Unexpected similarities between raindrops and proteins
Raindrops and proteins seem to have a lot in common. This has been shown in a new study by scientists at Ume'å University in Sweden. The principle behind the formation of raindrops is very similar to how proteins fold. This knowledge is vital to our understanding of neurodegenerative diseases like ALS. These findings have been published in... view more... (2004-05-26)
Maybe it's raining less than we thought
It's conventional wisdom in atmospheric science circles: large raindrops fall faster than smaller drops, because they're bigger and heavier. view more (2009-06-11)
Raindrops go ballistic in research on soil erosion
Raindrops can wreak havoc on Earth. They just do it on a microscopic scale. At that scale, raindrops hitting bare ground have nearly the force of a hammer hitting a mound of dirt. view more (2007-01-19)
New instrument reveals raindrop formation in warm clouds
How do raindrops form? It's a simple question, but the answer is far from elementary. Tiny water droplets somehow merge to become full-sized raindrops, but the details remain a mystery. view more (2006-12-11)
For hurricanes, storms, raindrop size makes all the difference
When Tropical Storm Gaston hit Richmond, Va., in August 2004, its notable abundance of small and mid-sized raindrops created torrential rains that led to unexpected flash flooding throughout the city and its suburbs. New research from NASA has concluded that tropical cyclones like Gaston produce rain differently than another class of storms called... view more... (2008-06-10)
Ancient raindrops reveal the origins of California's Sierra Nevada range
One of the longest ongoing controversies in Earth science concerns the age of California's Sierra Nevada, the tallest mountain range in the continental United States and site of Yosemite National Park, Lake Tahoe and other scenic wonders. view more (2006-07-07)
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 rainfall in the western U.S. view more (2005-12-12)
Kura garnu ramro hunchha: It's good to talk
THOUSANDS of breathless trekkers each year gratefully stop to admire the stunning high altitude scenery as they pass through the village of Landruk on their way to Nepal's famous Annapurna mountain range. As their gaze shifts from the famous 'Fish Tail' mountain to the brilliant green sloping terraced foot hills 6,000 ft up the Himalayas they... view more... (2003-09-05)
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 from Germany, Sweden and Brazil who conducted... view more... (2004-02-25)
Highly sensitive weather radar a gain for climate research
TU Delft has taken a new weather radar system into use, the 'Drizzle Radar', which can observe even the lightest of drizzles. This is an enormous gain for climate researchers and is attracting international attention. view more (2007-08-27)
Forecast: Showers and thunderstorms
People planning baseball games, picnics, and other outdoor events may have more precise short-term forecasts of rainfall in the next few years, thanks to an observing strategy now being tested by atmospheric scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. view more (2006-08-02)
Science paper examines role of aerosols in climate change
A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models. view more (2008-09-08)
Pollution shown cutting rainfall in hilly areas
Manmade climate change due to pollution seriously inhibits precipitation over hills in semi-arid regions, a phenomenon with dire consequences for water resources in the Middle east and many other parts of the world. view more (2007-03-09)
NASA data link pollution to rainy summer days in the southeast
Rainfall data from a NASA satellite show that summertime storms in the southeastern United States shed more rainfall midweek than on weekends. Scientists say air pollution from humans is likely driving that trend. view more (2008-02-04)
