Figure 75. Analog simulations of forcing functions for
Model II (Model in Figure 12). Surface water area under
five degrees of damping (reduced oscillation) and product
of solar radiation and surface water area under five
degrees of damping.

 f) no oscillation
 g) slight oscillation
 h) increased oscillation
 i) slightly less oscillation than present
 j) present conditions

NOTE: See Appendix Table B-1 for mean, maximum, and
minimum acreages of water area under different
oscillations.
