Results of experience in division of «steady widespread» and «excess heavy» parts of liquid precipitation by criterion of their intensity are considered in this paper. New physical approach is based on distinction of main precipitated ascending movements, causing formation of heavy or steady widespread precipitation. The data on pluviographical observations for ten summer periods (1984 - 1993) at one post in Penza region are analyzed. The non-standard technique of processing and analysis of the data is used.
