Took a 700 level course in turbulent flow. Discussed this in depth that there were projects trying to do this exact thing. None of them panned out due to the complexity of it all. Our current weather prediction super computers use 50-70k equations solved simultaneously in able to predict the weather and accuracy still doesn't go past 5 days due to uncertainty, lack of data points, and the propagation of errors.

 

The theory is though that there are critical points that can be acted upon where the least amount of input has the most drastic change in output. These can be mathematically proven in theory when you are looking at a simplified system but scaling up to actual earth weather has proven to be impossible. We had to do a thought experiment homework problem showing that if there were sensors surrounding the earth in a 1 foot by 1 foot cubic grid from the ground to space that uncertainty and propagation of errors would not allow accurate predictions anything past something like a week if I remember correctly. For human controlled climate, you'd need to know when and where these critical points occur and then be able to apply force or energy in the correct way to get the specific outcome you want. We still have trouble intercepting missiles and that is child's play compared to this shit.

We did not take into account future computational abilities or current, secret government systems. I seemed to think that no matter what improvements were made, we would never be able to fully predict what will happen and we enter the land of diminishing returns. We spent a fair amount of time studying the motion of a waterwheel that had 3 equally spaced buckets and the water dripping from directly in the center so that the waterwheel was almost constantly changing direction of rotation and the accelerations associated with it. That experiment was done in the time of punch-card computers but models were not able to predict anything past a few direction changes. After that one, I wrote off weather prediction/control being plausible but there does exist the possibility of it.

 

FWIW A long time ago I dated a crazy bitch who had a certified autist cousin working for the govt in Quantico or Annapolis maybe (can't remember). His words were that the govt is 40 years ahead of the civilian market. Couldn't get anything more out of him.
