Abstract

In the work, based on a number of observations at station 29645 Kemerovo for the period from 1951 to 2023, the long-term variability of air temperature and precipitation was investigated. For the first time for the Kuzbass Botanical Garden, climatic norms for the period 1991–2020 were estimated, using linear trend analysis, the rates of change in climatic indicators were estimated. It has been established that climatic indicator on the territory of the Kuzbass Botanical Garden for the period 1951–2023. have an upward trend. However, the temperature growth rates are slightly lower than those noted for Western Siberia. Annual precipitation is characterized by stable growth throughout the study period. However, there is some instability of this trend. It has been shown that the climatic standards of air temperature and precipitation in the modern period differ significantly from the base period of 1961–1990 proposed by the WMO.
