Possibilities of geoecological risk-analysis methods for Saratov region Protected Areas network are considered. Natural features and geoecological risk factors of Cretaceous slope with calciphilous plants near Volsk city Protected Area are discovered

In this article considers the nature of the atmospheric circulation in the atlantic-eurasian sector of the hemisphere with the use of multiyear averages maps of the surface of the AT-500 Hpa, corresponding to different periods of state of the climate system (stabilization, the second wave of the global warming). On the basis of the dynamics of change of temperature fields on the average level of the troposphere conclusion is made about the forthcoming changes of winter conditions on the Russian plain

The article is on the daily weather data for the seventy-year period (1941–2010 гг.). The evaluation is given on the winter season according to the rate of the favorable wintering of the winter crops. The analysis showed that the wintering period has shortened over the period of the last three decades and the percentage of loss of winter crops has decreased

Features of origin and evolution of a stationary anti-cyclone which caused cold weather in all European territory of Russia in the winter of 2012 are considered. Abnormal values of temperature and pressure are considered on an example of Saratov

Restoration of the impulse response of the Earth's climate system (ECS) showed that the rate of its reaction can be characterized by an equivalent time constant of 1.04±0.17 months. Sensitivity of ECS to changes in radiative forcing is equal to 0.41±0.05 K W^-1m², which gives the positive feedback factor 1.37±0.17.

The article represents concept definition of “Saratov Privolzhie” as a geotoria 60 km wide and including right and left Volga bank territories and Volgograd and Saratov storage pounds water area. This is the most economic completed but also recreation important part of Saratov region. Landscape structure of Saratov right bank of Privolzhie  (Predvolzhie) is considered up to the level of landscape locality.

There are considered the basic weather- and climate forcing of synoptic processes in the Lower Volga region. Below shows the dynamics of their changes on a background of global climate trends. It is shown that the cold temperature of the winter months is formed under the influence of the arctic anticyclone. Of the cyclones on the arctic front and of the cyclones on the polar front are formed warmer winter weather conditions

Unique features of relief of the territory of Saratov are considered in this article. The characteristic of the spatial connection of identified system of block morphostructures is given. The assumptions about the main relief forming factors are made, assessments of the development intensity of geologo-geomorphological processes and connection of natural-technogenic phenomena with them is given

Structure of Volga flood plain landscape at Saratov area before Volgograd storage pound building is defined in the article. Changes in flood plain geosystems after regulated river are considered, directions of modern landscape generating processes against the background of large-scale anthropogenic transformation are detected

The forecast of the spring wheat quality is represented in this work summer wheat, barley, oat and winter wheat. The forecast is composed on the grounds of correlation of the amount of protein in cereal with monthly air temperature in June. The education derived by the authors lets to estimate the cereals quality in monthly advance. The forecast of the new harvest cereal composed in advance has an important meaning in organisation of cereal provision
