Heavy dust storms within the area of eolian morphogenesis in Eurasia and orientation of eolian mineral flows are related to formation of Asian anticyclone and its influence on atmosphere. Its centre is moving from Middle and Lower Volga, Western Kazakhstan to Altai-Sayan Mountains and Northern and Central Mongolia. Formation of cyclonic whirlwinds by its periphery determines the formation of storms, hurricanes and strong blowing dust. These processes are especially strong during early spring (March-April) when contrasts of temperatures are maximal and cyclonic activity is most intensive at the polar front. When center of anticyclone is over Central Mongolia and cyclone is over the Yellow Sea and Korea eolian processes are extremely strong; in such case there happen severe dust storms in the areas of air currents convergence over the eastern Goby, plateau Ordos, and Loess plateau.
The new typification of river valleys is put forward, wherein the morphological types of river valleys are determined by riverbed processes, shaping these valleys. Thus a possibility arises of combination of river valleys` typification and riverbeds classification (according to R.S. Chalov), and, consequently, of compiling the integrated characteristics of riverbeds and river valleys in general. There are the river valleys without flood-plain and with narrow ones with incised riverbeds, box-shape and U-shape valleys with adapted riverbeds, and terraced valleys with wide floodplains.
