Abstract: The recent progress in our understanding of the dynamics of multi-phase interstellar medium (ISM) is dramatical. ALMA may provide an opportunity to open a new era for the investigation of cold, warm, and non-thermal components of interstellar medium. Non-linear perturbations (e.g., shock waves or time-dependent radiation field) lead to the interchange between warm phase and cold phase via thermal instability. Dynamical modelling of the phase transition dynamics is essential in describing ubiquitous turbulence in ISM and the formation of molecular clouds. A concept of magnetically multi-phase medium is also introduced. Recent finding of the magnetic field amplification in the blast wave propagating in magnetized multi-phase ISM is providing an interesting scenario for rapid acceleration of cosmic rays.
