We comply with the major COSPAR roadmap recommendations and address the Key Science Questions:
•    Can locally excited Sound/Ion Acoustic (S/I-A) wavefields play a role of Local Entropy/Energy Production Sources (LE/EPS) that are enable to modify standard Parker’s SW transonic smooth patterns into the quasi-no-smooth profiles at the vicinity of the critical (sonic) point ?
•    How stable the solar wind patterns are against small perturbations at the critical (sonic) point when the system is driven by LE/EPS.?
Therefore, we formulate the project core problems:
(i)    To focus on the S/I-A wavefields to elaborate consistent wave statistical theory in the vicinity of sonic point. 
(ii)    To perform a stability analysis of the extended mathematical framework for the SW including dynamic equation for S/I-A wavefields as LE/EPS.
