Perhaps you have not been reading the entire thread? The multiple responses here, and in many other so-called "chemtrail" threads either?
I think it's a bit odd that they're predicting severe storms for this evening and they're checkerboarding us this morning. Hmmm . .
You say there are forecasts for approaching weather, and storms? Well, the existence of the contrails that precede
change in weather is for the EXACT same reason that other high-altitude cirrus clouds will sometimes also do the same thing....and this happens in
Nature everywhere, whether an airplane flies by or not.
How to Forecast the Weather Using Clouds
Cirrus clouds are the most abundant of all high level clouds. They are made out of ice and are thin, wispy clouds blown in high winds and gusts
into long streamers. These feathery clouds usually spread across the sky. Streaming cirrus clouds are also called mare's tails. Although single or
maybe a few cirrus clouds can indicate that there is fair weather coming, a gradually increasing cover of cirrus clouds may show that an approaching
warm front is coming. By observing the movement of cirrus clouds you can tell from which direction the weather is coming. When you see cirrus
clouds, it usually indicates that a change in the weather will occur within 24 hours.
You can do your own searches online, to find many other sites that explain the concept of clouds, and weather, and weather changes.
Mariners have been using clouds, and sky changes, to predict weather for thousands of years......
Contrails that are formed, and seem to be a "grid" are simple to understand, also. Let's pick a place in Oklahoma for an illustration --- what
about Oklahoma City?:
Here is the High Altitude Aeronautical Chart for your area,
centered on Oklahoma City
This is used by all flights above 18,000 feet...up to a maximum of 60,000. Commercial air traffic is usually from 30,000 to 41,000 feet.
The heavy black lines show all of the established Jet Airways that are used for routing flights.....however, airplanes can fly on any heading and any
direction, as needed during any typical day of operation.
Look at how they cross each other, in various patterns and at various angles. Just centering on Will Rogers VOR (IRW) at the Oklahoma City Airport,
you see that any flights navigating overhead that spot can be north/south and east/west, and at nearly 90° angles.
Now....the airplanes navigate by reference to the ground, of course. SO each flight that remains on, and follows a Jet Airway, will travel over the
ground in the same manner. BUT, clouds drift with the winds....carried along, and move over the ground, in the direction the wind happens to be
blowing. So, one airplane flies north, leaves a contrail...that trail drifts with the winds, let's say the winds ids from the NorthWest
Ten minutes later, an airplane on the exact same course, that is following behind the first one, flies along and leaves another contrail. Now, you
have two contrails, parallel to each other, but separate by those ten minutes that elapsed, and the first one has moved with the wind.
Repeat that process, and add in flights travelling east/west.
You now have a "grid". This only shows up, this pattern, when the contrails happen to be in conditions that allow them to linger and
persist....just like the CIRRUS clouds that may be there also. (Read up about cirrus clouds, and weather changes that may be approaching).
