ABSTRACT:The kinematic structure of cirrus features was examined in seven cirrus fields by identifying the velocity intervals in the 21-cm line
emission.
The velocities of the H I structures associated with the infrared cirrus
span a large range.
Cirrus features are sometimes superpositions of
kinematically distinct components which can be separated on the basis of kinematic
information.
The results of the analysis suggest that anomalous velocities are common
among cirrus features and that some acceleration mechanism is an important
aspect of the general cirrus phenomenon.
