ABSTRACT: This article is a review of investigations at the Vysolzogornyy Geophysical
Institute (Vysokogoinyy geofizicheskiy institut) concerning processes of the formation of
rain and hail, performed between 1956 and 1963. An analysis of the data showed that at
the initial stage of development of the convective cloud, the rise of air masses is accom-
plished as individual thermals. Upon farther development of the cloud the number of
thermals. increases, they merge in the central part, forming an updraft. In large convec-
tive clouds, beginning approximately from the cloud base, the velocity of the updraft in-
i creases almost linearly with height and reaches a maximal value at about the middle part
of the cloud, after which, toward the top of the cloud, the velocity again begins to decrease,
also linearly. The maximal value of the updraft velocity is reached in the camulus-rain

stage of the development of the cloud and amounts to 25-30 m/sec. The appearance of
descending motions in the cloud is associated with the start of precipitation. With the
course of time the updrafts are replaced by downdrafts. The change in time of the velocity,
---i of the updrafts at the period of maximal development of the cloud Is insignificant. On
examining the process of the formation of showers falling from convective clouds, a calcu-'
lation of the change of velocity of the updraft with respect to height led to qualitatively new
results. It became possible to explain such important characteristics of the process of
the formation and precipitation -as the brevity and great intensity of the showers, rainfall
from warm clouds, the role of giant crystallization nuclei in the formation of showers, etc.
These factors were not fully satisfactorily explained by existing theories. The formation
I Of showers is associated with the coagulation growth of individual large drops formed on
giant condensation nuclei. Radar investigations of the process of the formation and falling
of showers and hail show that the zone of hail growth Is situated in the front of the cloud
and usually occupies a much smaller volume than the volume of the cloud itself. The
authors describe a method which permits, on the basis of aerial synoptic data, to deter-
mine the presence in the atmosphere of favorable conditions for the formation of large con-
vective clouds and the accumulation of large reserves of supercooled moisture needed for
the formation and growth of hailstones. The possibility of the accumulation of moisture in
a cloud in a supercooled form is determined by the magnitude and character of the energy
distribution of vertical atmospheric instability. The changes of stratification of the atmos-

falling from the level of the zero Isotherm to the earth's surface are taken Into account
when forecasting hail processes. The method of forecasting hail phenomena was checked
under field conditions to prevent hail damage and the method proved to be quite. reliable.

ABSTRACT: The results of radar investigation of zones of reflections from hail and
rain clouds are cited. The investigations were made in the northern Caucasus bet-
w_eei~_I~_66_and 1964. The results of the investigations are used to suggest methods
for determining the hail content of a cloud, the site of hail origin in the cloud,
methods for evaluating hail size and the type of precipitation which will reach the
earth's surface, taking into consideration the molting of hail stones below the zero
isotherm. Orig. art. has: 11 formulas, 6 tables, 8 figures and a bibliography of
29 titles.

perimental studies of the process of formation and precipitation of from convection
'clouds., as well as new ideas on the mechanics of hail formation in convection clouds
Mthods are shown for radar detection of hail centers and the determination of the
size of hail vitMn conrection clouds. The book gives the method of control of hail
processes developed from 1960-1962 and used in 1963 for the protection of agricul-
tural crops against damagee by hail, The results of these studies are given as 'well
as an out Lime of their organIzation.

ABSTRACT: The author describes in detail the Permian and Triassic
deposits, which reach a thickness of 700 m in the Dnepr-
Donets basin. Up till 1951 these de osits were called
the "variegated Permo-Triassic beds. The Permian rocks
are divided into 'three formations: 1) argillaceous-
calcareous-anhydrite, 2) argillaceous-silty, and 3)
sandy-conglomeratic. The first and second formations
are Lower Permian; the third is Upper Permian. These
Card 1/3 rocks were described in detail in an earlier paper by

the author (Lapehik, F. E., Geologichniy zh., 1954, Vol 14, Nr 3).
The Triassic deposits are divided into four. formations (from the base
upward): 1) sandy-carbonate, 2) argillaceous red beds, 3) sandy,
and 4) argillaceous. the first, resting on an erosion surface on
Permian rocks~ and containing conglomerate at the base, is uniform
in composition and has a thickness of 20 m to 40 m. Only in the
region,lof Domanovichi, in the central part of the depression, is it
apparently ~epl-aced by variegated clays with layers of siltstone,
having a total thickness of 80 m. The sandy-carbonate formation
grades into the argillace& us red beds, the thickness of which is 150
m to 190 m in the central part of the basin, but which decreases to
85 m at the borders and on the Romenskaya structura (structure).
The overlying sandy formation is rather persistent along the strike,
but variable in thickness (9 m to 25 m). The upper very character-
istic argillaceous formation ranges up to 190 m in thickness in the
central parts of the basin, but at the borders it is but 30 m. It
is unconformably overlain by Jurassic deposits. These characteristic
formations,, representing two sedimentational cycles, are referred by
the-author to the Lower Triassico but or, his accompanying diagram

fiBSTRACT: A careful study of the minerology of the Permian and
Triassic rocks of the 1-: i)nepr-Donets Basin, with con-
sideration of fossil data and electric logs, has made
it possible to divide them into a number of series and
horizons. The Permian rocks are characterized, on the
whole, by the high conbent (up to 50 to 90 percent) of
black or minerals in the heavy mineral fraction. In
addition, minerals that are invariably present are leu-
Card 1/2 coxene, iron hydroxides (goethite 'and limonite), garnet,

zircon, and others. Besides strongly weathered feldspars, the
light fraction is characterized by well-rounded fragments of
siliceous quartz-mica, and clay shales, of quartzites, and of
highly altered (effusive?) rocks. The Triassic rocks have a
typically high content of garnet, which is generally more abun-
dant than zircon. Epidote and ilmenite are present in many
places. In comparison with the Permian rocks, the Triassic
deposits are marked by a complete absence or by an insignifi-
cantly small quantity of leucoxene. In both Permian and Trias-
sic rocks, authigenic minerals observed are calcite, limonite,
pyrite, and barite. Of these, limonite is the most abundant
in the Upper Permian and the Upper Triassic deposits. The
Lower Permian rocks are characterized by sulfates (anhydrite,
gypsum, barite, and celestite) and carbonate (dolomite and
calcite), which commonly occur as rock-forming minerals. A
Table is given in the paper, showing the mineral associations
in the series and horizons of the Permian and Triassic rocks
of the region.
