The spatial distribution of correlation coefficient between hindcast and observation shows that high value areas are different among these methods. So it is hard to say which method is better than others. Thus three predicted results should be considered as well as distribution of correlation coefficient before final extreme high temperature prediction. The predictions by these methods for July, 2007 were generally close to the observation.
