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

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.

Estimation of Frequency Response of Earth’s Climate System to External Radiative Forcing

 We consider the Earth’s climate system (ECS) as a linear system whose output is the global mean temperature anomaly DТ(t). The input the system, along with changes in the solar constant DI(t), can be affected by other factors, and at the output manifest themselves own temperature fluctuations and a random noise. The spectral analysis of the data shows the existence of statistically significant coherence between DI(t) and DТ(t).

Ethnic Aspects of Urbanisation in Saratov Region

Saratov region is one of the most highly urbanized Russian regions. Despite a significant percent of medium and small cities (83.3%), only 34% of the regional urban population live their. Due to the nature of the ethnic composition of the population, external migration, as well as to demographic behavior of different peoples, ethnic composition of the population of the region, and cities in particular, is changing.

On the Influence of the Planetary Front High-Rise Zone to Change Some Characteristics of the Climatic Regime in the Northern Hemisphere

This article considers the questions of influence of the planetary highrise frontal zones (PVFS) on the climatic regime of the Northern hemisphere. Shows the dynamics of the areas PVFS relatively natural climatic periods state the earth’s climate system. The connection of the speakers areas PVFS with the wind regime change in the hemisphere

The article is devoted questions of regional and local level geosystems landscape mapping with Saratov region’s right bank as an example. Mapping was organized with GIS technologies using on the basis of topographic and thematic maps and space images decoding

Historical and Methodological Aspects of the Application of Landscape-hydrological Analysis in the Study of Geosystems

In this article the analysis, generalization and systematization of materials of hydrological researches of Russian and foreign scientists are carried out to the period since the end of the nineteenth century till the present time. The extent of the investigation of the problem of application of landscape- hydrological analysis in the study of geosystems is revealed; the various approaches and methods are considered

Geoecological Situation in Saratov and its Possible Impact on Cancer Incidence Population

The article deals with geoecological situation in Saratov in the first decade of the new century. Also in the article was estimated air pollution in the most dangerous pollutants, particularly affecting on cancer morbidity such as dust of different origin, formaldehyde, benzo (apirenom) phenol. Identification and localization of zones and areas with adverse environmental conditions is necessary for more rigorous, including screening observations on the development of the carcinogenic situation and correcting regional cancer program
