Geoinformation assessment of climatic conditions of the Saratov region

Summary. The article presents the results of geoinformation analysis of point data obtained from the weather stations of the Saratov region. The results of the study reflect the regional features of global warming. The outcomes obtained can be used to adapt agriculture to new conditions.

Introduction. In regions with arid climate, an urgent issue is the assessment of climatic conditions and monitoring of their changes in the course of global warming. Landscapes of arid territories are the least resistant to changes in external conditions. The issue of climate monitoring is especially relevant for regions with a high share of the agricultural sector and leading positions in terms of agricultural production. With climate change without adaptation of agriculture, the efficiency of agriculture can significantly decrease. The purpose of this study is to assess climatic features of the Saratov region, to identify dynamic characteristics which can be used to make decision in agricultural production in future.

Object. The object research is the climate of the Saratov region.

Materials and methods. Point data of the weather stations of the Saratov region, adjacent regions and Kazakhstan were used in research. The data was obtained using the AISORI and Weather and Climate services. Statistical data processing was performed in Microsoft Excel and Graphical Analysis. The creation of cartographic materials was carried out by the interpolation method (IDW method) in QGIS 3. Using the interpolation method gives greater accuracy of the results in comparison with global data.

Results and conclusions. As a result of data analysis and mapping, the features of the climate dynamics of the Saratov region against the background of climate changes have been revealed. It has been established that the air temperature has been increasing everywhere at a rate of 0.038 °C per year since. It has increased by 2.17 °C over the past 57 years. Precipitation has increased by an average of 23.4 mm, but in the south-east of the region, moisture availability is decreasing from year to year.
