and anticyclones; these problems are still unsolved, despite the
abundance of theoretcial and empirical data. One of these problems
is the effect of thermobaric field structures on the origin of the
cyclone and anticyclone', and also on the process of cooling and
warming air by advection. The author analyzes the results of 110
observed cyclones and 82 anticyclones and discusses: (1) The
geostrophic wind velocity along the Isobaric levels of 700, 500,
and 300 millibars and the horizontal temperature gradients at
the 500 millibar level in the area of cyclones and anticyclones
over theocentral, cold, and warm sections; (2) the advection
of vortices at 700,500,and 300 mb isobaric levels and advective
changes of temperature in the 500-1000 mb*layers over the central
section of cyclones and anticyclones; (3) the changes in the
turbulent air movement and their dependence on elevation in the
near-surface layer of the cyclonic area; (4) the changes in the
mean temperature at 500-1000, 300-500, and 200-300 mb levels in
the process of development of cyclones and anticyclones; andfillaj-
ly (5) the changes in baric,pressures observed during a 12-hour
interval. All the points casidered may facilitate forecasting.

Tomashevich, L.M. Cyclone Regeneration and the Effects of
Vertical Currents on Thermobaric Field 56
The author analyzes the process and the effect of the
penetration of air massea,mostly of cold air, Into a
cyclone area; such an injection (intrusion) represents a
new source of energy capable of reviving a dying cyclone.
The regeneration of a cyclone is linked with the deepening
of the cyclone area; new fronts are created, the upward
movement is intensified, the former direction of the cyclone
movement 'is changed, and the precipitation is increased.
Since a regenerated cyclone causes considerable shift in
the prevailing weather conditions, these conditions can be
predicted from some of the symptoms of the regeneration occurring.
The author explains the nature of the regenerated cyclone and
describes the principal changes which occur atX700 (absolute
topography at 700 millibar level). The explanation is theoretical

and is based on the selected coefficients of vorticity; in this
connection, reference is made to V.A. Bugayev who worked out a
mathematical solution of the problem of vorticity. Statistical
data are derived from observations conducted between 1947 and 1951-
Two pages of the author's own conclusions contain data on the
distribution of velocities for primary and regenerated cyclones in
various stages of their development and on the accompanying
temperature behavior. The essential indications for the regeneration
of a cyclone are given. There are 11 drawings, 5 tables, and 8
Soviet references.
Leonov, N.G. Cyclone Displacements Due to the Structure of
the Baric Field in the Atmosphere 82
The author examines the rule of the leading jet in predicting
the possible direction of a cyclone. This rule implies that
cyclones move at 700-500 millibar levels with the direction
of the wind above the cyclone area. However, since information
on such winds is difficult to obtain' the author discusses and
evaluates the possibility of using the data on the geostrophic

wind present over cyclonic areas. The author arrives at the
conclusion that displacements of cyclones are affected by
factors other than the winds alone. There are 29 tables,
3 figurets, and no references.
Shishkova, I.A. Methods of Calculating Local Accelerations
The author reviews the problem of deviation of local winds
from the geostrophic wind and offers an empirical rule for
determining the direction of any such deviation through an
analysis of local accelerations. Of particular importance
in such cases is whether or not the wind in question deviates
toward a low pressure or a high pressure area and at what
velocity it moves. The mathematical solution, suggested by
the author, results in 76-78 percent correct predicitions as
to the direction of the wind. The author concludes that no
connection exists between variations in the velocity of the
wind and the direction it takes. An increase (or decrease) in
wind intensity within 12 hours can occur with deviations toward
either the high or low pressure areas. There are 2 figures and
3 Soviet references.

