Is above mt pay grade. Have no idea of the "why" other than speculation.

I can also attest that there has been consistent chemtrails in Outback Australia stretching many hundreds of kilometers every few days (multiple passes every few days). Previously before protesting events, I would notice only a few chemtrails every few months. Each time the chemtrails passes over my area (literally very far away from cities and towns) there is triggered monsoon low that is induced approx 100Km from my location. I am literally in Outback Australia, nowhere near any airport or passenger airline flight path. So, anytime any airplane activity is in my area, it is always gets my attention due to being rare.

I speculate the presumed manmade weather systems down in Antartica area is likely related to inducing global food shortage. Could also be to either fabricate evidence of global warming, trying to artificially terraform the area, or is part of a multizone weather system (the entire southern hemisphere is a shared weather system as is the northern hemisphere). So, maybe the latter is necessary to induce to bring results that is recommended by weather model.

Regardless, the massive storm systems we had in Australia decimated sowed seeds again (wheat, soy and barley). Has also further delayed sowing more seeds due to excessive floods, which will dramatically reduce expexted harvested yield (forecast is a minimum 25% reduction of previous harvest yield). Few more farmers had spoken out declaring they are on a knife edge, if it happens again they are forced to quit due.
