Figure 3.23. Examples of dynamics of when both stochastic and periodic forcing

are present. In all panels the deterministic parameters are the same (

φ

α = 0 . 15 and

ω p = π/ 100) whereas the noise intensity increases from (a) ( s gn = 0 . 05) to (b) ( s gn =

0 . 085) to (c) ( s gn = 0 . 15).
