The Spatio-Temporal Variability of the Distribution of Climate Indicators of Thermal Agro-Climate Resources (the Ararat Valley and the Foothill Zone, Armenia)

Abstract—In this work, the characteristics of thermal agro-climate resources of the Ararat valley and the foothill zone are studied and calculated and 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 the theoretical and informational foundations. The daily data of actual observations of meteorological stations of the Hydrometeorology and Monitoring Center of the SNCO of the Ministry of Environment of the Republic of Armenia in the study area, as well as agro-climate reference books and yearbooks were used as the source material. The following methods were applied in the work: mathematical-statistical, extrapolation, interpolation, analytical, correlation methods, as well as the methods of analysis and analogue. 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 climate indicators of thermal agro-climate 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 taken into account. Measures for adapting agricultural production to climate change are proposed. The results we 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-climate cadastres of territories and climate services for sectors of the national economy.
