Feb 5-13 Weather Conditions

The prediction for Weather Conditions during the period of Feb 5-13th didn't age well.

Dictionary

The dictionary says this for contrails: a trail of condensed water from an aircraft or rocket at high altitude, seen as a white streak against the sky.
The dictionary says this for chemtrails: a visible trail left in the sky by an aircraft and believed by some to consist of chemical or biological agents released as part of a covert operation.

Chemtrails

Chemtrails are a conspiracy theory made up by tinfoil hat wearing plebs. The same people who believe in ' crisis actors ' and lizard people.

Contrails myth proof…

Watch the wings of any race car in cold weather, especially with Indy cars or big wing sprint cars. You can see a vapor trail coming off the wings (or spoilers) when cold air is compressed against the wing panels as the race car enters a turn. In dragsters the vapor trail is due to the extreme angle of the wing in relation to the impact of the air at which point it heats up. Once this warmed air mixes with the colder & less dense air a vapor is created.

correction

Vapor trails are the opposite. Wings and plates cause the air moving across them to accelerate, with causes a drop in static pressure and corresponding DROP in temperature. Moisture in the air moving across those fins /wings/plates then condenses into visible "vapor trails" (fog). Acceleration is highest at the edges and corners. It is most likely to be seen when the outside air temperature is warm, not cold because warm air holds more water vapor that can condenses to fog when cooled -- Aeronatical engineer

Contrails.

It all comes down to you folks. Don’t like contrails don’t fly. Don’t like global warming don’t drive,don’t heat your house,don’t use any electricity at all, don’t buy anything that has to be delivered. You think that won’t cause livability problems? It’s in everyone’s hands. Cold turkey or keep to yourself.

Exactly!! Thank you

Exactly!! Thank you

Contrails and Chemtrails are

Contrails and Chemtrails are very different things. Contrails disappear immediately. Chemtrails leave a section that expands and later blankets the sky and also have nasty chemicals for the public's unknowing inhalation. Part of trans-humanism. But that gets a bit further down the rabbit hole.

Ridiculous. You shouldn't

Ridiculous. You shouldn't have slept through science class in middle school

Very different.

So different one is rea and the other is an imaginary conspiracy morons make up.. contrails are in your head and don't exist..
