Scientists analyzed 40 years of daily weather data to understand the NAO's two-week cycle and its effects on European winters. They found that positive NAO events lead to milder winters, while negative events bring colder temperatures and more precipitation.
A recent Asian dust storm triggered a massive bloom of phytoplankton in the North Pacific, suggesting that wind-blown iron from terrestrial dust can stimulate plankton growth. This observation challenges the long-held 'iron hypothesis,' which proposed that adding iron to ocean waters could offset global warming.
A new theory suggests that the Earth's surface features can be explained by rapid changes in crustal plate direction due to convection in the mantle. The research uses powerful computer systems to model the Earth's interior in three dimensions, revealing dynamic processes that shape our planet.
Researchers found thicker, denser storm clouds over warmer waters, covering wider areas of the tropics and releasing more moisture as rain. This contradicts the 'Adaptive Iris' theory, which suggests cloud cover decreases with rising ocean temperatures.
Researchers have developed a new technique that predicts Madden-Julian Oscillations (MJOs), which can provide two-weeks notice for storms. This allows scientists to issue storm warnings weeks earlier than current conventional weather forecasting, supporting sustainable development efforts.
The American College of Emergency Physicians has issued first consensus guidelines on lightning safety before summer storms. These guidelines emphasize the importance of individual responsibility in avoiding lightning injury and provide tips on safer practices, including knowing safe locations and following weather updates.
A U. of Colorado-led science team is studying environmental problems on Alaska's North Slope to better understand and mitigate the effects of climate variability and potential environmental disasters. The researchers are creating a storm damage handbook using computer modeling to help local communities prepare for extreme storms.
Research suggests that seawalls may have no significant long-term effect on beach behavior, despite causing active erosion during storms. Geologists consider factors such as sediment transport rates and beach erosion to determine net long-term erosion.
Research shows waves in southern California and the North Pacific have increased in size and intensity over the past half century due to stronger wind and storm activity. The approach direction of winter ocean swells has rotated from northwesterly to westerly, reducing natural sheltering effects and increasing direct impacts on the coast.
NASA's Mars Global Surveyor and Hubble Space Telescope provide a unique view of the largest global dust storm on Mars in several decades. The storm, which has engulfed the entire planet for three months, raises questions about Mars' thin atmosphere and climate change.
Scientists have observed a sudden shift in Mars' atmosphere, with temperatures increasing by about 30 degrees Centigrade, due to a massive dust storm. This phenomenon is similar to Earth's global warming, but much more extreme and potentially leading to a significant cooling of the planet.
Researchers found a strong correlation between the Arctic Oscillation's negative phase and near-record cold days and snow storms over a broader region of the hemisphere. The Arctic Oscillation has been linked to wide-ranging climate effects in the Northern Hemisphere, preventing freezing temperatures from extending as far south.
A University of Washington researcher found that climbers using supplemental oxygen on Mount Everest had a 3% death rate during descent, compared to an 8.3% death rate for those not using oxygen. A similar pattern emerged on K2, where none of the successful climbers who used supplemental oxygen died during descent.
Spann will present the latest information from the UltraViolet Imager project, which studies how space storms develop and affect Earth's space environment. The presentation aims to provide insights into directly driven auroral signatures resulting from interplanetary pressure points.
Scientists observed solar activity directly affecting Earth's outer atmosphere, causing auroral light displays. The Polar satellite measured the effects of a massive solar storm that pumped 200 gigawatts of energy into Earth's atmosphere.
Scientists have captured the most insightful images to date of Neptune's wildest weather, including monster storms and equatorial winds of 900 miles per hour. The new observations revealed a
The Leonid meteor storm may pose a significant threat to satellites due to the high likelihood of invisible meteors. Astronomers predict that most meteors will burn up at low temperatures, making them undetectable.
A major geomagnetic storm, the strongest in recent years, is affecting communication and navigation satellites due to an intense solar flare. The storm's speed was twice normal, causing unusual penetration of electrons into the Earth's magnetosphere.
A study by Cornell University researchers found that most buildings in the Northeast region exceeded minimum building code requirements for snow loads during the Blizzard of '96. The accumulation of snow from two storms led to increased snow weight on roofs, causing collapses in some areas.
A new weather-forecasting system using a powerful Sun Microsystems computer is providing the Pacific Northwest region with highly accurate temperature and wind forecasts. The system helps predict weather patterns such as snow, rain, and precipitation, enabling agencies to prepare for extreme weather events and issue air-quality alerts.
A field program, FASTEX, investigates connections between coast-to-coast winter storms and Atlantic Ocean storms to enhance forecasting for both Europe and North America. The project aims to identify precursors that trigger cyclones, enabling better forecasts up to two or three days in advance.
Lee Marshall, a Penn State graduate student, captures electromagnetic signals of sprites and elves, which are optical phenomena caused by ionized nitrogen above thunderheads. The project uses automatic alert systems to detect these signals, which last only milliseconds and microseconds.
Scientists at Boston University have captured high-resolution images of the Earth's outer atmosphere using the POLAR ENA Imaging Proton Spectrometer. These images allow for the tracking of magnetic storms in space and provide new insights into the relationship between the Sun and Earth.
Researchers developed a new sediment basin design that reduces silt removal by using a skimmer system. The system removed 37 pounds of soil during simulated events, outperforming other methods tested.
Researchers at NCAR have developed new computer models to analyze storm development and forecast uncertainty. The auto-nowcaster tool, which spots incipient storms and predicts their development up to a half-hour in advance, will be tested this summer.
