Narrative:

Crossing a line of storms; we were at FL450. It appeared the storms were about 6;000 feet below us. All of the sudden we got into moderate turbulence and wave which caused the plane to climb and kick off the autopilot. It was caused by wave and turbulence due to the storms. The PIC took control of the plane and got us calmly back down to altitude. No suggestions at this time.
