Über dieses Buch

This book highlights the aeolian processes in the desert zone of Kazakhstan and analyzes the current status of dust and sand storms in Central Asia and Kazakhstan. It also highlights the analyses, dynamics and long-term observations of storms on the basis of numerous cartographic materials and satellite images. Dust/sand storms are a common and important phenomenon in the arid and semi-arid regions of Kazakhstan, especially in its southern parts, where areas are covered by a great variety of deserts and offer a significant source of mineral and salt aerosols. The deserts of Kazakhstan mostly cover lowlands and extend from the eastern coast of the Caspian Sea to the piedmonts of the Tien-Shan Mountain. In Kazakhstan, desertification processes due to wind erosion in the form of dust/sand storms were observed in semi-desert and desert landscapes.

Chapter 1. Introduction and Status of Storms in Central Asia and their Environmental Problems

Abstract
Dust and sand storms are common events in the arid and semi-arid regions of Central Asia and Kazakhstan. In the Central Asian countries the main scientific observations on dust and sand storms were performed mainly before 1980 during the former Soviet Union. Regular monitoring of dust and sand storms began 1930s at a large number of observation sites located over the entire territory of Central Asia. The first studies and results of research regarding the analysis of dust and sand storm in terms of observations were published during the 1960s.

Chapter 2. Natural Conditions of Central Asia and Land-Cover Changes

Abstract
More than 40% (or more than three quarters) of the territory of Central Asia is desert lowland, which varies greatly in configuration as sandy, stony, salt, and clay deserts (Lewis 2003). The deserts of Central Asia expand from the shores of the Caspian Sea in the west up to the foothills of Alatau Mountain (Tianshan) and Pamir-Alay to the east and southeast. This wide territory is represented by a great variety of desert types.

Chapter 3. Spatial and Temporal Distribution of Storms in Central Asia and Kazakhstan

Abstract
Due to the vast and diverse desert types across Central Asia and Kazakhstan, dust storms vary by frequency, duration, and intensity.

Chapter 4. Relationship Between Storms and Land Degradation

Abstract
Almost all major sources of dust and sand storms are located over topographical lows or on lands adjacent to strong topographical highs where fluvial action is evident by the presence of ephemeral rivers and streams, alluvial fans, playas, and saline lakes.

Chapter 5. Dust Storms in Central Asia and Kazakhstan: Regional Division, Frequency and Seasonal Distribution

Abstract
Dust and sand storms are common events in the arid and semi-arid regions of Kazakhstan. According to observations by meteorological stations, high wind-speed regime, scarcity of vegetation cover, frequency of soil and atmospheric droughts, and the continental climate of Kazakhstan, all of which promote the development of dust storms, are typical for Kazakhstan almost all over the territory of the republic.

Chapter 6. Aeolian Transport of Dust and Sand in the Deserts of Kazakhstan

Abstract
Sand and dust storms are complex natural phenomena. During storms, transported sand and dust particles can be observed in a thin sub-surface air layer or even through the whole atmospheric boundary layer. Thus, vertical scales of the phenomenon can change from small fractions of 1 m to ≥1 m high.

Chapter 7. Conclusions

Abstract
Dust and sand storms are common phenomena in the arid and semi-arid regions of Central Asia. Climatic conditions (small amounts of atmospheric precipitation, high temperature, and strong winds), huge areas of sandy, clayey, and solonchak deserts, and scarcity and poorness of vegetation cover all cause dust and sand storms.
