Asthma epidemics linked to airflow patterns in thunderstorms
It's the airflow patterns in thunderstorms, rather than the electrical activity, thunder, or rain, which trigger asthma epidemics, concludes research in Thorax. The hospital admission rates for asthma and airflow patterns during thunderstorms up to 80 km away were studied for six towns in south... view more (2001-05-16)

Tibet Provides Passage for Chemicals to Reach the Stratosphere
NASA and university researchers have found that thunderstorms over Tibet provide a main pathway for water vapor and chemicals to travel from the lower atmosphere, where human activity directly affects atmospheric composition, into the stratosphere, where the protective ozone layer resides.   view more (2006-05-10)

Link shown between thunderstorms and asthma attacks in metro Atlanta area
In the first in-depth study of its kind ever done in the Southeastern United States, researchers at the University of Georgia and Emory University have discovered a link between thunderstorms and asthma attacks in the metro Atlanta area that could have a "significant public health impact."   view more (2008-07-11)

New Models of Weather Pattern
For a mathematician, Joseph Biello spends a lot of time thinking about the weather. But the UC Davis assistant professor isn't looking out the office window. He is using mathematical theory to build a model of the Madden-Julian Oscillation, a tropical weather pattern that influences drought and... view more (2005-12-12)

NASA satellite finds the world's most intense thunderstorms
A summer thunderstorm often provides much-needed rainfall and heat wave relief, but others bring large hail, destructive winds, and tornadoes. Now with the help of NASA satellite data, scientists are gaining insight into the distribution of such storms around much of the world.   view more (2006-10-26)

Documenting a paradox: smoke decreases rainfall but ultimately increases its intensity
Air pollution and smoke suppress rainfall, but cause the remaining rain amounts to fall in greater intensities, with lightning and hail, says a researcher at the Hebrew University of Jerusalem. The researcher, Prof. Daniel Rosenfeld, was one of a group of scientists that included also participants... view more (2004-02-25)

New research forecasts better weather forecasts
A Purdue University researcher and his team have used improved satellite imaging and powerful computer modeling to more accurately forecast the likelihood and intensity of storms and tornados.   view more (2006-03-01)

Cities incite thunderstorms, researchers find
Summer thunderstorms become much more fierce when they collide with a city than they would otherwise be in the open countryside, according to research led by Princeton engineers.   view more (2007-08-10)

Uncovering the mechanisms of lightning varieties
The mechanism behind different types of lightning may now be understood, thanks to a combination of direct observation and computer modeling reported by a team of researchers from New Mexico Tech and Penn State.   view more (2008-03-31)

NASA's Advanced Technology Peers Deep Inside Hurricanes
Determined to understand why some storms grow into hurricanes while others fizzle, NASA scientists recently looked deep into thunderstorms off the African coast using satellites and airplanes.   view more (2007-03-07)

Clearest video of lightning-generated 'sprites' high above thunderstorms captured
Researchers at Duke University's Pratt School of Engineering have captured the best images ever produced of "sprites" - mysterious flashes of light resembling giant undulating jellyfish that can occur above strong thunderstorms - using a high-speed camera that recorded thousands of video... view more (2006-02-16)

Flying into the eye of the storm
While most of us watched this summer's violent and destructive storms on TV from the comfort of our sofas, a team of researchers from across the UK, including University of Leeds scientists Alan Blyth, Barbara Brooks and Lindsay Bennett, took to the skies in specially equipped planes to study their... view more (2004-09-29)

Research forecasts increased chances for stormy weather
Researchers who study severe weather and climate change joined forces to study the effects of global warming on the number of severe storms in the future and discovered a dramatic increase in potential storm conditions for some parts of the United States.   view more (2007-12-05)

Dogs that bite children have often not bitten kids before
Dogs that bite children have often not bitten kids before, but they tend to have underlying behavioural or medical problems, indicates research in the journal Injury Prevention.   view more (2007-10-03)

A nursery for hurricanes
Every hurricane season, about 100 low-pressure weather disturbances whirl westward out of West Africa and over the Atlantic Ocean, but less than one-fifth of them become tropical depressions, storms or hurricanes.   view more (2006-08-10)

Laughing Gas in a Vicious Circle
Italian researchers discover another mechanism for the formation of atmospheric N2O Summer smog, the ozone hole, the greenhouse effect – the complex web of chemical reactions in the atmosphere, which leads to manifold environmental problems, is still not fully cleared up. In a tricky way, a... view more (2001-05-15)

"For they sow the WIND..."
Early summer is the season for extreme weather conditions such as violent thunderstorms in central Europe. Studies undertaken by insurance companies indicate that climate change has a dramatic impact on weather conditions. No wonder, then, that home owners, farmers, gardeners and mountain climbers... view more (2002-07-22)

NCAR climate expert: Hurricanes to intensify as Earth warms
Warmer oceans, more moisture in the atmosphere, and other factors suggest that human-induced climate change will increase hurricane intensity and rainfall, according to climate expert Kevin Trenberth of the National Center for Atmospheric Research.   view more (2005-06-16)

The power of two: Envisat demonstrates combined imagery from dual sensors
The simultaneous observation of the Italian coast by two instruments onboard the European Space Agency's Envisat satellite provides a striking illustration of the unique potential of combining sensor data for a better understanding of complex Earth processes. Envisat's Advanced Synthetic Aperture... view more (2002-11-04)

Scientists accurately simulate appearance of sun's corona during eclipse
The most true-to-life computer simulation ever made of our sun's multimillion-degree outer atmosphere, the corona, successfully predicted its actual appearance during the March 29, 2006, solar eclipse, scientists have announced.   view more (2006-06-27)

NASA sees into the eye of a monster storm on Saturn
NASA's Cassini spacecraft has seen something never before seen on another planet - a hurricane-like storm at Saturn's south pole with a well-developed eye, ringed by towering clouds.   view more (2006-11-10)

NASA & NSF create unprecedented view of upper atmosphere
Scientists from NASA and the National Science Foundation discovered a way to combine ground and space observations to create an unprecedented view of upper atmosphere disturbances during space storms.   view more (2005-12-06)

Scientists close in on source of X-rays in lightning
University of Florida and Florida Institute of Technology engineering researchers have narrowed the search for the source of X-rays emitted by lightning, a feat that could one day help predict where lightning will strike.   view more (2008-07-16)

Weather Forecast Accuracy Gets Boost with New Computer Model
An advanced forecasting model that predicts several types of extreme weather with substantially improved accuracy has been adopted for day-to-day operational use by civilian and military weather forecasters.   view more (2006-08-28)

Laser triggers electrical activity in thunderstorm for the first time
A team of European scientists has deliberately triggered electrical activity in thunderclouds for the first time, according to a new paper in the latest issue of Optics Express, the Optical Society's (OSA) open-access journal. They did this by aiming high-power pulses of laser light into a... view more (2008-04-14)
