Okay? Still doesn't address that the last time when Thor was unable to reliably use Mjolnir for an extended period of time, he freely embraced his heritage as the God of Thunder and invoked his weather powers sans Mjolnir. Since his rebirth at the hands of JMS, Thor hasn't been disarmed for a lengthy period of time, so your point is non-relevant.
All Mjolnir does is give Thor greater control and on a wider scope. The power of weather manipulation is innate and comes directly from his being.
