Scatter plots of ﹩\overline{H}﹩ against (a) ﹩{\overline{{{\rm{\Phi }}}_{0}}}^{2}﹩, (b) ﹩{\overline{{{\rm{\Phi }}}_{1}}}^{2}﹩, and (c) ﹩\overline{{{\rm{\Phi }}}_{0}}\,\overline{{{\rm{\Phi }}}_{1}}﹩ for all Cycle 24 extrapolations. Models with different smoothing b0 are shown by different weights (as per Figure 3). There is no direct relationship in (a) or (b), but least-squares linear fits are shown in (c).
