In recent years, an increase in temperatures has been observed across all seasons in Azerbaijan.

This was reported to AZERTAC by Hasan Nabiyev, a leading researcher at the Climate Department of the Institute of Geography under the Ministry of Science and Education, PhD in Geography.

He stated that, in order to investigate the causes of rising temperatures, the circulation classification of B.L. Dzerdzeyevski was used. The analyses showed that the main factors creating favorable conditions for temperature increases at all observation points are the meridional northern 12a type and the meridional southern (13l) processes, which have become more frequent in recent years.

According to the scientist, in order to determine the reasons why summers, especially July and August, have become hotter, the recurrence frequency of circulation types during those months was studied. The results revealed that the 13l, 10b, and 9a meridional circulation types prevail during this period.

It was also noted that since 1975–1980, the rise in temperatures in Azerbaijan has coincided with the strengthening of meridional circulation and the weakening of zonal processes.

Under such circulation conditions observed during summer months, anticyclones formed in the polar regions of the Northern Hemisphere move southward and merge with the subtropical anticyclone. As a result, a ridge of high pressure is formed, blocking the westerly air flows coming from the Atlantic Ocean.

At the same time, the influence of anticyclones formed over Eastern Europe and Siberia extends to the South Caucasus, including the territory of Azerbaijan. This leads to the formation of stable weather conditions across the country and causes temperatures to rise even further.
