Abstract Coronal bright points are known to be magnetic in nature. A two-dimensional MHD code was devleoped to investigate the rsponse of a stratified atmosphere to a localized magnetic structure. If a bright point occurs at a region where flux tubes of opposite polarity have encountered by chance it is found that, in the presence of stratification, a net upward mass flux results. Upflow velocities of up to one half of the Alfven speed are produced. The implications of the results for mass outflows from bright points in coronal holes are discussed. 24 references.
