeing snowpack that is 23 percent of normal and the state’s...

New report describes climate change risks for northern Michigan forests In the last 100 years, Michigan has become warmer, with more rain coming through heavy downpours. Climate models suggest that the state will continue to warm and variability in precipitation patterns will increase, which will have consequences for the state’s forests. A new U.S. Forest Service report describes the potential risks and opportunities of climate change for forests in the eastern Upper Peninsula and...

Statistical analysis rules out natural-warming hypothesis with more than 99 percent certainty An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth's climate, according to a new study by McGill University physics professor Shaun Lovejoy. The study, published online April 6 in the journal Climate Dynamics, represents a new approach to the question of whether global warming in the...

Animal shelters, zoos, and aquariums benefit from daylighting initiatives. Vista, CA (PRWEB) April 11, 2014 Doesn’t everyone deserve daylight? Animal, plants and people all need natural light to survive and thrive. Few things say “Earth Day” the way daylight does – one company that is highly committed to changing the way we think about and use daylight is Solatube International, the worldwide leading manufacturer and marketer of Tubular Daylighting Devices (TDDs). In honor of...

The release will occur at the SPAR International 3D Measurement & Imaging Conference, which will be held from April 14 to April 17, 2014, in Colorado Springs, Colorado. VeloView is a free open-source application built on ParaView technology. It is designed for the visualization and analysis of point cloud data...

stratospheric ozone intrusion
2014-04-11 13:12:51

[ Watch the Video: Ozone-Rich Air Descends From On High ] Kathryn Hansen, NASA's Earth Science News Team Outdoor enthusiasts in Colorado's Front Range are occasionally rewarded with remarkable visibility brought about by dry, clear air and wind. But it's what people in the mountainous U.S. West can't see in conditions like this – ozone plunging down to the ground from high in the stratosphere, the second layer of the atmosphere – that has attracted the interest of NASA scientists,...

noctilucent clouds
2014-04-11 10:36:00

Karen C. Fox, NASA's Goddard Space Flight Center First spotted in 1885, silvery blue clouds sometimes hover in the night sky near the poles, appearing to give off their own glowing light. Known as noctilucent clouds, this phenomenon began to be sighted at lower and lower latitudes -- between the 40th and 50th parallel -- during the 20th century, causing scientists to wonder if the region these clouds inhabit had indeed changed -- information that would tie in with understanding the weather...

Urban Heat Island
2013-04-02 15:35:21

An urban heat island (UHI) is a metropolitan area that is drastically warmer than its surrounding rural areas because of human activities. The phenomenon was first looked into and described by Luke Howard during the 1810s, although he wasn’t the one to name the phenomenon. The difference in temperature is normally bigger at night as opposed to during the day, and it most obvious when winds are weak. Seasonally, UHI is seen during the summer and the winter. The key cause of the urban heat...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
