Abstract

The article studies the general trends in the temperature regime of the Kalbajar, Lachin, Gubadli, Jabrayil, and Zangilan regions, which are currently included in the Eastern Zangezur economic region, based on the MERRA-2 (Modern-Era Retrospective analysis for Research and Applications, Version 2) reanalysis data for the period 1980-2022. During the study, an increasing trend in average annual and seasonal temperatures was detected for the area during the period under review. The temperature increases by season and by annual period are statistically significant at the 5% level of confidence. The calculations showed that the average annual air temperature in Kalbajar and Lachin regions increased by 0.9°C in the period 2001-2022 compared to the period 1980-2000. This increase was recorded in Gubadli, Jabrayil, and Zangilan regions by 1.1°C. These results are consistent with the results obtained in other regions of the republic. When looking at the temperature changes by months for both periods in the regions, the largest average temperature increases by months in Kalbajar and Lachin regions were recorded in February (1.7 °C), March (1.8 °C), and October (1.3 °C). In Gubadli, Jabrayil, and Zangilan regions, the temperature increased by 2°C in February, by 2.6 °C in March, and no changes were recorded in April.
