The Adversary stated of Ororo's powers that her winds can move planets and the lightning she hurled at him, he stated were strong enough to shatter planets to dust.

1) The Mother Storm is a living tempest, therefore, it is composed of forces that fall within the purview of Ororo's powers. So, what she did to Hydroman would apply if it can be proven that Ororo is strong enough to overpower the Mother Storm (which I believe has been proven in canon). More, Stardust is a being composed of cosmic energy and look at how Storm was able to pull electrons from her and hurl them back with enough force to shatter her. In other words, even if the Mother Storm were composed of cosmic energy, Storm would still be able to wield power over it.
2) The Trion feat does prove she can access enough power to overwhelm the Mother Storm. Those feats you mentioned about the Mother Storm, "blowing comets off course, winds that can snuff out stars and yank planets out of their orbits, etc" pales in comparison to the Trion as does Odin. None of the feats you mentioned with Odin puts him at a level where he is the sum of all matter, life, and energy for an entire reality's past, present, and future. Again, the Trion were the sum of all matter/life/energy for an entire reality's past/present/future. That within itself puts them on a whole other level from either Odin or the Mother Storm. In fact, the Trion dwarfs them. The Mother Storm is only powerful on a galactic scale at best.
3) While Ororo was in a different environment when she fought the Trion, that has no bearing on the point I am making. The fact is, the Trion were controlling the same energies Storm commanded and she was able to wield those forces at a level greater than theirs. Her natural power levels were not enhanced in that dimension as the only thing that changed were the forces she commanded. If she can wield the forces of the Trion dimension at a greater level than the Trion, then she can wield the natural forces of her dimension on a scale MUCH greater than the Mother Storm, thus she can overpower it and do to it like she did to Hydroman and Stardust.
4) While you have proof of Ororo struggling to control a storm that was alive, it was hardly her best showing. The issue stated she had problems with the storms because they were sentient. She has controlled sentient beings made up of forces she commands without any problem in other stories. Again, I am taking her at her very best showings in this discussion. When taken at those levels, she trumps the Mother Storm (she's actually quite a bit more powerful than Odin as well, but until we see her apply her high end powers in ways to counter Odin's attacks, she loses to him. That said, her powerset could easily be written to counter and overwhelm Odin given its the ability to perceive the universe as patterns of energy that she can bend to her will...)
5) We may have to agree to disagree on this, but I just want to put my thoughts out there for everyone to read.
