Chemtrail spraying screaching to a halt! Obama mandate?

Once again, an understanding of summer weather patterns + pressure gradients + RH and weather conditions all work together to create contrail or no contrail days.

These are all already considered using the correct Appleman Chart (in this case the Mid-Latitude Summer chart. Its our United States Air Force and NASA that claim the Appleman Chart to be correct 98% of the time in predicting (NO CONTRAILS). This is a necessity in planning day missions (or night missions with moonlight) in which contrails will reveal the aircraft on mission to the enemy.

So, I don't see any room for you or anyone else to "explain away" the chart being dead wrong in predicting NO CONTRAILS more than 50% of the time.

On the other hand, the Appleman Chart was devised in the early 1950s and, strange as it may seem, research into contrail formation has moved on a bit since then

See, for example,

A new formulation for the critical temperature for contrail formation

An empirical model to predict widespread occurence of contrails

That is some REALLY obscure 2 links you produced! By God! They are BOTH from 1996, 12 years ago... and OBVIOUSLY unembraced by the rest of the World, since they are almost never cited by anyone other than you (NASA and the USAF still reference Appleman). So like I said in the other thread, if you are right you should petition Nobel, cuz you must know more than the rest of science.

True. When discussing conditions for contrail research, Pat Minnis quotes the likes of Sassen and Dodd 1989, Strom et al. 2003, Gierens et al. 1999, Jensen et al. 2001 and so on.

There have been many studies since 1953. And amazing as it seems, we nowadays use mesoscale models for calculating the likelihood of contrail formation (Stuefer et al. claiming, for example, an 82% success rate using their MM5 model in Alaska )

It is however easier to explain an Appleman chart to lay people and students than to expect them to understand complex algorithms or, indeed, for them to have access to high powered computer models. Which is why his chart is still used as a basic tool.

When explaining how to look at a weather chart and determine the likelihood of snow we will mention 850hPa temperatures and thicknesses and they do give a general indication - but in reality it's a lot more complex. Sometimes temp and thicknesses need to be lower, other times heavy snow can occur with higher temps and thicknesses. Likewise with contrail formation and persistence. Temperature and RH give a rough indication - and for them we may use an Appleman chart - but the reality is much more complex.

thinking someone may be interested... I am attempting to provide a link to areosol operations and hoping it works. phoenics.chemistry.uoc.gr...

hey i live in the inland northwest and our skys have been cloudy for days... however when the clouds roll away really quickly sometimes to i have seen kc-135's which are returning to an AFB right near my house and their trails which usually strech for miles and become "cloud like" are only staying visible for like a hundred feet behind the airplane. (this was on like january 3rd.)

Question for those that believe in Chemtrails. Do you feel that the purpose is to adversely affect one's health, or do you feel that there is some sort of mind altering substance being used? What are the symptoms of inhaling these chemicals? How are those that are responsible immune from these effects?

Yes, I agree, I'm in Oregon and I noticed the day he took office that we weren't sprayed at all. We had, for once, had very clear days and barely even a contrail considering I live 100 miles south of Portland. Glad you posted this. They are running scared, plus a Northern Califorina and Southern Oregon newspaper put a full page ad about chemtrails and what it is doing to our natural resources. That was cool.

Gday Im not sure where in Oregon you're from but the latest radiosonde data, indicates a likelihood on no persistent contrails. There is far from enough moisture at crusing altitude

I haven't noticed much of a decrease where I am, sadly. It seems to be about the same. Of course I can't really tell because it's usually cloudy where I live, but on clear days it looks like the sky is getting sprayed pretty bad.

Also, from what I understand from people who've lived out where I am for a while, the winters out here have gotten pretty mild over the past 20 years or so. They used to be so bad that Lake Erie would freeze clear on over to Canada, and now it doesn't get cold enough for it to freeze at all, really. The winters are coming a bit later and ending a bit earlier from what I've heard.

I'm not sure if that has anything to do with chemtrails, but it probably does.

Haven't seen much of a decline in Louisiana.

I live in Southern Oregon. We have been sprayed heavily nearly every day for the last couple years, but it seems like they take off the weekends; they aren't as bad then. For about 5-6 days, from Presiden'ts Day, through the weekend, and through the innauguration, there was little or no spraying. I figured they were "on vacation", and that the spraying would start up after the inauguration ... sure enough, two days after the inauguration, it started ... not as heavily as before, but there are plenty of stripes up there. Today we started with a beautiful, clear blue sky, but the chemtrails created whiteness over the sky. A few hours later, it cleared up, but they were at it again, creating new stripes. During heavy spraying, people talk about their headaches and sinus problems, wondering why they have them.

Hi Stardust,

I am curious as to which Northern California newspaper printed a full page ad about chemtrails, and when? I would like to get a copy of that.

I live in Northern California, and I'm still seeing them, but I have noticed the level of spray drop slightly.

I live in Central Florida and have seen no chemtrails for 2 weeks, today they are at it again and very heavy. 2/9/09

Hi, BlueRaja.

[ No chemtrail today near Montreal, CYUL, CYHU ].

Here are some videos to pounder:

Here, the trails are not EVEN BEHIND the engines !

PRESS PAUSE AT 0:20 seconds ! ! ! !

Look top right !

Blue skies. . .I hope. . .

Today os the first time in about a month of so that i have noticed any. I can see about 70 different lines right now though.

It's funny you mention contrails are at a minimum this time of year.

This thread shows that the phenomena is possibly seasonal.

Make what you will of it.

I know this will be an amazing mind blowing fact to some people, but yes the air is colder in the winter, and warmer in the summer. Colder air is more conducive to contrails and to be longer lasting. Warmer air is less favorable for it.

Thats why every winter on chemtrail boards "Wow, biggest spray day ever", and then on those same chemtrail boards, things die off in the summer. They seem to have a problem putting 2 + 2 together

Another phenomenon is called condensation trails forming behind wings. The low pressure behind the wings causes water vapor to condense and form a cloud. It doesnt always have to form from engines.

Constantly happening where I am, no let up... in fact, seems to be a little more than it used to be.
