| Abstract: | The spatial distribution of long-term average air freezing and thawing indices in Yakutia was investigated using the data
of 156 meteorological stations located in this region. The regularities of variations of air freezing and thawing indices
are revealed depending on the impact of zonal, regional, and local environmental factors. The concrete correlations with the
latitude, longitude, and altitude are obtained. The effects of climatic processes and relief of regional and local levels
are estimated. Based on the revealed relationships, the 1 : 5000000-scale maps are plotted to demonstrate the spatial variations
of air freezing and thawing indices. |
