First ATTREX Science Mission Completed By NASA
2014-02-14 14:59:40

Beth Hagenauer - NASA NASA's Global Hawk No. 872 completed a 17.5-hour science flight Feb. 14, it's first for the 2014 Airborne Tropical Tropopause Experiment (ATTREX) mission. The unmanned aircraft, carrying a suite of specialized instruments, flew from Andersen Air Force Base on the island of Guam. Objectives were to sample vertical distribution of the Western Pacific tropical tropopause layer trace gases, water vapor and clouds. In situ data was gathered about cirrus clouds in the...

NCAR scientists and partners next week will launch a field project in the tropical Pacific, a remote region that holds a key to understanding worldwide climate. The warm waters fuel huge clusters of thunderstorms that act as a global chimney, lofting gases and particles into the stratosphere and affecting the planet. Boulder, CO (PRWEB) January 07, 2014 Even though few people live in the western tropical Pacific Ocean, these remote waters affect billions of people by shaping climate and...

Mystery Of Troposphere Warming Solved
2013-12-10 14:44:32

Lee Rannals for redOrbit.com - Your Universe Online A long-standing mystery surrounding unusual warming of planetary atmospheres is not just exclusive to our solar system, but is most likely universal, according to a paper published in the journal Nature Geoscience. In 1902 a scientist named Léon Teisserenc de Bort found a point in Earth’s atmosphere where the air stops cooling and begins growing warmer. This finding was surprising considering scientists knew that as you climb in...

Climate Change Clues Could Come From The Stratosphere

redOrbit Staff & Wire Reports - Your Universe Online NASA has announced plans to send an unmanned, remotely-controlled research vehicle into the upper atmosphere in order to find out what impact climate change is having on our planet. The program, which has been christened the Airborne Tropical Tropopause Experiment (ATTREX), will utilize instruments on board a long-range Global Hawk aircraft to collect measurements above the tropical Pacific Ocean, the US space agency explained....

Scientists To Study Thunderstorm Effects On Upper Atmosphere
2012-05-02 03:56:14

Research examines how thunderstorm structure and cloud chemistry interact Scientists are targeting thunderstorms in Alabama, Colorado and Oklahoma this spring to discover what happens when clouds suck air many miles into the atmosphere from Earth's surface. The Deep Convective Clouds & Chemistry (DC3) Experiment, which begins in mid-May, will explore the influence of thunderstorms on air just beneath the stratosphere, a region that influences Earth's climate and weather patterns....

Pyrocumulonimbus is the fire-breathing dragon of clouds. A cumulonimbus without the "pyre" part is imposing enough -- a massive, anvil-shaped tower of power reaching five miles (8 km) high, hurling thunderbolts, wind and rain. Add smoke and fire to the mix and you have pyrocumulonimbus, an explosive storm cloud actually created by the smoke and heat from fire, and which can ravage tens of thousands of acres. And in the process, "pyroCb" storms funnel their smoke like a chimney into Earth's...

New research suggests intertwining of tropical cyclones, climate changeScientists at Harvard University have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming.The finding, published in Geophysical Research Letters, provides more evidence of the intertwining of severe weather and global warming by demonstrating a mechanism by which storms could drive climate change. Many scientists now believe that global warming, in turn, is likely to...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
