Yep. Of all the Winds of Magic, Ulgu is the most attuned to the classical element of Air.
That said, as far as I understand in Warhammer magic talents don't generally come with a "flavor" of one of the Winds - in fact, it takes special training and effort for beginning mages to learn how to draw on only one of the Winds.
There are rare exceptions (like the Azyr Patriarch), but most talents the colleges pick up could do equally well in any of the Eight Winds, with most arrivals being sorted by practical and political reasons as opposed to magical ones.
