Scientists have identified several elements in the lunar atmosphere, including oxygen, silicon, and aluminum, but only in small amounts. The study aims to learn which other atoms the regolith may release and form part of the Moon's atmosphere.
Researchers at Penn State used global and regional climate models to investigate climate change differences. They found that regional models produced warmer temperatures, leading to more rain and less snowfall in the Northeastern United States.
A computer model developed by Penn State researchers can predict the probability of land use change and microclimate formation in urban areas. The model uses satellite image data to calculate land use types, vegetation, and surface climate parameters, providing insights into urban growth and its impact on local liveability.
A team of scientists is tracking El Niño changes using a remote cloud observatory in the Western Pacific. Continuous measurements are being collected to evaluate and develop cloud property and radiation algorithms for global climate models.
The AAAS awards recognize individuals who have made significant contributions to science, including Peter H. Raven for his service to ecology and sustainability, and Bert Richard Johannes Bolin for his leadership in international research programs on climate change. The winners of the 1997-1998 AAAS Science Journalism Awards will be an...
A new study analyzes US hurricane damage data, normalizing for inflation, coastal population increase, and wealth. It finds that landfalling hurricanes in the 1940s-1960s would have produced over $10 billion in damages if they struck today, contradicting claims of climate change causing recent damage increases.
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.
The study enhances lightning detection capabilities with total lightning measurements, providing more accurate forecasts of severe storms and storm morphology. This technology has the potential to improve space launch weather support and reduce delays or scrubs due to adverse weather conditions.
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.
The prototype non-Doppler optical sensor registers faint wind movements that anemometers cannot measure, correlating with those of anemometers in test results. It offers a low-cost alternative to complex arrays of traditional sensors and can measure both horizontal and vertical wind speeds.
The monsoon's peculiar ocean currents increase nutrients, boosting plankton productivity. This boost converts carbon dioxide to organic forms, storing it in deeper layers and reducing atmospheric CO2 levels.
Researchers are conducting studies on wind load, wind engineering meteorology, and wind flow around low-rise buildings. Computer programs have been developed to calculate direct/indirect costs of natural hazard disasters. The goal is to mitigate damage caused by hurricanes and other severe weather events.
The NCAR research program is testing a new cloud-seeding technique using pyrotechnic flares to enhance rainfall in drought-stricken Coahuila, Mexico. The technique has shown promising results in South Africa and Arizona, but its effectiveness remains uncertain.
