The solar eclipse of January 1, 1907 was one of the interesting astronomical events observed in the Russian Empire. Meteorological observations during the eclipse were carried out in various regions, and N. A. Korostelev made a significant contribution to their study. Here are the main information: Place and time of eclipse: This eclipse was total, and the band of total eclipse passed through some areas of the Russian Empire, including Siberia. A partial eclipse was observed on most of the territory of Russia. Meteorological observations: One of the tasks of the observers was to study the changes in temperature, atmospheric pressure, wind and other climatic factors during the eclipse. There was a decrease in air temperature, which was associated with a temporary decrease in solar radiation. Studies have also documented changes in cloud patterns and wind behavior depending on the region. Role of N. A. Korostelev: N. A. Korostelev was a well-known scientist in the field of meteorology and geophysics. He conducted observations of the eclipse, studying its influence on atmospheric processes. His work included analysis of measurements of temperature, pressure and humidity made at different points of observation. Scientific findings: The results of observations made by Korosteleva and other scientists confirmed the connection of solar activity with weather events. Studies of this kind have contributed to the development of meteorology as a science, as well as understanding the interaction between the atmosphere and solar radiation.
