There is one for each world.
The Spirit of Air of Azeroth describes itself as the the winds that warm and cool the earth, the things which fills lungs and keeps beings alive. It carries the birds and insects and dragons, and all things that dare soar to it's challenging heights.
During Thrall's shamans test the Spirit of Air gave him a more light and free sensation than that of the Spirit of Earth. Thrall's soul was filled with laughter and he felt warm winds caress him with various delicious scents, as he floated high above the ground. The Spirit of Air gently let him down on the earth, and left Thrall with a gentle touch before dissipating.
The Spirit of Wind of Outland first communicated with Nobundo after the orcs abandoned Shamanism in favor of practicing with fel magic. Sensing in Nobundo a kindred spirit, feeling neglected and abused because of the cataclysm of Draenor, it saved him from committing suicide with a gust of air, reassuring him that he was not alone and gave him promises of the future.
It, together with the other three elemental spirits of the Outlands, taught Nobundo the path of the shaman and helped him spread those teachings to the remnants of the Draenei society.
This spirit is supportive and often pushes Nobundo forwards with gusts of wind. It's voice is sometimes calm and placating, while at others it is insistent and forceful. The Spirit of Wind taught Nobundo courage and persistence and how to dig deep within and press on in the face of adversity.
