There are many different methods and tools for data analysis in dendrochronology. Modeling is one of them. One of the main issues in modeling is a choice of the main factors. Сlimatic data (temperature and precipitation) are the most common and affordable of them. Based on Vaganov – Shaskin model the new algorithm of visual parameterization of three-ring growth – VS-oscilloscope was developed. Algorithm was tested on different species of woody plants – Larix gmelini and Picea obovata. A new parameterization and analysis of modeling results help to evaluate conditions of area of growth of woody plants, based on dynamic of two climate variables: temperature and precipitation, without adding information about area of growth
