Airplanes Cause Accidental Cloud Seeding

An anonymous reader writes "A new study by a team of U.S. researchers found that commercial and private jetliners may be contributing to a form of accidental cloud seeding. When an airplane flies through a cloud, its propellers cause the expansion and cooling of the air behind them which can cause water droplets to spontaneously cool and crystals to form. The aircraft sets off a chain reaction in the cloud that can continue on for hours after the plane has passed by. The researchers also discovered that this phenomenon is more common near the poles, where many of Earth's weather monitoring systems are, and it could be skewing data that research teams are gathering in those areas."

    Meteorologists have known about this for some time. They tend to form what is known as "Hole Punch" clouds.

  2. How is this news by Anonymous Coward · · Score: 5, Informative

    I mean seriously, this has been known for decades. There was even a study that looked at the 9-11 shutdown of air-traffic affected climate.

    This has been known for a long time.

    "commercial and private jetliners" "When an airplane flies through a cloud, its propellers"

    The number of jetliners with "propellers" is mighty fucking few, though not zero.

    Linking to the PARENT Science Daily piece

    instead of the pointless Inhabitat bullshit summary would have been nice. There is NO excuse for the Inhabitat link other than SPAM.

    AC is anonymous because he/she/it wants page hits for Inhabitat.
    Now I know not to visit Inhabitat again. Fuck you too and thanks for nothing.
