Conditions of аutumn Vegetation and Wintering of Winter Crops in Saratov Region

Authors: Pryakhina S. I., Sklyarov Y. A., Vasilieva M. Y., Fridman Y. N.

The analysis of meteorological data obtained daily for 67 years was made to select the criteria for evaluation of hardiness and wintering of winter crops. The highest repetition frequency of disadvantageous winters was observed in 1960-s. The increase of temperature and precipitation during the winter in the past thirty years has created advantageous conditions for cultivation of winter crops in Saratov Region. 

Features Synoptic and Agro-meteorological Conditions of the Autumn Period in 2016 in the Lower Volga Region and their Impact on the Autumn Growing Season of Winter Crops

Authors: Ivanova G. F., Levitskaya N. G., Demakina I. I.

The article presents an analysis of the synoptic and agrometeorological conditions prevailing in the region in the autumn of 2016. Shown anomaly hydrothermal regime and assessed the impact of the prevailing conditions at the seeding, the autumn vegetation and tempering of winter crops.

Meteorological Features During Summer 2015 in Saratov

Authors: Lapina S. N.

The characteristics weather conditions and circulation processes during summer 2015 in Saratov are discussed. Their role in the formation of precipitation is estimated.

Sinoptical and Agrometeorological Conditions Anomalous Weather of the Autumn-winter Season 2015-2016 Year in the Saratov Region

Authors: Ivanova G. F., Levitskaya N. G.

The article provides an analysis of sinoptical conditions that caused the abnormal weather of autumn and winter 2015–2016 year in the Saratov region. The characteristic agrometeorological conditions in different soil-climatic zones of the region, showing the deviation of the air temperature and precipitation from the climatic norm and the assessment of their impact on growth, development, and overwintering of winter crops.

Research of Characteristics of Humidity Regime of Atmosphere in the Conditions of Changing Climate of Saratov Area

Authors: Ivanova G. F., Levitskaya N. G., Demakina I. I.

In the article the tendencies of change of relative humidity and deficit of humidity of air, numbers of days are shown with relative humidity of air ≤of 30% and ≥80%, number of dry and moist days, to maximal duration of dry and moist periods during the vegetation of agricultural cultures, and also monthly and annual rainfalls and number of days with the different amount of fallouts. Speed over and meaningfulness of these changes are brought in a period from 1981 to 2014 on the station Saratov South-East.

Changeability of Maximally Possible and Total Evaporation on Territory of Saratov Area in the Conditions of Changing Climate

Authors: Ivanova G. F., Levitskaya N. G.

To the article the estimation of dynamic of annual precipitation is driven, maximally possible and total evaporation in the different soil-climatic zones of the Saratov area in the conditions of the global warming of climate. It is shown that in a period from 1981 to 2014 year noted a statistically significant increase in the maximum possible evaporation, which leads to an increase of deficit of evaporation. As a result of the observed tendencies the climate norms of gidromelioration in the area were increased on 200–300 м3 / hectare.

Characterization of Anomalous Precipitation and their Genesis in June 2013 and 2014 in Saratov

Authors: Lapina S. N.

Circulation processes during the formation of anomalous precipitation in June 2013 аnd 2014, which identified a high yield of grain crops in the Saratov region, are analyzed.

Changes in Annual Precipitation Structure and Soil Water Regime in the Saratov Region

Authors: Ivanova G. F., Levitskaya N. G.

The paper shows the changes in precipitation regimes in their annual cycle on natural areas of the Saratov region during the observation period from 1936 to 2012. The decrease in precipitation in the main vegetation period leads to increase the aridity, especially significant in the forest-steppe areas of the region.

Influence of Extreme Displays of Climatic Changes on Efficiency of Agricultural Crops

Authors: Ivanova G. F., Levitskaya N. G., Shatalova O. V.

Repeatability and dynamics of probability of various type of droughts, and also estimation of their intensity on hydrothermal factor for the 120-year-old period (1891–2010гг is shown.). The agrometeorological characteristic of the most severe droughts is given. Decrease in productivity of grain crops and total gathering of grain in the Saratov area in years with various types of droughts is resulted

Variability of Climatic Rates for Period of Instrumental Observations in Saratov

Authors: Ivanova G. F., Levitskaya N. G., Orlova I. A.

On the basis of a long series of observations (1912–2010 gg.) investigated long-term variability in temperature, precipitation and other meteorological parameters. It is shown that climate normal of temperature and precipitation in the modern period is significantly different from the baseline period of 1961–1990 gg., proposed by the WMO
