No Science, Pure Miracle
The fictional scenario in this film defies nearly every law of physics taught in high school. It disregards the laws of Conservation of Energy, Conservation of Momentum, and principles of Thermodynamics by suggesting that small-scale interventions like chemicals and cloud seeding could dissipate a tornado. In reality, the energy and momentum driving a tornado are far too immense to be neutralized or redirected by such means.
So, if it’s not science, what is it about? As the cowboy hat puts it, "It's part science, part religion."
I'd say "it's no science, pure miracle."
