The generation of zonal flows and zonal fields by finite β drift waves in plasmas with finite ion temperature Ti is investigated. This work extends our earlier work with zero ion temperature. The growth rate of the zonal flow and field is enhanced by finite Ti effects. This leads to a reduction in the critical electron temperature derived earlier for triggering low to high transitions in tokamak plasmas. © 2004 American Institute of Physics.
