Abstract

An analysis of time series of meteorological parameters has shown that long-term time intervals (stages and steps) with almost uniform climate regime do exist. These stages and steps are due to existence of steady periods in basic climate-forming factors - atmospheric circulation, solar activity and other astronomical and geophysical factors. New concepts of climatic regime norm for stage and general climatic norm are introduced. A method for revealing climatic stages and steps and determining climatic norms is proposed based on integral estimation functions of radiative, thermal, water and other regimes of a climate process. Time intervals with relatively constant climate are determined for 16 weather stations of West Siberia on the basis on the analysis of secular series of cumulative sum of annual air temperatures and annual precipitations.