Glazova, O.P. Determination of Maximum Daily Air Temperature
by Vertical Sounding of the Atmosphere 120
The author recapitulates the standard method of evaluting
the radiation balance for the interval of time between sunrise
and the moment of maximum daily temperature, including the
determination of the latter. Reference is made to the efforts
of N.I. Bel'skiy and Ye. Golld which were directed to this
end. The American meteorologist T. Williams is also mentioned
in this connection, but his technique is rejected as not
applicable to conditions in the European USSR. Bellskiy's
version 1;3 accepted by the author and explained in detail.
Elaborati-,.119 on Bellskiy's method, the author of the article
considers the following meteorological factors essential for
the determination of maximum temperature: the flow of solar
radiation, the dynamic turbulence, and the horizontal displacement of the
air caiised by the temperature gradient. The mathematical
method reduces to defining the value of what is called by the
author "an elementary square,11 a quadrangle enclosed between
isobars W-th a 10 mb spread and isotherms 10 apart. This area

correspcnds to the amount of heat (2.45 calories) required
to raise the temperature of an air column 10 C, the column
having a cross section of 1 cm2 and a height corresponding to
a pressure difference of 10 mb. The weight of the air column
is 10.2 grams and its specific heat 0.24. The article examines
also the role of dynamic turbulence in changing the air temperature
in the near-surface layer (i.e. 3oo-4oo meters), when there is
no advection. There are 3 tables, 3 figures, and 6 references,
of which 4 are Soviet and 2 English.

ABSTRACT: The conditions at the surface of the earth in the antarctic
are very strange4 They are described* Data obtained from
pilot balloons of the Mirnyy and Mauson stations are taken
as a basis. The data on the number of investigated observa-
tions are given in Table 1. The recurrence in ~ of the east
and west wind components at various altitudes and in various
months are given in Table 2. On the strength of these facts
the author arrives at the following conclusions: 1) In the
majority of oases at the east coast of the antarctic in the
lower strata an east wind component is found. This proves
the assumption that as a rule a high pressure field exists
above the antarctic. 2) The recurrence of the east oomponent

one increases. Beginning with an altitude of from 3 - 6 km
the range of lower pressure dominates. 3) The seasonal cha-
racteristics of the changing over from an anticydl-onic cir-
culation to a cyolonio circulation are described- 4) The
changing over from a summer type of circulation to an autilmn
type takes place sufticibntly abrupt and jump-like. Either
the activity of ozone in the respective stratum is suddenly
decreased or the active ozone stratum is shifted in the direc-
tion towards the ocean. 5) Cases occur all over the year
where the area of high pressure above the antarctic covers
the whole troposphere. In winter this ocoura relatively
rarely, in summer more frequently. 6) During the major part
of the year, except stimmerg the antarctic anticyclone is
with respect to the altitude not so well developed in the
area of 11auson than is the case in the area of Mirnyy- 7) The
activity of the ozone stratum in the area of Mauson is more
marked than at Mirnvy. There are 2 tables.

TITLE: Meridional Transfer in the Areas of Mirnyy and Mauson
(Meridionallnyy perenos v rayonakh Mirnogo i Mausona)
PERIODICAL: Meteorologiya i gidrologiya, 1959, Nr 6, PP 15 - 1'9 (USSR)
ABSTRACT: To clarify the characteristics of the meridional transfer above
the east coast of the Antarctic country, the data obtained in
sounding the atmosphere in lAirnyy and Mauson with respect to
the wind during the Ist continental Antarctic Expedition (from
March 1956 to February 1957) were analyzed here. On the
.basis
.
of this analysis, the following facts could be ascertained: 1)
In the troposphere, the direction of the meridional transfer is
different in MirnyyandinMauson: the northern transfer prevails
in Mirnyy, the southern one in Mauson. 2) In the stratosphere,
the northern transfer prevails in the areas of Mirnyy and
Mauson. This prevailing becomes more distinct with an increas-
ing altitude. 3) The zonal component of the horizontal tempera-
ture gradient in the area of Mirnyy is directed in the tropo-,
sphere on an average from east to west, and in the stratosphere-
from west to east* In the area of Mauson, this component is di-
Card 1/2 rected from east to west both in the troposphere and in the

Meridional Transfer in the Areas of Mirnyy and Mauson SOV/50-59-8-4/19
stratosphere. 4) On the coast of the eastern Antarctic, near
the meridian of Mirnyy, the stationing of cyclones, which shift
along the southern Indian Ocean, often takes place. 5) In win-
ter, the shifting of cyclones takes place above the southern
Indian Ocean, normally with a large meridional (southern) com-
ponent. In spring, a zonal shifting of cyclones from west to
east is mostly observed near the coast of the Antarctic country.

