Hey, is aerokenisis like wind-control.....like control over the air element? I've tried something like that to move a beach ball in my pool. Not sure if I was actually controlling the wind though. If this is what you are talking about, I suggest practicing with a beach ball or some light object that the wind can easily move. A feather, maybe? Then move up to bigger stuff. I don't think making tornado-strong gust will be very easy, or even possible, really. I usually try on an already windy day so I can just direct wind rather than make my own.
