Description:In the real world, we see physical, biological, and geophysical systems that consist of large number of interacting dynamical entities to form a complex structure. In this context the study of emergent dynamics of individual systems is largely studied and had been applied to its contribution towards control of chaos, self organization, synchronization etc. In many such cases the dynamics of individual entities follow different time scale for their evolution in time. In our work we consider standard non linear systems with differing time scales interacting with each other. We start by taking the simplest case of two dynamical systems among which one is slow and one is fast, coupled by diffusive function. By tuning the parameters in concern we report amplitude death as the main result and other emergent dynamics such as frequency synchronization, two frequency state etc. As an important special case, we revisit the well-known model of coupled ocean atmosphere system used in climate studies for the interactive dynamics of a fast oscillating atmosphere and slowly changing ocean that indicates occurrence of multi stable periodic states and steady states of convection coexisting in the system.
