... Stotskii A. A. Path length fluctuations through the Earth troposphere: turbulent model and data of observations. The spatial and temporal structure functions of path length the Earth troposphere for the whole space and time ranges constructed on the base of turbulence theory are considered. These structure functions include three domains: a power law of 5/3 (three-dimensional turbulence), a power law of 2/3 (two-dimensional turbulence) and saturation. ...

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.
