Abstract:

I review the capabilities of Htex2html_wrap_inline307 observations to constrain some aspects of the current models of the interstellar medium. In particular, it is shown that turbulence is a necessary ingredient of any viable model, since most of the energy produced by supernova explosions and ionizing radiation is stored in kinetic form in the ISM. Various forms of turbulent energy dissipation, including cloud collisions, are analyzed. Two additional aspects, concerning the existence of galactic fountains and their relation with High Velocity Clouds, and the extended ionized layer of spiral galaxies are discussed; some crucial experiments are suggested.

Keywords: interstellar medium - turbulence
