Even though the article says that it's designed to see how winds move in space, we all know there's no wind in space, so, of course, they're talking about the upper atmosphere you're speaking about.
The solar wind is responsible for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field strongly affect Earth's local space environment. For example, the levels of ionizing radiation and radio interference can vary by factors of hundreds to thousands; and the shape and location of the magnetopause and bow shock wave upstream of it can change by several Earth radii, exposing geosynchronous satellites to the direct solar wind. These phenomena are collectively called space weather.
The two jet streams, polar and subtropical, are bands of strong wind in the upper atmosphere. Winds within the jet stream flow from west to east or north to south along boundaries of hot and cold air. Several factors influence the jet stream, such as the Earth's rotation, air temperatures, high and low pressure systems, seasonal changes and solar flares. Solar flares disturb Earth's atmosphere, thus modifying weather patterns.
Solar flares are sudden, violent eruptions on the sun's surface. Energy released from solar flares can be equivalent to millions of hydrogen bombs. During a flare, heated protons and electrons eject into space, creating weather changes on Earth. Due to the distance between the sun and Earth, effects felt on Earth do not occur until several days after the flare.
So, if this experiement was addressing solar wind and how it affects the jet stream...
Times have changed and the military has extensively utilized Space assets in operations for approximately the last twenty years. Thus for two solar cycles, specifically cycles 22 and 23, we have incorporated Space weather into mission analysis. Weather in general has had significant impact on operations since warfare began; either benefiting one force or the other. The following are just a few examples of such operational impacts created by weather conditions. In 1915, German forces use of poison gas and wind blew the chemicals back onto German lines and destroyed four Prussian regiments. In 1944, the D-Day weather forecast was for conditions favorable to air, sea and ground operations together ? a rare event.

I won't argue that aspect. Radio and satellite communications are huge parts of the system that the Military Industrial Complex relies upon in order to succeed.
I just don't understand why the experiments can't be telling them this info as well as providing info about how chemicals can be carried by the jet stream.
which can't carry chemicals in any useful manner.

Well, I guess all those reports of the chemical trail sightings from multiple states were all lies.
If the jet stream cannot carry the trails, why would they have anticipated viewing the trails over NC and NJ?
Earth's Two Jet Streams
High in the sky, 60 to 65 miles above Earth's surface, winds rush through a little understood region of Earth's atmosphere at speeds of 200 to 300 miles per hour.
First noticed in the 1960s, the winds in this jet stream shouldn't be confused with the lower jet stream located around 30,000 feet, through which passenger jets fly and which is reported in weather forecasts. These 2 jet streams are vertically 50 miles apart.
In March 2012, NASA will launch five rockets in approximately five minutes to study these high-altitude winds and their intimate connection to the complicated electrical current patterns that surround Earth. Credit: NASA/Goddard Space Flight Center
So again, how were people on the ground able to see the trails from several different states if the trails were 50 miles ABOVE the jet stream that's 30,000 feet above our heads?
Also, you stated that the jet stream in question cannot carry/push chemicals, so how did the trails get over NJ?
Sure, this thread is in the geoengineering forum, but I will not rule out that this experiment can also give them answers and information that may be pertinent to how chemicals can be used during warfare.

For the last time, I'm not commenting about JUST the weather. I asked you a specific question about that jet stream and you avoided the question.

We present the first thermospheric wind measurements using a Doppler Asymmetric Spatial Heterodyne (DASH) spectrometer and the oxygen red-line nightglow emission. The ground-based observations were made from Washington, DC and include simultaneous calibration measurements to track and correct instrument drifts.
The wind data are commensurate with a representative set of Millstone Hill Fabry-Perot wind measurements selected for similar geomagnetic and solar cycle conditions.
In atmospheric and space environment studies it is key to understand and to quantify the coupling of atmospheric regions and the solar impacts on the whole atmosphere system. There is thus a need for a numerical model that encompasses the whole atmosphere and can self consistently simulate the dynamic, physical, chemical, radiative, and electrodynamic processes that are important for the Sun Earth system.
This is the goal for developing the National Center for Atmospheric Research (NCAR) Whole Atmosphere Community Climate Model (WACCM). In this work, we report the development and preliminary validation of the thermospheric extension of WACCM (WACCM X), which extends from the Earth s surface to the upper thermosphere.
We evaluate the model performance by examining the quantities essential for the climate and weather of the upper atmosphere: the mean compositional, thermal, and wind structures from the troposphere to the upper thermosphere and their variability on interannual, seasonal, and daily scales. These quantities are compared with observational and previous model results.
