A kinetic simulation code based on the gyrokinetic ion dynamics in global general metric (including a tokamak with circular or noncircular cross{section) has been devel- oped. This gyrokinetic simulation is capable of examining the global and semi{global driftwave structures and their associated transport in a tokamak plasma. We inves- tigate the property of the ion temperature gradient (ITG) or ·i(·i · @'nTi=@'nni) driven drift waves in a tokamak plasma. The emergent semi{global drift wave modes give rise to thermal transport characterized by the Bohm scaling.
