Microscopically, around melting, a cold liquid can be viewed as a strongly coupled
many-body system under weak stochastic thermal agitation, which excite collective motion
over a broad range of scales. Nevertheless, whether multi-scale modes can be decomposed
from particle micro-motion information and how modes are coupled remain open issues. In
this work, these issues for the cold 2D Yukawa liquids are numerically addressed for the first
time through empirical mode decomposition method. Spatiotemporal mode-mode cascading
is observed. Their correlation to the large scale structural rearrangement is presented and
discussed.
