We study topological properties of the QCD vacuum on an 8{sup 3}{times}4 lattice at finite temperature in both phases of QCD. We analyze the distributions of instanton and monopole densities around static color sources and find a suppression of the densities close to external sources. In the confinement phase the suppression occurs in the whole flux tube between a static quark-antiquark pair. We investigate the relation between instantons and Abelian projected monopoles by calculating local correlation functions between topological charge densities and monopole densities. It turns out that topological quantities are correlated over approximately two lattice spacings. The monopole-instanton correlations are rather insensitive under cooling of gauge fields. {copyright} {ital 1996 The American Physical Society.}
