Margaryan V.G., Gaidukova E.V., Sedrakyan A.M. SPATIAL-TEMPORAL VARIABILITY OF THE DISTRIBUTION OF CLIMATE INDICATORS OF THERMAL AGROCLIMATE RESOURCES (ARARAT VALLEY AND FOOTHILL ZONE, ARMENIA) // Arid Ecosystems. 2023. Vol. 29. № 4 (97). P. 135-147. | PDF

 In this work, the characteristics of thermal agro-climatic resources of the Ararat valley and the foothill zone are studied and calculated, the patterns of their spatial and temporal distribution, as well as interannual variability, are analyzed and evaluated. Previously published works and relevant studies served as theoretical and informational foundations for this work. Daily data of actual observations of meteorological stations of the «Hydrometeorology and Monitoring Center» SNCO of the Ministry of Environment of the Republic of Armenia in the study area, as well as agro-climatic reference books and yearbooks were used as the source material. The following methods were applied in the work: mathematical-statistical, extrapolation, interpolation, analytical, correlation, as well as methods of analysis and analogue.

It turned out that the territory of the Ararat valley and the foothill zone, which has a relatively arid climate, is the most favorable agricultural region of the republic in terms of climatic indicators of thermal agro-climatic resources. The thermal conditions of the region are favorable for the growth and development of various crops; however, the danger of late spring and early autumn frosts must be considered. Measures for adapting agricultural production to climate change are proposed. The results obtained can be used in planning the development of agricultural production on the territory of the Ararat valley and the foothill zone, in the development of agro-climatic cadastres of territories and climatic services for sectors of the national economy.

Keywords: dates of stable transition of the average daily air temperature through 0, 5 and 10°C in spring and autumn, climatic spring, climatic autumn, growing season, climate change, Ararat valley and foothill zone, Armenia.
