✦ Synopsis

The possibility of surge formation as a result of plasma 'raking-up', the latter being associated with the growth of the local magnetic field in the solar atmosphere, is considered in this paper. The question is treated numerically in the MHD approximation for the case of the dipolar magnetic field. It is shown that the field growth results in the appearance of relatively dense condensations stretched along the axis of a dipole. Simultaneously the plasma acquires the upward velocity along force lines which leads to the formation of a surge. Some properties of this surge model are discussed.

A simple and reliable method has been established for the definition of the depth of formation of lines in a stellar atmosphere. It is based on the determination of the level of emission of the reemitted line radiation. The new definition, which is applied in this paper to the solar case, does not s
