Winds of Watoomb
Whirling Winds of Watoomb,
Wild Winds of Watoomb,
Great Winds of Watoomb
 And now let the Whirling Winds of Watoomb rise from the nether regions...to carry you back from whence you came!
— Doctor Strange
Winds of Watoomb was a spell that called upon the powers of Watoomb to conjure powerful mystical air current. 
Doctor Strange first used the Whirling Winds of Watoomb to send the Dread Dormammu back to his dimension. He used the spell with similar effects against  Umar the Unrelenting.
Doctor Strange casting the Winds of Watoomb to banish Umar the Unrelenting Xander actually conjured the Winds of Watoomb to battle against Doctor Strange. Though he struggled to concentrate his powers, Doctor Strange was able to cease the winds.
Doctor Strange frequently uses the Winds of Watoomb to strengthen the
Shield of the Seraphim.   
When the serpent
demon Damballah attacked Doctor Strange with the snakes, Strange stuns them with the Maze of Munnopor and used the Winds of Watoomb to return them to their cages in the pet shop.
When Doctor Strange was being attacked by the
Black Knight, he used a combination of the Winds of Watoomb and the Fangs of Farallah to subdue him.
Clea and Doctor Strange attempted to combine Watoomb's Wind and
Ikonn's Seeming to eternally banish Orini and Umar. Although Clea tried to break the spell before it could be completed, Strange was complete and seal it.
