Air temperature change manifestation at the Zhytomyr territory

Abstract

The territory of cities with a changing environment, a significant density of population, industrial and transport facilities, daily activities that ensure its vital activity and cause significant greenhouse gas emissions, causes a significant contribution to climate change, which is one of the most acute environmental problems of our time. Purpose. To assess the manifestations of air temperature changes in the city of Zhytomyr for the period 2000-2022. Methods. Statistical, the coefficient of deviation essentiality of air temperature from the average long-term values was calculated in accordance with the methodology of Pede D.A. . Results. The information base of the research was the data on average annual and average monthly air temperatures in Zhytomyr of the Zhytomyr Regional Centre for Hydrometeorology. It was determined that in the period 2000–2022, the air temperature in the city increased by 1.9 °C compared to the climatic norm. 2015, 2019, and 2020 were the warmest during the period of our observations. Based on the calculation of the coefficients of of deviation essentiality of air temperature deviations from long-term average values, it was determined that for individual months of the year for the period 2000–2022, 2.9% of recorded conditions were close to extreme, and 31.9% – recorded conditions that differ significantly from the perennial average, the remaining 65.2% have conditions close to normal. According to the years of observation, temperature conditions that are significantly different from the long-term average occurred in 2002, 2007, 2008, 2015-2020, close to normal - during the rest of the years. Conclusion. The obtained results are important for understanding the problem of increasing air temperature in Zhytomyr and developing measures to adapt to climate change at the local level.
