This contradicts the "experts" claims that contrails are more prevalent this time of year. They claim that contrails are less visible during the summer due to atmospheric conditions and they increase during the fall and winter. Well, call me captain obvious but chemtrails are visible year round. They are everywhere all the time no matter the weather. The season has nothing o do with it.
I'm tired of the ATS experts who contradict themselves with untruthful statements that are claimed to be fact in the name of science.
You know this for a FACT...
.... or this is a THEORY....
Because you seem to speak with such authority one would infer you know what is causing them...
....with new contrail forecasting algorithms for three aircraft engine categories- non-bypass turbojet, low-bypass turbofan, and high bypass turbofan....
An engine performing with a higher overall propulsion efficiency causes plume conditions which during mixing reach a higher relative humidity for the same ambient temperature, thus causing contrails also at a higher ambient temperature.
THE HIGH BYPASS TURBOFAN
The first generation of jet engines were used from the 1950s to the 1980s. The current generation began appearing in the early ‘80s and the conversion to them was completed by 1995 or earlier. The first generation jet engines had the appearance of a short cigar with the inlet nozzle and the outlet exhaust nozzles about the same size, about 3 feet in diameter. The new next generation jet looks a bit like a side-ways funnel, with the front nozzle opening about 6 times larger than the exhaust in the back, with a tapered cowling running from the large opening in front to the small one in the back. Inside that cowling, at the front, is the "High Bypass Turbofan." It is like a turbocharger add-on for a car. It pumps in extra air into the jet engine. But most of the air flows around and past the engine, between the engine and the cowling. This maintains a constant sea-level air pressure on the engine – during high thrust takeoff and in the extremely thin air at normal cruise level.
The new generation engines never "starve" for air and thus never dump half-unburned smoky fuel out the back. This increases the efficiency of the engine, produces more power and eliminates all the sooty oily black exhaust. You may remember that in the 1970s there were debates and articles about the problem of the unburned and partially burned hydrocarbons jets were spewing into the atmosphere – and in the 1980s those debates went away – because the unburned and partially burned hydrocarbons went away, thanks to the High Bypass Turbofan.
The primary outcomes of the invention of High Bypass Turbofan was to increase the efficiency of the jet engine – which it did by a huge amount – and to produce persistent contrails, now called "chemtrails." First generation jet engines were less than 20% efficient, and the High Bypass Turbofan made them more than 90% efficient! This means it took significantly less fuel to fly an airliner equipped with the High Bypass Turbofan from point A to B, thus a huge increase in profit for the airlines.
By the mid-1990s all old jets had been upgraded to the new engine configuration and all new planes coming off the assembly line were equipped with the most modern versions. But this new next generation of jet engines had one curious "side effect." They produced contrails that can persist for more than 24 to 36 hours! Condensation trails from first generation jet engines generally only lasted for about 10 or 20 minutes and then they disappeared. But these new "chemtrails" persist all day long – and with 35,000 commercial flights in the US air lanes each day, these new persistent contrails produce numerous crisscrossing, tic-tac-toe patterns all over the sky. So, why do the new contrails now last all day long?
"Chemtrails" is a popular misconception that actually plays into the hands of the military, as all this Chicken Little nonsense has kept the mainstream media from investigating and reporting on the real releases and the real environmental dangers. Sadly, "chemtrail" activists are doing more harm than good. Rather than agitating against "chemtrails" we should be advocating "blue skies." Unfortunately, that might ground the aircraft industry as we know it.
I hate the Chemtrail threads

Good video and interesting. However, I did notice that the contrails in the video widen out as the wind blows them over time. The ones I saw were ALL fairly skinny sized at the same point in time i.e. one was not wider than the other in a sequence. There were approximately 20-25 of these laid across the sky in about 10 degreee increments from the eastern horizon to the western horizion. I'm certainly open to hearing a solid theory on how that effect can occur in the normal course of airline travel (over Portland). Portland, OR isn't exactly a giant metropolis where jets pack the skys from east to west. The prevalent landing and takeoff patterns (runways) at PDX are in the opposite direction.

Yep. For the first time last week I saw what looked to me to be chemtrails in the sky over Vancouver, Washington. There was no airshow in the area and I took these photos from my iPhone as I was leaving work. I was looking eastward but these covered the entire sky. It was erie.
