An article by Jamal Huseynov, a doctoral student at the Department of Hydrometeorology of the Caspian Sea of the Institute of Geography named after acad. H.Aliyev, was published in the Russian journal “Hydrometeorology”. “Modern features of the spread of perennial temperature regime in the territory of Azerbaijan. Research and forecast ». As a result of mathematical, statistical and cartographic analysis conducted on the territory of Azerbaijan, it was found that the temperature regime of the republic varies from north to south and from plains to highlands. Also determined long-term average and seasonal indicators of temperature in different regions of the country. The maximum values of the long-term average temperature were observed in the Kura-Araz lowlands in the range of 14.6-15.4 ° C. The higher the altitude, the lower the average temperature. The results can be used in future studies of the climatic regime, its variability, the creation of agriculture, tourism and other large industries in this area.
