We investigate the accretion-ejection process of jets from magnetizedaccretion disks. We apply a novel approach to the jet-launching problem inorder to obtain correlations between the physical properties of the jet and theunderlying disk. We extend and confirm the previous works of\citet{2009MNRAS.400..820T} and \citet{2010A&A...512A..82M} by scanning a largeparameter range for the disk magnetization, $\mu_{\rm D} = 10^{-3.5} ...10^{-0.7}$. We disentangle the disk magnetization at the foot point of theoutflow as the main parameter that governs the properties of the outflow. Weshow how the four jet integrals known from steady-state MHD are correlated tothe disk magnetization at the jet foot point. This agrees with the usualfindings of the steady-state theory, however, here we obtain these correlationsfrom time-dependent simulations that include the dynamical evolution of thedisk in the treatment. In particular, we obtain robust correlations between thelocal disk magnetization and (i)the outflow velocity, (ii) the jet massloading, (iii) jet angular momentum, and (iv) the local mass accretion rate.Essentially we find that strongly magnetized disks launch more energetic andfaster jets, and, due to a larger Alfv\'en lever arm, these jets extract moreangular momentum from the underlying disk. These kind of disk-jet systems have,however, a smaller mass loading parameter and a lower massejection-to-accretion ratio. The jets are launched at the disk surface wherethe magnetization is $\mu(r,z) \simeq 0.1$. The magnetization rapidly increasesvertically providing the energy reservoir for subsequent jet acceleration. Wefind indication for a critical disk magnetization $\mu_{\rm D} \simeq 0.01$that separates the regimes of magnetocentrifugally-driven and magneticpressure-driven jets.
