We have performed self-consistent 2.5-dimensional nonsteady MHD numericalsimulations of jet formation as long as possible, including the dynamics ofaccretion disks. Although the previous nonsteady MHD simulations forastrophysical jets revealed that the characteristics of nonsteady jets aresimilar to those of steady jets, the calculation time of these simulations isvery short compared with the time scale of observed jets. Thus we haveinvestigated long term evolutions of mass accretion rate, mass outflow rate,jet velocity, and various energy flux. We found that the ejection of jet isquasi-periodic. The period of the ejection is related to the time needed forthe initial magnetic filed to be twisted to generate toroidal filed. We compareour results with both the steady state theory and previous 2.5-dimensionalnonsteady MHD simulations.
