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....

Image 1 - Is Fertilizer To Blame For Global Warming?
2012-04-04 07:02:15

Chemists from the University of California, Berkeley have discovered evidence of a link between increased fertilizer use and a rise in atmospheric nitrous oxide, a major greenhouse gas. Climate scientists have long assumed the cause of rising nitrous oxide levels in the atmosphere was due in part to nitrogen-based fertilizers. Such fertilizers are used to stimulate microbes in the ground to convert nitrogen to nitrous oxide at a faster rate. Published in the April issue of the journal...

2012-03-28 08:43:58

RedOrbit Meteorologist Joshua Kelly In this edition we will be examining what is known as a Upper Air Weather Code and why it´s so important to weather forecasting. First what is an upper air code? An upper air code is used to determine the weather conditons of the atmosphere above us. Throughout the world many weather organizations release weather balloons twice a day into the atmosphere. These balloons then bring back data from the upper air just as you see in the code...

Image 1 - The Surprising Power Of A Solar Storm

[ Watch the Video ] Solar storm dumps gigawatts into Earth's upper atmosphere A recent flurry of eruptions on the sun did more than spark pretty auroras around the poles.  NASA-funded researchers say the solar storms of March 8th through 10th dumped enough energy in Earth´s upper atmosphere to power every residence in New York City for two years. “This was the biggest dose of heat we´ve received from a solar storm since 2005,” says Martin Mlynczak of...

Earth's Prehistoric Multiple Atmospheres

Earth´s early atmosphere may have flipped between two sates before oxygenation, according to a new study. Researchers at Newcastle University have published these findings in the journal Nature Geoscience. They found Earth´s early atmosphere would switch between a hydrocarbon-free state and a hydrocarbon-rich state. This kind of atmosphere, according to the researchers, is similar to that of Saturn´s moon, Titan. Referring to the two states as “organic haze”...

Clouds have a profound effect on the climate, but we know surprisingly little about how they form. Erika Sundén, researcher at the University of Gothenburg, Sweden, has studied how extremely small cloud particles can dispose of excess energy. This knowledge is necessary to understand processes in the atmosphere that affect global climate change. The models that have been built to describe climate change contain a major source of uncertainty, namely the effects of clouds. The...

Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colo., released a study claiming that inconsistencies between satellite observations of Earth's heat and measurements of ocean heating amounted to evidence of "missing energy" in the planet's system. Where was it going? Or, they wondered, was something wrong with the way researchers tracked energy as it was absorbed from the sun and emitted back into space? An international team of atmospheric...

Atmospheric methane (CH4), one of the main greenhouse gases, has increased dramatically worldwide since the pre-industrial era. However, much work is needed to build on intermittent and scattered observations since the 1960s and systematic study since the 1980s. Since 1983, the World Meteorological Organization (WMO) has coordinated global in-situ measurement of methane. Quantification of methane emissions still has large uncertainties, mainly because of undersampling over most regions of the...

Low Temperatures Enhance Ozone Degradation Above The Arctic
2012-01-20 05:29:14

KIT Climate Researchers Studied Ozone Hole Formation - Results in “Geophysical Research Letters“ Extraordinarily cold temperatures in the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far: The mechanisms leading to the first ozone hole above the North Pole were studied by scientists of the KIT Institute of Meteorology and Climate Research (IMK). According to these studies, further cooling of the ozone layer may enhance the...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Important things to know when it comes to weather are the terms that a meteorologist uses on the television, radio or on a weather website.  The first term is Return flow. Sometimes you will hear a meteorologist use this term. The best way to understand this is to look at a weather map. When you see a High pressure center which is the blue H, look to the western side of that high pressure. This is where the warm moist air starts moving from the south back towards the north, which is why it...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

Earth's Atmosphere

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
