Lightning Strikes May Be More Intense Due To Solar Wind Activity
2014-05-16 12:40:11

Brett Smith for redOrbit.com - Your Universe Online From the ancient Greeks to Benjamin Franklin, man has long been fascinated by lightning. Previous research has found that the electrical bolts are caused by cosmic radiation and a new study has found that streams of high-energy particles from the Sun accelerated by the solar wind also play a role. Published in the journal Environmental Research Letters, the new study revealed a considerable raise in lightning rates throughout Europe...

When talking about lightning, appearances of different lightning which occur along with thunderstorms will emerge in the minds of the people and these lightning occur in the troposphere. However, in addition to lightning in the troposphere, there are kinds of lightning discharges which occur above the thunderstorms. Up to now, lightning discharges above storms include sprite, elves (Emissions of Light and VLF perturbation due to EMP Sources, elves), Blue jet and Gigantic jet etc, and all of...

Shuttle Exhaust Reveals More About Atmospheric Winds

April Flowers for redOrbit.com - Your Universe Online The last space shuttle flight took place on July 8, 2011, sending Atlantis into space for its thirty-third, and final mission. This flight marked the end of a 20-year space shuttle program. As Atlantis reached a height of about 70 miles over the east coast of the U.S., it released 350 tons of water vapor exhaust. The vapor plume spread and floated on air currents high in the Earth's atmosphere, crossing through the observation paths...

Clouds play a major role in the climate-change equation, but they are the least-understood variable in the sky, observes a Texas A&M University geoscientist, who says mid-level clouds are especially understudied. The professor, Shaima Nasiri, is making those "in-between" clouds the focus of her research, which is being funded by NASA. Mid-level clouds are so understudied, Nasiri says, that scientists have yet to develop a common nomenclature for them. "We do not have a unified definition,...

NASA's Aeronomy of Ice in the Mesosphere (AIM) satellite has captured five complete polar seasons of noctilucent (NLC) or "night-shining" clouds with an unprecedented horizontal resolution of 3 miles by 3 miles. Results show that the cloud season turns on and off like a "geophysical light bulb" and they reveal evidence that high altitude mesospheric "weather" may follow similar patterns as our ever-changing weather near the Earth's surface. These findings were unveiled Dec. 15 at the Fall...

Clemson University space physicists have traveled around the world to launch rockets to test atmospheric conditions. Scientists most recently launched a salvo of four rockets over Alaska to study turbulence in the upper atmosphere. The launches took place at Poker Flat Research Range north of Fairbanks as part of a NASA sounding rocket campaign. Associate professor of physics and astronomy Gerald Lehmacher is the principal investigator for the experiment and was assisted by graduate students...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
