Coupling between active galactic nuclei (AGN) and the circumgalactic medium(CGM) is critical to the interplay between radiative cooling and feedbackheating in the atmospheres of the universe's most massive galaxies. This paperpresents a detailed analysis of numerical simulations showing how kinetic AGNfeedback with a strong momentum flux interacts with the CGM. Our analysis showsthat large scale CGM circulation plays an important role in reconfiguring thegalactic atmosphere and regulating the atmosphere's central entropy level. Wefind that most of the AGN energy output goes into lifting of circumgalactic gasrather than heating of atmospheric gas within the galaxy, consequentlyreconfiguring the circumgalactic medium (CGM) in our simulations. Large scale(10s of kpc) circulation of the CGM on ~ 10-100 kpc scales therefore plays acritical role in preventing over-cooling of gas in these simulated galaxies.The simulations also show that our choices of accretion efficiency and jetopening angle significantly affect the AGN-CGM coupling. Reducing the jetopening angle to quarter of the fiducial opening angle increases the jetmomentum flux, enabling it to drill through to larger radii without effectivelycoupling with the CGM at the center ( $r < 5$ kpc). Outflows with a lowermomentum flux decelerate and thermalize the bulk of their energy at smallerradii ($r \lesssim 10$ ).
