Nonlinear plasma waves, their evolution and other related processes are important for understanding energy release and transport in space plasmas. Recent THEMIS and Cluster missions provided excellent tools to study magnetospheric, bow shock and solar wind nonlinear waves, wave-particle and wave-wave interactions. The STEREO mission provides an important contribution to understanding wave processes in the solar wind. The session is open to researchers working in the areas of solar-terrestrial plasmas. Theory, simulation and data analyses papers are welcome.
