Enhancement of the violet K2 emission peak results when the atmospheric layers at heights where Ka forms are moving downward with velocities of 10-20 km/sec or when the K2 layers and those immediately below are moving upward with velocities of 3-7 km/sec. Evidence favoring the former alternative is

Calculations are made for the center-limb variations of the K2 and Kz components of the solar Ca Ii K line using an optically thick model of the chromosphere. The center-limb variations are shown to require an increase of Doppler width with height in the chromosphere and to depend critically upon th
