Historic demonstration based on three years of research. Tampa, FL (PRWEB) February 20, 2014 One year ago today, researchers at the Insurance Institute for Business & Home Safety (IBHS) made history by creating the first-ever full-scale hailstorm in a controlled laboratory environment during a test demonstration at the IBHS Research Center in Richburg, S.C. “Replicating a hailstorm as closely as possible to what we observe in the field involved a great deal of creativity, scientific...

Lee Rannals for redOrbit.com — Your Universe Online Scientists are turning what some could think of as "evil genius science", and using it for good, by developing a way to turn down the rage of a hurricane. A team of scientists claim they have a technique that could reduce hurricane intensity by a category. The authors wrote in the journal Atmospheric Science Letters that they could use cloud seeding as a technique to decrease sea surface temperatures, where hurricanes form....

Russia Blames HAARP Transmitter For Phobos-Grunt Failure
2011-12-15 12:32:37

After abandoning efforts to save its Martian moon probe, Phobos-Grunt, that has been stranded in Earth´s orbit since early November, Russia is now focusing on where the blame lies for the expensive mishap. The accused: Alaska´s High-frequency Active Auroral Research Program (HAARP) transmitter. Phobos-Grunt, now considered a 7.5 ton heap of space debris, is expected to plunge back to Earth around January 9, two months after it became stranded, according to Russian space agency,...

Powerful Laser Could Help Make Rain One Day

  Researchers from the University of Geneva report they could soon be able to control when and where rain falls. Using a powerful laser, researchers created water droplets in the air over the Rhone River in Switzerland. Using laser-assisted water condensation, they hope it could one day unlock the secrets of weather cycles and enable humans to make their own weather systems. While ℠cloud seeding´ has existed for some time it is not considered a safe way of creating...

Researchers say that aircraft can lead to increased snowfall around the world's major airports. New research shows that numerous private and commercial flights have been drilling holes and canals though clouds, influencing the snow and rainfall below them. The inadvertent cloud-seeding effects are facilitated by the expansion and cooling of air behind a propeller aircraft's engine blades and over aircraft wings when supercooled cloud temperatures are about 14 degrees Fahrenheit and...

Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions. The new study led by the National Center for Atmospheric Research (NCAR), is part of ongoing research that focuses on so-called hole punch and canal clouds that form when planes fly through certain mid-level clouds, forcing nearby air to rapidly expand and cool. This causes water droplets to...

Airborne microorganisms may be responsible for weather events, according to a study that found a high concentration of bacteria at the center of hailstones. Alexander Michaud from Montana State University in Bozeman presented the findings of the study at the 111th General Meeting of the American Society for Microbiology in New Orleans. Researchers analyzed hailstones that measure over 5 centimeters in diameter (about 2 inches) which were collected on the University campus after a storm in...

In many areas of the world, including California's Mojave Desert, rain is a precious and rare resource. To encourage rainfall, scientists use "cloud seeding," a weather modification process designed to increase precipitation amounts by dispersing chemicals into the clouds. But research now reveals that the common practice of cloud seeding with materials such as silver iodide and frozen carbon dioxide may not be as effective as it had been hoped. In the most comprehensive reassessment of the...

As turboprop and jet aircraft climb or descend under certain atmospheric conditions, they can inadvertently seed mid-level clouds and cause narrow bands of snow or rain to develop and fall to the ground, new research finds. Through this seeding process, they leave behind odd-shaped holes or channels in the clouds, which have long fascinated the public. The key ingredient for developing these holes in the clouds: water droplets at subfreezing temperatures, below about 5 degrees Fahrenheit (-15...

In an effort to alleviate the effects of a severe drought, Cuba had provided Venezuela with cloud seeding help. Hugo Chavez said Fidel Castro and Cuban president Raul Castro sent specialized equipment to the people of Venezuela to be used to seed clouds from planes. Chavez says, "We're bombarding clouds. We have some planes there, and some equipment that Fidel and Raul sent us." As his country heads into its dry season, Chavez is trying to squeeze more rain from the clouds. Reservoirs are at...
