Contrail Formation, Perseverance and Spread, SCIENTIFIC SUMMARY

Contrails are a world wide occurence. These have been very well observed and reported on. There is certainly NO conspiracy involving any goverment or drug company.

Jet streams play a major part in Contrail formation, persistence and spread. See
Jet stream
From Wikipedia, the free encyclopedia
Jet streams flow from west to east in the upper portion of the troposphere.
Jet streams are fast flowing, narrow air currents found in the atmospheres of some planets. The main jet streams are located near the tropopause, the transition between the troposphere (where temperature decreases with height) and the stratosphere (where temperature increases with height).[1] The major jet streams on earth are westerly winds (flowing west to east). Their paths typically have a meandering shape; jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including the opposite direction of most of the jet. The strongest jet streams are the polar jets, at around 712 km (23,00039,000 ft) above sea level, and the higher and somewhat weaker subtropical jets at around 1016 km (33,00052,000 ft). The northern hemisphere and the southern hemisphere each have both a polar jet and a subtropical jet. The northern hemisphere polar jet is situated over the middle to northern latitudes of North America, Europe, and Asia, while the southern hemisphere polar jet mostly circles Antarctica all year round.

Predicting Contrails Using an Appleman Chart [Student]

Background: Military planners have been interested in condensation trail (contrail) forecasts since World War II. Contrails can make any aircraft easy to locate by enemy forces, and no amount of modern stealth technology can hide an aircraft if it leaves a persistent contrail in its wake. In 1953, a scientist named H. Appleman published a chart that can be used to determine when a jet airplane would or would not produce a contrail. For many years, the US Air Force Global Weather Center used a similar chart to make contrail forecasts.
Q13:What percentage of correct forecasts did you get at your school?

The US Air Force conducted studies to test the accuracy of the Appleman chart. Military pilots sometimes remark in their flight reports whether or not contrails form during their flights. Using these reports and observations of temperature, pressure and relative humidity, the USAF found that the forecasts using the Appleman method were correct about 60 to 80 percent of the time. Looking more closely at the data, they found that when no contrails were forecast, the forecast was correct 98 percent of the time! However, when contrails were forecast to occur, the forecast was correct only 25 to 35 percent of the time, and often failed to predict the occurrence of contrails. Thus, the Appleman chart tends to underpredict the occurrence of contrails and to overpredict the non-occurrence of contrails. For this reason, the USAF is actively investigating better ways to compute contrail formation.

what does this prove? except not much about anything but contrails?

@Dawgside

As Chemtrails are but a fiction, that is all it needs to prove!

Jet stream

From Wikipedia, the free encyclopedia

Jet streams and Aviation

Flights between Tokyo and Los Angeles using the jet stream eastbound and a great circle route westbound.

The location of the jet stream is extremely important for aviation. Commercial use of the jet stream began on November 18, 1952, when Pan Am flew from Tokyo to Honolulu at an altitude of 7,600 metres (25,000 ft). It cut the trip time by over one-third, from 18 to 11.5 hours.[22]

[ERNIEMAC2]

Not only does it cut time off the flight, it also nets fuel savings for the airline industry.[23] Within North America, the time needed to fly east across the continent can be decreased by about 30 minutes if an airplane can fly with the jet stream, or increased by more than that amount if it must fly west against it.

@ERNIEMAC2 LOL who's paying you to come up with this garbage?

[jezzyby47]

@ERNIEMAC2 - ARE YOU SERIOUS erniemac2?

Chemtrails are but a fiction?

Your video says that contrails cover 0.1% of the earths surface, so what about the rest?

What about the clouds that have had Very high levels of Aluminium and Barium found in them, amounts that are toxic to humans by over 1000 times?

I seriously hope that the amount of blood money you are getting paid to put this rubbish out sits OK with your conscience because you are in effect saying that black is white.

@Terrorizer321 You have to forgive Ernie as he knows not what he does.

"We are all born ignorant, but one must work hard to remain stupid." Everytime I see this sentence, I think of poor deranged Ernie.

must be all wrong ?

ALL of the meteorologists and space scientists there are all DILLS ?

[timeaification]

It's DOUBLETHINK

[timeaification]

Yes yes thats it man jezzyby47. Black is white, lol that is amazing. Like saying the sky is red like some really believing, if nasa and shit say it is so it is so. The sky is red because lol. I have been trying to come up with a way of saying exactly that. It's a case of perception or what reality you want to live in, it doesn't matter what evidence we have, ''the truth is not determined by the evidence that suppoerts it'' ''rather by the official story''.

@jezzyby47

What aluminum salt was involved ? Was it pure or was it in with other waste?

[jezzyby47]

@jezzyby47 - Yes there are contrails, but they only occur in high humidity places according to your own video, so we must all have severe daily thunderstorms in that case, yet surprisingly we don't.

If you need proof that Aluminium is poisonous check out todays news when a lorry load of it got poured into the water in Cornwall and a woman died as a result of these high levels of it in her system.

@SassyWolfKitten If a person has a Wikipedia account then can change the information. That's true because I know somebody who did it just to see if it would work.

[SassyWolfKitten]

That stupid music sounds like what my 8th grade teacher Mrs. Cheswick made us listen to when we were trying to take tests. I just wadded up kleenex and stuck it in my ears to mute it. It didn't work very well but it helped a little. At least on here we can turn the volume off. which btw I did.

[SassyWolfKitten]

@Riiccko LOLOLOLOL I just told him that same thing then I saw you said it too. For all we know he's the one that wrote the Wiki article since anybody can submit them. LOLOLOLOL
