【 摘 要 】

The article deals with current problems of the construction projects adaptation to the global climate change realities. It is shown that the existing regulations do not take into account the risks of extreme thermal processes. The method for the events statistical analysis of the extreme temperature realization are presented. The high-resolution statistical studies results of previously unknown regularities of the maximum and minimum temperatures intensity fluctuations evolution in the period from 1973 to 2009 are presented. Quantitative forecasting of tendencies in realization of the maximum and minimum daily temperatures for the period of all life cycle of buildings is shown. These estimates are intended to account for extreme temperature loads in the design of buildings and engineering systems that forming microclimate of premises. The paper first presented quantum regularities of the air temperature variations in the surface layer of the atmosphere obtained by the authors and previously unknown. As an example, the article deals with the statistical analysis of the extreme temperatures variations in Canberra. The graphic materials over the statistical studies of the maximum and minimum temperatures intensity evolution a period of more than 36 years are presented. The results of studies of integral and differential trends into the maximum and minimum temperatures evolution are given. The article deals with the forecast of the warming expected rate in Canberra until 2067.
