This paper studies a periodically perturbed Lorenz-like equation.We obtain three types of attractors: (i) periodic sinks, (ii) H¶enon-like attrac-tors, and (iii) rank one attractors. Among the three, (i) represent the stabledynamics of equation, and (ii) and (iii) represent chaotic behaviors character-ized by an Sinai-Ruelle-Bowen(SRB) measure. Each attractor admits an basinof positive Lebesgue measure, hence we observe it in numerical simulations.
