Aerokinesis

First of all go outside and sit down somewhere comfortable preferably on a windy day. Feel the wind, each separate current, feel the wind brush past you and move past you. Now imagine altering the currents by making them blow harder or faster etc...
Say a chant while imagining this, anything would do.

Example: By the winds I demand a gale, one strong enough to make ships sail, one powerful enough to make brick walls fail.

Then repeat it over and over again. It doesn't have to rhyme and I suggest coming up with your own.
