Caption: Fig. 5.

Cloud density (top) and velocity components (middle, tangential; bottom, radial) plotted vs. spiral phase, from RS87 dissipative simulations, case M. For a tightly wound spiral, a cut through the spiral phase is roughly equivalent to a cut in radius. This particular figure is at a time step 1170 Myr.
