For each zone, the changes in the total seasonal duration of heat waves since the beginning of the 20th century and associated changes in the average seasonal temperature in the region are analyzed. For the periods 1901–1960 and 1961–2020, the total number of waves for different gradations of their duration has been obtained. A catalog of the largest (extreme) heat waves with a duration of three weeks or more with possible transitions between the zones has been compiled: there has been only 11 such waves since the beginning of the 20th century, including 6 waves after 2000. For these heat waves, their correspondence to the phases of the EA/WR, AMO, and PDO climate modes was analyzed. For three of them (1972, 2010, and 2016), the description of the geographical structure (temperature, mid-tropospheric circulation) and evolution according to the data on the circulation in the middle (including the correspondence to the episodes of anticyclonic quasistationary circulation (AQC)) and upper troposphere was performed. It has been found that at the stage when the tropospheric ridge over European Russia penetrates into high latitudes, additional blocking structures similar to the Rossby wave breaking appear, which seemingly prolong the persistence of the AQC region over European Russia.</p>","PeriodicalId":49581,"journal":{"name":"Russian Meteorology and Hydrology","volume":"12 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142191183","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 series of the circulation indices and ERA5 and ERA5-Land reanalysis data were used. The contribution of the general circulation modes, sea surface temperature, and air temperature to the changes in heat and moisture fluxes on Russian plain territories can vary from 40 to 90% depending on a landscape zone. The vertical fluxes of heat and moisture in European Russia and Western Siberia are largely dependent on the SCAND and EA/WR regional modes of atmospheric circulation. With a change in the phases of SCAND and EA/WR from positive to negative, a significant increase in the areas of influence of these modes on heat fluxes occurred in subarctic and boreal landscapes, and a decrease in the areas of influence on moisture divergence was registered in boreal and subboreal landscapes. In the summers of 1950–2021, trends in upward sensible heat fluxes were evident in subboreal landscapes of eastern European Russia (4–6%/10 years). The trends in upward latent heat fluxes in subarctic and boreal landscapes of Western Siberia were about 3%, and the ones in downward latent heat fluxes in subboreal landscapes made up about 5%.

These radar measurements, however, need to be calibrated for more accurate rainfall estimation. This article introduces a new calibration approach using time-stepwise processing of reflectivity–rainfall rate (<span>(Z{-}R)</span>) relationship. Based on the previous work utilizing the radar–rainfall relationship, this article hypothesizes that the rainfall measurement from a ground based radar are affected by the distance from radar, altitudes and rainfall time duration. Unipolar ground-based radar data sets for two consecutive years with 77 occurrences of rainfall from 39 stations in calibration window of three hours as well as the corresponding rainfall measured from registered rain gauges were used in this study. The results indicated that it is better to use the radar–rainfall relationship <span>(Z=aR^{b})</span> in view of the altitude effect (<span>(H)</span>) and empirical coefficient (<span>(c)</span>), such that <span>(Z=aR^{b}H^{c})</span>. The changes in the distance from the radar and duration of precipitation were evidently significant. For radar–rainfall relationship individually, the values of the determination coefficient <span>(R^{2})</span> made up from 0.88 to 0.97, and those for this relationship in view of the altitude effect (<span>(H)</span>) were from 0.70 to 0.97. It is therefore concluded that the use of other effective parameters (distance from radar, altitude and rainfall time duration) leads to optimum accuracy of the <span>(Z{-}R)</span> relationship.</p>","PeriodicalId":49581,"journal":{"name":"Russian Meteorology and Hydrology","volume":"11 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142191188","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}

For the first time, the predominant soil type under winter wheat within the district and the corresponding soil characteristics have been determined as input data for the Climate–Soil–Yield system using the digital version of the Soil Map of the Russian Federation (1988). The estimated recourses for providing the wheat production with water and mineral nutrition for 2010–2020 range from 40 to 69% in the Millerovo district and from 73 to 85% in the Zernograd district. In the years with a relatively small yield potential, the level of mineral nutrition resources is high, which is caused by a decrease in the nutrient limitation effect, since radiation and thermal factors limit the maximum biomass and, consequently, the maximum uptake of nutrients by crops.
