Abstract
We propose and investigate a new formation mechanism for globular clusters in which they form within molecular clouds that are formed in the shocked r egions created by galactic winds driven by successive supernova explosions shortly after the initial burst of massive star formation in the galactic c enters. The globular clusters have a radial distribution that is more exten ded than that of the stars because the clusters form as pressure-confined c ondensations in a shell that is moving outward radially at high velocity. I n addition, the model is consistent with existing observations of other glo bal properties of globular clusters, as far as comparisons can be made.
