  The nature of lag variation of Galactic black holes remains enigmatic mostly
because of nonlinear and non-local physical mechanisms which contribute to the
lag of the photons coming from the region close to the central black holes. One
of the widely accepted major sources of the hard lag is the inverse
Comptonization mechanism. However, the exact reason or reasons for soft lags is
yet to be identified. In this paper, we report a possible correlation between
radio intensities of several outbursting Galactic black hole candidates and
amounts of soft lag. The correlation suggests that the presence of major
outflows or jets also change the disk morphology along the line of sight of the
observer which produces soft lags.
