Contrails in a sentence

After Google does more testing (including on night flights, when contrails can have a bigger effect), it plans to make its data and tools freely available so anyone can use them.

Contrails from jets circle a suspected Chinese spy balloon as it floats off the coast in Surfside Beach, South Carolina, U.S. February 4, 2023.

Despite being smaller and burning much less fuel, the researchers found that private jets produce contrails comparable to those of larger commercial aircraft.

Despite being smaller and using less fuel, private jets create similar contrails to much larger commercial aircraft, the analysis found, which surprised the researchers.

Google also partnered with Breakthrough Energy, turning its AI models on past data in an attempt to predict conditions that would lead to more contrails.

Very likely not even Smith has any interest in contrails.

While, yes, jet engines do indeed leave contrails, those generally disappear within a couple of minutes at the most, even under the most favorable conditions (high humidity) for them lingering the longest, observers say.

If the Hummer brand can be reborn as an electric vehicle, then we expect contrails of bacon flying overhead—and, of course, a version with a pickup bed.

Other aircraft that actively attempt to avoid detection try to suppress their contrails.

There are some routine contrails (not chemtrails!) above the city from arriving flights, but no indication any of those airplanes are bringing in brigades of Antifa commandos.

Researchers from the German Aerospace Center have concluded that contrails can trap heat in the atmosphere, and could have a bigger impact on global warming than the carbon aviation produces.

Yet shills for the "official story" of "climate change" try to pass off pictures of air shows, pictures of sky writing, and pictures of normal contrails cropped so you don't see that the contrail dissipates!

Contrails, short for condensation trails, are formed from the water vapor found in aircraft exhaust as a byproduct of fuel combustion.

Contrails formed from the exhaust of aircraft flying in the high étage can persist and spread into formations resembling any of the high cloud genus-types.

Contrails produced from jet engine exhaust are seen at high altitude, directly behind each engine.

Edward I’s great gray castle rose up in the middle foreground, and the high contrails of RAF jets on a training exercise out over the Irish Sea showed that the town’s current overlords still maintained the old watch.

Exhaust contrails usually form at high altitudes; usually above convert, where the air temperature is below convert.

Iridescent contrails from a Boeing 747. This effect happens when water molecules interact with the aircraft and the sun shines through them.

Studies have found that contrails trap outgoing longwave radiation emitted by the Earth and atmosphere (positive radiative forcing) at a greater rate than they reflect incoming solar radiation (negative radiative forcing).

The ice crystals in contrails are much smaller than those in naturally-occurring cirrus cloud, as they are around 0.001 millimeters to 0.1 millimeters in length.
