With an extended period of solar activity set to start as early as next year, storms originating from the sun could cause widespread blackouts and massive economic losses, a German insurance firm has predicted. The study, which was the work of Allianz, is the topic of a December 2 article by Reuters reporter Ethan Bilby which states that the "upcoming cycle of stormy solar activity risks causing damage to electrical transformers and threatening vulnerable energy infrastructure around the...

Image 1 - Erratic, Extreme Weather Puts Climate Change In New Light
2011-11-16 05:39:28

The first climate study to focus on variations in daily weather conditions has 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. Princeton University researchers recently reported in the Journal of Climate that extremely sunny or cloudy days are more common than in the early 1980s, and that swings from thunderstorms to dry days rose considerably since the late 1990s....

Image 1 - Proba-1 Celebrates 10 Years Of Charting Earth's Radiation Belts

ESA´s Proba-1 recently celebrated its tenth birthday in orbit. Kept busy as an Earth-observing mission, the microsatellite has also been building a detailed picture of changes in our planet´s radiation belts. Smaller than a cubic meter, the technology-testing Proba-1 was launched on 22 October 2001. Among the payloads was ESA´s SREM standard radiation environment monitor, which was turned on a week later. The size of a shoebox, the monitor records high-energy charged...

Drop In Radiation Can Trigger Cold Winters
2011-10-11 04:33:48

According to a new study, a drop in the sun's radiation can trigger unusually cold winters in parts of North America and Europe. The scientists said this finding could improve long-range forecasts and help countries prepare for blizzards. Previously, researchers were just able to see a weak link between solar activity and winter weather.  However, the new study used satellite measurements from NASA's Solar Radiation and Climate Experiment (SORCE) to reveal that differences in UV...

Image 1 - ESA Selects Next Two Science Missions
2011-10-04 11:53:02

The powerful influence of the Sun and the nature of the mysterious 'dark energy' motivate ESA´s next two science missions. Solar Orbiter and Euclid were selected today by ESA's Science Programme Committee for implementation, with launches planned for 2017 and 2019. These two missions are medium-class missions and are the first in ESA's Cosmic Vision 2015-2025 Plan. Solar Orbiter will venture closer to the Sun than any previous mission. It is designed to make major breakthroughs in...

Image 1 - Geomagnetic Storm Could Cause Unusual Aurora Activity
2011-09-27 09:42:00

[ Watch the Video ] NASA said on Monday that a "strong-to-severe" geomagnetic storm has hit Earth and could cause a rise in aurora borealis activity. The space agency said the sun unleashed an X1.9-category flare on Saturday morning, causing the geomagnetic storm to reach Earth at a Kp index of 9 in some places on Monday morning. The sun's "Active Region 1302" is the culprit in the incident.  Its bursts of radiation is so intense it could send auroras as far south as Colorado....

Researchers at Reading University said that solar storms are likely to become more disruptive to planes and spacecraft within decades. The team predicts that once the Sun shifts towards an era of lower solar activity, more hazardous radiation will reach Earth. The researchers said in Geophysical Research Letters that the Sun is currently at a grand solar maximum, which is a phase that began in the 1920s. Mike Lockwood, professor of space environment physics at Reading, said in a statement:...

As the Sun enters a period of low solar activity over the next 50 years, new research has calculated the probability of unusually cold winter temperatures occurring in the UK. Last year, the same group of researchers, from the University of Reading, linked colder winters in Europe to low solar activity and predicted that the Sun is moving into a particularly low period of activity, meaning the UK will experience more cold winters in the future "“ potentially similar to those experienced...

By Dr. Tony Phillips - Science@NASA In Sept. 1859, on the eve of a below-average1 solar cycle, the sun unleashed one of the most powerful storms in centuries. The underlying flare was so unusual, researchers still aren't sure how to categorize it.  The blast peppered Earth with the most energetic protons in half-a-millennium, induced electrical currents that set telegraph offices on fire, and sparked Northern Lights over Cuba and Hawaii. This week, officials have gathered at the National...

How Solar Cycles Impact Our Weather Here On Earth
2013-01-13 09:10:34

Solar cycles: what are they and why should we care about them? Solar cycles are made up of what are known as solar minimums (min) and solar maximums (max). We refer to a solar min at the time when the sun is not active with many sunspots, while a solar max is just the opposite when we see a large increase in sunspot activity. So how long do solar cycles last? Typically they run on what is known as an 11 year cycle from the max to the min and then start over again anew. As of 2012 we...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Honolulu Hawaii, during the month of March. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 48% efficient for the month, producing less than 50% of the month which is due to the large amount of daily cloud cover that is seen on the island during the early morning and...

Being a meteorologist for over thirteen years you start to take note of many things in the atmosphere and how they repeat themselves. Our Climate is no different. The definition of climate is stated as: the collective weather data in regards to moisture and temperature for over 30 years for the same location. So to better understand our climate we need to look at this. First, we have average temperatures for given places based on the 30 year average. Some years the temps are warmer or...

Incoming Solar Radiation Impacts By Various Weather Cycles

The above image looks at the month of March for the three cycles known as Normal Phase, El-Nino, and La-Nina. The data was recorded for the city of Austin Texas. Remember this is just data for one month during these cycles. Normal: During this cycle incoming solar activity was upwards to 60% efficient for the month, producing enough solar energy that only 40% of the month would have not had strong incoming radiation. EL-Nino: This phase provided the area with an extended number of...

Charles Greeley Abbot (May 31, 1872 "“ December 17, 1973) was an American astrophysicist and astronomer born in Wilton, New Hampshire. He graduated from Phillips Academy in 1891 and MIT in 1894, with a degree in chemical physics. In 1895 Abbot was hired by Samuel Pierpont Langley as an assistant at the Smithsonian Astrophysical Observatory (SAO) despite his lack of experience in astronomy. Hired originally for his laboratory skills, Abbot became acting director of the SAO in 1896. When...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
