Microclimatic and thermal balance studies in the natural conditions of the middle categories of South Yakutia

The article reveals the activities of the Zolotinka geocryological station in South Yakutia, one of the BAM expeditions of the Institute of Permafrost, USSR Academy of Sciences. Relevance. The article is dedicated to the 95th anniversary of the birth of Maria Gavrilova, a climatologist, permafrost scientist, famous in Russian and world science, Doctor of Geographical Sciences, professor, Honored Scientist of the Russian Federation and the Republic of Sakha (Yakutia), academician of the Academy of Sciences of the Republic of Sakha (Yakutia), the Russian Academy of Natural Sciences 1. The BAM expeditions of the Institute of Permafrost were united by a common research topic “Prediction of the evolution of the cryolithozone in the development of the territory adjacent to the BAM railway” to predict the state of geocryological conditions and make practical recommendations for the construction of engineering structures in settlements, stations and roads in the Maly BAM zone 2. In different natural conditions, landscapes of the foothills of the Stanovoi Ridge of South Yakutia (valleys, watersheds, as well as on the slopes of different exposures), special permafrost conditions are formed associated with the patterns of heat exchange of the upper layers of the earth’s crust – the earth’s surface – the atmosphere 2. To identify permafrost, microclimatic and thermal balance conditions in the midlands of South Yakutia, on the territory of the village of Iengra of the Neryungrinsky City Council, on September 1, 1975, the Zolotinka geocryological station was organized under the leadership of Dr. Gavrilova. The year-round station conducted three full cycles of microclimatic and thermal balance studies from 1975-1978. A retrospective approach to the topic of the BAM expedition organized by the Institute of Permafrost made it possible in this article to familiarize and summarize in detail the scientific and organizational activities of Maria Gavrilova on the work of the Zolotinka geocryological station in 1975-1978.
