Fuuton: Goukuuhou (Wind Style: Great Air Cannon)
The user, by molding his wind chakra through his lungs, shoots a ball of condensed air capable of knocking back the enemy and surrounding objects. A great overall basic tech, the main downside is basically the range and the small area of effect it has. The plus side is the speed of making the jutsu and the speed of the air "bullet".
I couldn't find an image but the jutsu seems to have been used by seimei (the ex-sand weapon specialist during one of the filler arcs in the first naruto series)
Fuuton: Kami Kaze (Wind Style: Divine Wind)
The user channels his wind chakra to produce small tornadoes that can be directed at will and are very usefull in conjunction with a fire jutsu. Downside is the very short range and the fact that one has to create the vortexs near him and then send them towards the enemy giving the enemy time to counter. Plus side is the combo possibilities.

Fuuton: Kami Oroshi (Wind Style: Divine Wind From The Moutain)
The user creates a vortex of wind that he can shape and use almost at will. He can use it with a fire jutsu to produce a stream of fire towards an enemy. The overall attack speed is not very high and still leaves openings for the enemy to counter. Can be used as a sneak attack creating the vortex in the blind spot of the user for example.

Sensei, one question: Combo jutsu. If one uses a b-rank fire powered by a b-rank wind, does it translate into an a-rank attack? How does one figure the overall power of the resulting jutsu?
