FOREST FIRES IN CENTRAL YAKUTIA UNDER CLIMATE CHANGE CONDITIONS

Using the boreal forests of Central Yakutia as an example, the authors examine the problem of forest res, which became especially vivid in the current year of 2021 and resulted in multibillion-dollar damage not only to the national economy of the Republic of Sakha (Yakutia), but also to Russia as a whole. At the same time, there is a deep genetic connection in the evolution of forest ecosystems and forest res. It is based on the dependence of the stability of ecosystem functioning on the rate of biogeochemical circulation, modulated by forest res. Monitoring forest res is a key link in the study of the causes and patterns of their occurrence and spread. Along with ground observation posts, route and air patrols of forests, modern monitoring of forest res is supported by remote sensing of taiga ecosystems by EOS satellite programs, which have a MODIS spectroradiometer as part of the onboard equipment of the satellite, which provides a high degree of resolution of space imagery.Global warming of the climate and modulation of climate anomalies by cycles of solar activity are considered as the main cause of res. The materials on the rhythm of heat and moisture supply of the climate of Yakutia are given, which determine the cyclicity of dry intervals and, therefore, the frequency of intensi cation of the dynamics of forest res. The geo-geophysical basis for the development of a long-term forecast of natural and climatic anomalies and re hazard in the forests of Central Yakutia is substantiated.
