Variations of existing glaciers in the Southwestern mountain region of Xizang (Tibet)
The SW-mountain region of Xizang in this paper is taken to extend between 27° 10′ – 30° 10′N / 84° 50′–91° 30′ E, that is the vast area stretching from the Himalayas to the South Range of Xizang. The author has been in the area many times over 20 years surveying and conducting scientific investigations. In 1984 the author took part in the Sino-German Joint Expedition for further survey and the interpretation of aerial photographs and satellite images of the same area. The paper presents the data collected during this period.
Fluctuations of Glaciers from 1970 to 1978 in the Khumbu Himal, East Nepal:Glaciological Expedition of Nepal, Contribution No. 72.
As a part of the Glaciological Expedition of Nepal (GEN), the fluctuations of the glacier termini of 15 glaciers were measured in the Dudh Kosi region, east Nepal, from 1970 to 1978. According to the fluctuation rate, the glaciers are classified into four groups; retreating (8 glaciers), stationary (3 glaciers), advancing (3 glaciers) and irregular (1 glacier). Many glaciers have been retreating in recent years. The retreating glaciers have gentle inclinations of less than 20°, no crevasses developed near the termini and the gentle terminal ice cliffs, while the advancing glaciers have steep inclinations of more than 20° and well-developed crevasses exist near the termini and steep cliff-like termini. The distributions of the present moraine also indicate that there is a receding trend with intermittent small scale advances during recent decades. The recent trend toward glacier retreat in this region can be thought as a link in the long-term receding trend since the 16th century.
Synthesis of quasi-stationary inhomogeneous impedance body of arbitrary shape
Formulas were obtained for the reflection factors of a plane wave from the inhomogeneous impedance plane, which reflects the incident wave in the given direction. The problem of synthesis of impedance inhomogeneous rotation body was solved for an arbitrary shaped generatrix for the given scattering diagram for co- and cross polarizations. Impedance distributions were obtained in explicit form. Restrictions on the class of implementable scat- terplots were formulated.
