Less summer Arctic sea ice cover means colder, snowier winters in Central Europe
Even if the current weather situation may seem to go against it, the probability of cold winters with a lot of snow in Central Europe rises when the Arctic is covered by less sea ice in summer.
Sun unleashes an X1.8 class flare on Jan. 27, 2012
The sun unleashed an X1.8 class flare that began at 1:12 PM ET on January 27, 2012 and peaked at 1:37. The flare immediately caused a strong radio blackout at low-latitudes, which was rated an R3 on NOAA's scale from R1-5. The blackout soon subsided to a minor R1 storm. Models from NASA's Goddard Space Weather Center predict that the CME is traveling at over 1500 miles per second. It does not initially appear to be Earth-directed, but Earth may get a glancing blow.

NASA renames Earth-observing mission in honor of satellite pioneer
NASA has renamed its newest Earth-observing satellite in honor of the late Verner E. Suomi, a meteorologist at the University of Wisconsin who is recognized widely as "the father of satellite meteorology." NASA launched the National Polar-orbiting Operational Environmental Satellite System Preparatory Project, or NPP, on Oct. 28, 2011, from Vandenberg Air Force Base in California. NPP was renamed Suomi National Polar-orbiting Partnership, or Suomi NPP. The satellite is the first designed to collect critical data to improve short-term weather forecasts and increase understanding of long-term climate change.
Classifying solar eruptions
Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). While these are the most common solar events, the sun can also emit streams of very fast protons -- known as solar energetic particle (SEP) events -- and disturbances in the solar wind known as corotating interaction regions (CIRs). All of these can produce a variety of "storms" on Earth that can -- if strong enough -- interfere with short wave radio communications, GPS signals, and Earth's power grid, among other things.
Space weather arrives: Relatively minor impacts expected from solar storm
A significant blast of energy from the sun arrived at Earth on Jan. 24, 2012 at 10 a.m. EST, triggering a moderate geomagnetic storm here that's unlikely to cause major problems. But skywatchers take note: the storm could set off bright Northern and Southern lights Tuesday night, possibly visible from as far south as New York and Oregon.
Strongest solar radiation storm since 2005
NOAA's Space Weather Prediction Center -- the nation's official source of warnings and alerts about space weather and its impacts on Earth -- has issued a watch for a geomagnetic storm associated with a bright flare on the sun Sunday evening (Jan. 22, 2012). The storm could arrive Tuesday morning, with possible impacts to navigation, the power grid and satellites.

NASA sees repeating La Niña hitting its peak
La Niña, "the diva of drought," is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA's Jason-1 and -2 satellites show that the milder repeat of last year's strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean.
Toward twister forecasting: Scientists make progress in assessing tornado seasons
A new study of short-term climate trends offers the first framework for predicting tornado activity up to a month out with current technology, and possibly further out as climate models improve, giving communities a chance to plan. The study may also eventually open a window on the question of whether tornadoes are growing more frequent due to long-term climate warming.
Does La Niña weather pattern lead to flu pandemics?
Worldwide pandemics of influenza caused widespread death and illness in 1918, 1957, 1968 and 2009. A new study examining weather patterns around the time of these pandemics finds that each of them was preceded by La Niña conditions in the equatorial Pacific. Since the La Niña pattern is known to alter the migratory patterns of birds, the scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.

Helping wild horses and livestock survive extreme weather in Gobi desert
Winters in the Gobi desert are usually long and very cold but the winter of 2009/2010 was particularly severe, a condition Mongolians refer to as "dzud". Millions of livestock died in Mongolia and the re-introduced wild Przewalski's horse population crashed dramatically. Researchers have used spatially explicit loss statistics, ranger survey data and GPS telemetry to provide insights into the effect of a catastrophic climate event on wild horses, wild asses and livestock that share the same habitat but show different patterns of spatial use.
Weather deserves medal for clean air during 2008 Olympics
New research suggests that China's impressive feat of cutting Beijing's pollution up to 50 percent for the 2008 Summer Olympics had some help from Mother Nature. Rain just at the beginning and wind during the Olympics likely contributed about half of the effort needed to clean up the skies, scientists found. The results also suggest emission controls need to be more widely implemented than in 2008 if pollution levels are to be reduced permanently.
Ramping up wind energy research
As the percentage of wind energy contributing to the power grid continues to increase, the variable nature of wind can make it difficult to keep the generation and the load balanced. But recent work may help this balance through a project that alerts control room operators of wind conditions and energy forecasts so they can make well-informed scheduling decisions. This is especially important during extreme events, such as ramps, when there is a sharp increase or decrease in the wind speed over a short period of time, which leads to a large rise or fall in the amount of power generated.
Developing crops that can cope with sudden changes in the weather
Crops that can cope with sudden fluctuations in the weather could be developed, thanks to fresh discoveries about the survival mechanisms of plants.
Rose torture: Severe heat in Texas yields better varieties for research

People matter in climate change models
Climate change does not discriminate among regions or their inhabitants, but the continued growth of the human population will most likely contribute to the ill-effects of climate change. US researchers suggest an interdisciplinary approach, recruiting expertise from the social sciences, is best for conducting the needed research and model development to move forward in the study of climate change.
Gone with the wind: Why the fast jet stream winds cannot contribute much renewable energy after all
The assumption that high jet steam wind speeds in the upper atmosphere correspond to high wind power has now been challenged by new research. Taking into account that the high wind speeds result from the near absence of friction and not from a strong power source, scientists found that the maximum extractable energy from jet streams is approximately 200 times less than reported previously.

Erratic, extreme day'to-day weather puts climate change in new light
Researchers report the first climate study to focus on variations in daily weather conditions, which found that day-to-day weather has grown increasingly erratic and extreme, with significant fluctuations in sunshine and rainfall affecting more than a third of the planet. These swings could have consequences for ecosystem stability and the control of pests and diseases; industries such as agriculture and solar-energy production; and could affect what scientists can expect to see as the Earth's climate changes.
Air pollution a culprit in worsening drought and flooding
Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons. This while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons, according to results of a new study.
Rising air pollution worsens drought, flooding, new study finds
Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons, says a new study. The research provides the first clear evidence of how aerosols can affect weather and climate, with important economic and water resource implications.
2012: Killer solar flares are a physical impossibility, experts say
Given a legitimate need to protect Earth from the most intense forms of space weather ? great bursts of electromagnetic energy and particles that can sometimes stream from the sun ? some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth. Citing the accurate fact that solar activity is currently ramping up in its standard 11-year cycle, there are those who believe that 2012 could be coincident with such a flare. But this same solar cycle has occurred over millennia. Anyone over the age of 11 has already lived through such a solar maximum with no harm. In addition, the next solar maximum is predicted to occur in late 2013 or early 2014, not 2012.

Laying the blame for extreme weather
Floods, tornadoes, droughts and wildfires: They are all weather-related, but blaming the latest meteorological disaster on climate change has always been a tricky matter that climate scientists have been shy to do. After all, how can you point to a specific and local event, such as a tornado or dry spell, and say it is caused by something as long-term and huge as global warming?
Thanks for your kind support!
