NASA researchers have begun a series of flights using the agency's DC-8 flying laboratory to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude. The Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS) research involves flying the DC-8 as high as 40,000 feet while an instrumented NASA Falcon HU-25 aircraft trails behind at distances ranging from 300 feet to more than 10 miles. "We believe this study will...

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...

Meteorologists launched a new campaign Wednesday to get people in England involved in measuring climate change by using a mirror, soap bubbles or by looking up at the sky. The Met Office national weather service is asking people to complete a series of simple activities to check the results of climatic computer models. The activities include measuring wind speed by blowing bubbles into the air, to monitoring the direction of clouds with the aid of a mirror as methods to measure climate...

By Michael Finneran, NASA Langley Research Center When Patrick Minnis saw video of the "mystery" contrail Nov. 9 that looked like a missile launch near Catalina Island off Los Angeles, he figured it the way most people did. "I assumed it was a missile," said Minnis, a contrail expert in the Science Directorate at NASA's Langley Research Center in Hampton, Va. Then he got a call from an Associated Press reporter and told her, yes, it sure looks like a missile. "She responded with links to two...

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...

Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of heavy ice crystals that precipitate from them. This precipitation often indicates the difference in...
