The Parker Solar Probe and Solar Orbiter missions provide unprecedented observations near the solar wind’s source, complemented by historical Helios data and continuous 1 AU measurements from Wind. These observations highlight the need for integrating the kinetic, fluid, and magnetic processes in the multiscale solar wind model. Recent advances in linear theory, quasi-linear (QL) theory, and fully nonlinear simulations offer valuable, complementary tools for exploring these dynamics. In particular, QL theory often quite accurately replicates the complex nonlinear dynamics in PIC or hybrid simulations. Unlike the fully nonlinear simulations, which require significant computational resources, the QL approach offers an elegant and accessible method, making it particularly suitable for rapid analyses (~ 0.5 minute/run on a standard PC). This session invites contributions on linear, QL, and simulation-based studies, observational comparisons, and related topics such as stochastic heating, collisional effects, and multi-point measurements, to better understand solar wind dynamics across scales.
