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.

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.

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.

Authors: Pryakhina S. I., Guzhova E. I., Smirnova M. M.

This article touches upon daily urgent factfiles during the 30-year period. The author of the article calculates all famous in literature criteria of drought. But no one of them reflects a degree of a strong drought when more than 70% of crop dies. The author introduces first the physiological coefficient of drought

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
