Empirical mode decomposition of the standardized potential ﹩\hat{{\rm{\Phi }}}﹩. The IMFs and the residual are shown. IMF1 and IMF2 capture the shortest periods, i.e., periods of approximately 11 yr and 22 yr, respectively. The residual shows the monotonic trend of the signal. The ordinates have the same scale, so the IMFs can be easily compared.
