[Marvel]How do Weather Manipulators not cause lasting weather issues?

I'm drawing from a lot of different references, one point is taken from David Eddings in his Belgariad and Mallorean series. In it, the main character summons a thunderstorm, and this simple innocuous act causes huge weather issues for the rest of the world, all because he use his powers to manipulate the weather and caused a huge butterfly effect that set off blizzards where blizzards shouldn't be, and droughts. 

How do Storm and Thor not cause similar issues? We've seen that the manipulations happen pretty much at the speed of thought, ie MCU Thor turning off the rain around him and Jane, Storm making fog banks, tornadoes, etc but there doesn't seem to have any lasting issues that these new and sudden high and low pressure effects coming out of no where. 

The simplest answer I can come up with is that their power is so great that they accounting for and tweaking weather patterns around the world to compensate for the changes they are making. My co-worker, is thinking more with portals, like how Nightcrawler travels through another dimension in his teleportation, but I think he's looking at that with a D&D perspective since there are planes of existence that are specifically about those energies and elements.

The butterfly effect is really more a figure of speech, a thought experiment. The reality is that weather systems are quite stable. A localized disruption generally doesn't spiral out of control. Think of it this way - a single nuclear explosion pumps a lot of energy into the atmosphere, but the effect stays local.
