Narrative:
It was a normal flight climbing out of FL315 to assigned altitude of FL330. There were thunderstorms in the area we were deviating around. We had a large bump that sounded like a gear door closing hard. All instruments and gauges were normal. Just prior to leveling off at FL330 at climb power; we had continuous bumps and aircraft was shaking. Looking at the engine instruments the right engine was surging. N1 was in the red around 105% and itt was in red around 1;000 degrees. I was pilot not flying and pulled right throttle back to around 60% (the engine smoothed out below 90%). We determined that it was a compressor stall and advised ATC we need to return to [departure airport] (about 60 miles behind us). We did not declare an emergency or shut the engine down; it was stable at 60% power and figured we might need it. The right engine was left at 60% at was in normal operating range (all green gauges). We ran a rough engine check list and followed the G200 aircraft flight manual (afm). We landed safely.
