Illustrations of amplification range and strength reduction as functions of AN_h using the dynamic two-class model (blue), static two-class model (red) and one-class model (green). The minimum control strength for amplification suppression is the value of control strength κ* such that scaled exceeds unity for all control strengths κ ∈ [0, κ*]. The maximum scaled is the value of scaled at the peak of a model's versus κ curve for a given value of AN_h. (a) Amplifaction range reduction 1/γ = 15 days, (b) amplifaction severity reduction 1/γ = 15 days, (c) amplifaction range reduction 1/γ = 9 months, (d) amplifaction severity reduction 1/γ = 9 months, (e) amplifaction range reduction 1/γ = 5 years and (f) amplifaction severity reduction 1/γ = 5 years.
