In this study, in order to evaluate the SOL width of both density and temperature, we analyze Hasegawa-Wakatani model which includes the temperature fluctuations. Different instability regimes, i.e. drift waves and linearly unstable convective cells are studied. It is shown that convective cells are favorable in terms of the heat load reduction on the divertor. Implications on future devices, such as JT-60 SA, ITER, etc, are discussed.
