Atlantic Ocean Dances With The Sun And Volcanoes
2014-04-01 09:06:11

By Christina Troelsen, Aarhus University Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere. These fluctuations are the result of a complex dance between the forces of nature, but researchers at Aarhus University can now show that solar activity and the impact of volcanic eruptions have led this dance during the last two centuries. Imagine a ballroom in which two dancers apparently keep in time to...

With the 2014 tornado season dead ahead, 53-year-old Steve Green, a former NASCAR driver, plans to elevate his adrenaline level to even greater heights by walking into a tornado and...

Final Joplin Tornado Report Issued By NIST
2014-03-31 13:56:17

NIST The National Institute of Standards and Technology (NIST) has released the final report on its technical investigation into the impacts of the May 22, 2011, tornado that struck Joplin, Mo. The final report is strengthened by clarifications and supplemental text suggested by organizations and individuals from across the nation in response to the request for comments on the draft Joplin report, released Nov. 21, 2013. The revisions did not alter the investigation team's major...

Pioneering new research from the University of Exeter could have a major impact on climate and environmental science by drastically transforming the perceived reliability of key observations of precipitation, which includes rain, sleet and snow. The ground breaking study examines the effect that increased aerosol concentrations in the atmosphere, emitted as a result of burning fossil fuels, had on regional temperature and precipitation levels. Scientists from Exeter's Mathematics...

April Flowers for redOrbit.com - Your Universe Online During the Northern Hemisphere's growing season, data returned from satellite sensors shows that the Midwest has more photosynthetic activity than any other region of the planet, according to a recent NASA report. School children are taught that plants convert light to energy through the process of photosynthesis. What is less known, however, is that chlorophyll also emits a fraction of the absorbed light as fluorescent glow, which...

--Removable, Barrier Flood Wall Installed at 55 Water Street - NEW YORK, March 31, 2014 /PRNewswire/ -- Directly following Hurricane Sandy in October 2012, Plaza Construction was asked to start working on the development of a flood prevention solution for 55 Water Street, one of New York City's largest office structures with 54 stories and 3.8 million square feet located in the financial district. Hurricane Sandy was the second-costliest storm in U.S. history with damages to New...

Satellite Time-Lapse Animation Shows US East Coast Snowy Winter
2014-03-28 12:05:26

[ Watch The Video: GOES Satellite Movie of 2014 Winter Storms ] Rob Gutro, NASA A new time-lapse animation of data from NOAA's GOES-East satellite provides a good picture of why the US East Coast experienced a snowier than normal winter. The new animation shows the movement of storms from January 1 to March 24. NOAA's Geostationary Operational Environmental Satellites or GOES-East imagery from January 1 to March 24 was compiled into three videos made by NASA/NOAA's GOES Project...

Test shows it could have accurately forecasted flooding in NYC during Sandy The water that surged into the intersection of New York City’s Canal and Hudson streets during Hurricane Sandy—to choose just one flood-ravaged locale—was ultimately driven ashore by forces swirling hundreds of miles out in the Atlantic. That simple fact shows not only the scale and power of a tropical cyclone, but the difficulty of modeling and forecasting its potential for coastal flooding on the fine...

LAS VEGAS, March 26, 2014 /PRNewswire/ -- GeoMetWatch (GMW) announced that it has entered into an agreement with Exelis, a top-tier diversified global aerospace company that builds advanced weather satellite sensors, to design a geostationary hyperspectral sounder. Under the terms of the agreement, Exelis would manufacture sensors to be hosted by GMW partner organizations through a GMW license granted by the Department of Commerce to deploy a constellation of six geostationary...

In a head-spinning announcement the UN’s World Meteorological Organization issued statements claiming extreme weather events of the past year were consistent with human-induced climate change, directly contradicting the Intergovernmental Panel on Climate Change AR5 report issued in September 2013 which states that there is a hiatus in global warming and that there has been no observed global trend in tropical storms, hurricanes, droughts or floods. Friends of Science point to...

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...
