This is known as a distrail (short for "dissipation trail"). The plane's warm engine exhaust and enhanced vertical mixing in the aircraft's wake can cause existing cloud droplets to evaporate. If the cloud is sufficiently thin, such processes can yield a cloud-free corridor in an otherwise solid cloud layer. [47]
Operation Popeye / Sober Popeye (Project Controlled Weather Popeye / Motorpool / Intermediary-Compatriot) was a military cloud-seeding project carried out by the U.S. Air Force during the Vietnam War in 1967–1972.
An Airbus A340's engines leaving a water condensation trail – miniature clouds formed by the engine exhaust. The chemtrail conspiracy theory / ˈ k ɛ m t r eɪ l / is the erroneous [1] belief that long-lasting condensation trails left in the sky by high-flying aircraft are actually "chemtrails" consisting of chemical or biological agents, sprayed for nefarious purposes undisclosed to the ...
More and more water accumulates on the seed until a visible cloud is formed. In the case of ship tracks, the cloud seeds are stretched over a long narrow path where the wind has blown the ship's exhaust, so the resulting clouds resemble long strings over the ocean. [2] Ship tracks are a type of homogenitus cloud. [3]
It was hoped that the increased rainfall would reduce the rate of infiltration down the trail. [ 1 ] A research paper produced for the United States Air Force written in 1996 speculates about the future use of nanotechnology to produce "artificial weather", clouds of microscopic computer particles all communicating with each other to form an ...
Storm clouds moving over the summit of Mount Washington and Tuckerman Ravine. Rescue operations began around 8:30 p.m. — and by 11 p.m., there were nine highly skilled rescuers on the summit.
The Cactus to Clouds Trail (C2C) is a hiking route in California.It begins in Palm Springs, California, and ascends to San Jacinto Peak.With a net elevation gain of roughly 10,300 feet (3,100 m), it has one of the greatest elevation increases among day-hike routes in the United States.
Aviaticus cloud Persistent condensation trails (contrails) formed by ice crystals originating from water vapor emitted by aircraft engines. Usually resembles cirrus; recognized as a WMO genitus cloud cirrus homogenitus (man-made). Further transformation into cirrus, cirrocumulus, or cirrostratus homomutatus is possible depending on atmospheric ...
