(a) The energy distribution of fGn over the IMFs, its upper and lower bounds with 99% confidence interval. The energies of individual IMF of daily minimum temperature signal indicate that the 8th one is the starting IMF to represent the annual cycle. (b) The separation of annual cycle of daily maximum temperature. The preprocessed climate signal (top), extracted annual cycle (middle), and the residual signal (bottom).
