Thor: 10 Legendary Mjolnir Facts
8. Weather Manipulation
The uninitiated think that all Mjolnir is good for is throwing lighting, causing the crash of thunder, and making it rain, but the item's powers of weather manipulation are so much more vast and nuanced than that. Thor can actually control the weather without the hammer, but Mjolnir allows him to exert greater control over the base elements of the storm.
Anyone worthy of wielding Mjolnir can create huge, violent electrical storms with hurricane-force winds, torrential rain, thunder, lightning, devastating tornadoes, blizzards, tidal waves. whirlpools, and earthquakes at the speed of thought. Those users of Mjolnir can also stop the phenomena almost immediately, whether they created it or it was a natural occurrence.
Mjolnir is able to create specific weather on a planetary scale or even beyond if necessary, in defiance of nature, and someone in control of the hammer could make it snow across the planet, regardless of hemisphere, for example. They could also make it rain in space, even though there is no atmosphere, and Mjolnirās power can similarly be used to create solar flairs and manipulate solar winds.
