The paper summarizes the results of the annual monitoring of agroclimatic conditions over 1961–1990 and 1991–2020 obtained by both the statistical analysis and the Climate–Soil–Yield simulation system and provides their comparative evaluation. It has been noted that along with growing aridity of the most fertile areas of the steppe and forest-steppe zones, there is an almost universal growth of spring precipitation, which compensates to some extent the negative impact of high summer temperatures on the yield. A significant decrease in the climate-driven productivity of spring wheat from the period of 1961–1990 to the new reference period of 1991–2020 has been revealed for the main grain-producing regions. Estimates of productivity trends for major grain crops, spring and winter wheat, are given in connection with climate change and the development of agricultural technologies.

In the paper, there is an assessment of the dynamics of agroclimatic resources on the territory of the Volga Federal District: the duration of the growing season, the sum of positive temperatures, total precipitation, and photosynthetic radiation. A correlation has been found between the temperature fluctuations in the region and the atmospheric circulation indices (NAO, AO, SCAND, and EAWR). For the territory of Tatarstan, a degree of aridity and waterlogging is evaluated using the agroclimatic indices: the Budyko’s dryness index, the Selyaninov’s hydrothermal coefficient, the Sapozhnikova’s moisture index.

It is shown that the frequency of droughts in the study area in the years of the negative phases of both circulation indices and their extremes in the summer months as compared to other years was higher by five droughts per decade in the Volga and Central Chernozem regions and by three droughts per decade in the northwestern Caspian region. A statistically significant correlation was found between the EAWR in summer and the multidecadal variability of sea surface temperature in the North Atlantic. It was revealed that the increase in the drought frequency in the study area in recent decades has been caused by the restructuring of atmospheric circulation in the Euro-Atlantic sector accompanying the transition of the Atlantic Multidecadal Oscillation (AMO) to a positive phase. An increase in the stability of the EAWR and WP atmospheric circulation patterns was observed, as well as a related significant increase in the frequency of extensive droughts in the study area in 2010–2021. They were accompanied by the weakening of zonal atmospheric circulation in the Northern Hemisphere, the combination of the positive AMO phase and the effects of anthropogenic warming on the atmospheric circulation in the Northern Hemisphere, including those associated with blocking events.</p>","PeriodicalId":49581,"journal":{"name":"Russian Meteorology and Hydrology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139057672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The weather modification activities over NPKP are divided into three stages with the first of 1960–1970s, the second of 1980–1990s and the third of 2000–2010s. In the first stage, significant cloud seeding experiment data and some technologies for the preparation of scientific basis in applying the weather modification theory were accumulated. The cloud seeding experiments in the second stage were hardly carried out over NPKP, however, fundamental researches and investigations, including the cloud and water-power resource explorations on a nationwide scale, were performed. The cloud seeding experiments over the city of Jungsan (39°06′ N, 125°23′ E) of NPKP during the period of 2017–2020 (the third stage) were performed seven times using newly developed 82-mm rockets and fire-AgI shells with a nucleus generation rate of <span>(10^{14}{-}10^{15})</span> <span>(mathrm{g}^{-1})</span>, and the experiment results were presented in detail. All the cloud seeding experiments except of the first experiment obviously showed the effect of precipitation enhancement near the ground (9.1%). In NPKP, weather modification activities using various cloud seeding means with the object of enhancing the precipitation for overcoming severe drought, providing water-power resource security, etc. will continue on the national scale in the future.</p>","PeriodicalId":49581,"journal":{"name":"Russian Meteorology and Hydrology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138548009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
