4. Conclusion

[27]  Thus the values of turbulent velocities are from several km s-1 to several tens of km s-1, displaying certain regularities: turbulent velocities are maximum in CHs and minimum in a cavity around a quiescent prominence; seemingly, the turbulent velocity in quiescent loops does not depend on the loop temperature and is consistent with the values of x in the diffuse corona. As we discussed before [Delone et al., 2003b], turbulent velocities probably have MHD nature and are caused not only by temperature, density, and ordered-motion velocities, but also by the MF variability. Ordered velocities in various structures may vary from several km s-1 to (100-200) km s-1 (and perhaps to higher values, because in many cases only the Doppler component of the total velocity can be measured). Probably, ordered velocities have on the average greater values than turbulent velocities; to some extent, these velocities can be interrelated, because in dynamic structures both x and V are higher than in quiet ones. This is inferred from the observations of dynamic loops and jet structures visible in the transition region lines.
