Climatic Characteristics

The paper presents a series of maps of extreme climatic characteristics for the Ural region and their changes under climate warming observed in last decades. We calculate threshold, absolute and percentile-based indices with the use of daily temperature and precipitation dataset of 99 weather stations of Roshydromet. Extreme climatic characteristics were averaged by moving 30-year periods from 1951 to 2010 for temperature and from 1966 to 2015 for precipitation. The regression-based interpolation was used for mapping climatic extremes taking into consideration the influence of topography. Elevation and general curvature of the terrain are considered as independent variables. In addition, the changes of extreme characteristics between the 30-year periods were estimated. As a result, a series of maps of temperature and precipitation extremes for the Ural region has been created. The maps present not only spatial distribution of the climatic extremes, but also regional features of their changes under climate warming. In general, the revealed changes in extremes in the Ural region correspond to the trends observed on the most of the territory of Russia. There is a substantial decrease of the number of extremely cold days in winter, and the minimum winter temperature has a strong positive trend (up to 1-5°C/30 years). The maximum temperature in summer has a positive trend in most of the territory, but the increase rate does not exceed 2°C between 1951–1980 and 1981–2010. The precipitation extremes also increased up to 0.5-1.5 mm when comparing 1966–1995 and 1985–2015 periods.

The article presents an analysis of the climatic characteristics of the regimes of air temperature and precipitation in the Republic of Bashkortostan in the period 1966-2015. For this period, the basic climatic characteristics are calculated. To identify changes in the analyzed values, trend analysis was used. Cases of air temperature anomalies and precipitation totals are examined in detail according to the criteria of intensity and duration of their existence for different time periods. Assessment of the influence of circulation factors on the indicators of the temperature-humidity regime of the region was carried out using a correlation analysis between them and the atmospheric circulation indexes - North Atlantic, Arctic, Scandinavian, Atlantic multi-decade oscillations.

Climatic Characteristics

In recent years, rising temperatures and changes in precipitation patterns have a significant impact on agriculture. This paper presents analyses of selected climatic characteristics of the South Moravian region. The evaluation was based on the data from the Czech Hydrometeorological Institute. Climatic data for future periods were gained using the A1B emission scenario. With regard to the agricultural activity of this region, climatic characteristics (average air temperature, heat waves, average precipitation and periods without precipitation) were selected and compared in the following three periods 1961–1990, 2021–2050 and 2071–2100. The results showed an increase of the average air temperature, increase in the number of tropical days and days in heat waves. It was also found that as a result of rising air temperatures and different distribution of precipitation, the period of drought will significantly prolong in the future. Very unfavourable climate situation is expected in the particular period of 2071–2100 in this region. Increasing drought, predicted by climate models, presents major problem for the agriculture of South Moravia. It is necessary to adapt to these anticipated changes not only in the agricultural activities but also in the landscape management in general.

Using the system approach, we have developed a simulation model for the long-term forecast of the content of toxic chemical elements in grain crop yield. The study was carried out by the example of wheat cultivated in Altai Krai — one of the main grain-producing regions of Russia. Wheat crops were sampled in 10 municipal districts of Altai Krai, which characterize seven different edaphic-climatic zones. The average long-term values of mean monthly air temperature and monthly precipitation for each sampling area were identified using GIS and data of the Interactive Agricultural Ecological Atlas of Russia and Neighboring Countries. A total of 19 chemical elements were considered, i.e. Pb, As, Cd, Hg, Na, Mn, Zn, Cu, Fe, Co, etc. It is shown that content of Pb, Na, Mn and Cu in wheat depend on climatic characteristics of the cultivation area. Regression dependences of element content on the average long-term air temperature and precipitation were established. Based on normalization and spatial generalization of air temperature and precipitation providing the uniform dynamics of their relative monthly values (in percent) throughout the study area, a forecast of their changes was made for 2030. A procedure for grain sampling, GIS technologies for processing meteorological and cartographic data, methods for predicting regional climate changes and establishment of quantitative relationships of chemical elements content in grain with climatic characteristics – all together make up the integral predictive simulation model for toxic substance content in grain crop yield. The model was used for estimation of Pb, Na, Mn, Cu changes in wheat by 2030. The lead (Pb) content in wheat crop delivered to elevators from certain municipal districts will exceed the maximum allowable concentration for breadgrain after 2030. Unlike Pb, Na, Mn, Cu, the content of other metals in wheat grain weakly correlate with long-term changes in air temperature and precipitation; therefore, it can hardly change significantly.

Sowing Seed

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.