ABSTRACT: Modern concepts on the tectonics, geological structure and formation
time of the Caspian lowland are presented. The changes in reservoir properties of
pre-kungur rocks are examined. The reason for seismic prospecting done by the
reflected wavo method and by the refracted wave method is explained. An SS-30/60
seirmic station was used. The reflected seismic prospecting followed the single
proilling systiem from one point of the explosion. The explosion spacing was 450 m,

for prolonged 900 m travel tile curves, and in this case 2 explosion points were
used. Groupti of 3 seismographs per channel with parallel connection were used.
The grouping base was 30 m, the distance between group centers was 15 m. The
depth of the explosion In blue clay was 18-32 m; in quicksand it was 15-10 m; in
Allian-Senaman sands on the dome caps it was 50-125 m. 'Me average change was
13 kg. The working filtration was 45-60 cps. When registering quality deteriorat-
ed, the distance between the group centers was established at 7. 5 m. During the
refracted wave survey, the length of the travel time curves being 2. 4-3. 6 Ian,
observations were carried out from 3-4 points of the explosion with 1. 2-1. 8 km
between point. The working filtration was 0-25 cps and the average charge was
43 kg. Construction of the cuts was made by the to methods, Intersections, and
"time fields"., A detailed gravimetric survey was made simultaneously with two
GAK-ZM gra:vimeters at a 450 m spacings. The mean square error of observations
was 0. 2 mgal. As a result of the seismic survey, conditional horizons, found to be
identical with. the base of the kungur formation and the Upper Carbon were defined.
The horizons lie following an interval of 1200-1400 m, and dip west towards the
center of the lowland, from 2.0-3. 0, to 6.0-6.5 km. On the average, kungur
horizons dip at an angle of 3 to 5 degrees with local layer flexures of a 300-400 m
range (under the domes of Itasay 2. Oktyabrskiy, Kindysay, etc.). In the center
of the Caspian lowland, subealt reflections are traced under domes, but at the

eastern margin of the lowland, they are traced only in the regions of intordome
areas. The author explains this phenomenon by the homogeneous composition of
salt nuclei in. the center of the lowland and the presence of rewaBhed continental
deposits on the periphery. Regional studies have shown that subsalt deposits on the
eastern margin of the Caspian lowland lie at depths which can be reached by drilling.
The need to combine gravimetric survey and high precision surface magne tic survey
with seismic survey is Wicated. 1. Mokeyev. [Translation of abstract] [GC]

TEXT: The application of the method of the point transformations
to the investigation of dynamic systems sometimes necessitates
investigation of a discontinuous transformation of a straight
line into a straight line, Such a problem can be encountered
in the synchronisation of a multivibrator by a periodic train
of pulses (Ref. 3). In the following it is assumed that the
transformation has one discontinuity and it is described bya
X x = ~Tlx = a + Xlx (x < 0)

In the author's earlier works (Refs. 1, 2) the cases when
the n -transformation had no simple fixed points or had only
simple fixed points were investigated for a~ 0 and b < 0
The remaining cafes (I) ab> 0 and (II) a < 0, b> 0

ABSTRACT: The author considers the simplest type of self-oscillating optimalizing control
ksystem. (with & one-dimenBlonal controlled element). The control object is made up of an
inertialess nonlinear link and an aperiodic link of the first order cc-anected in series. The,
equations of motion for the system are:
(1) .,q($ -0), .1 al~ + pli
d)L>0, a,-- _Alor_'~U-,& > 0., a, A,
where o( 1, 191, and 4 are positive parameters. Previous studies have shown that when
0 there is a region among the states of the system where there is no sen-r6 for an

extremurn at the output of the control object (i.e., the input of the object does not varl). This
may cause search instability in real systems. Men c< I = 0, a region of nondirectional
search appears (i.e., for any state of the system within this region the Input of the con-
trolled element may either increase or decrease) which lowers the quality of the optimalizing
search process at the output of the controlled element. In this paper It is shown that these
disadvantages are practically eliminated when o( I = Pi - It is also shown that there Is a
unique stable periodic operating regime for the system. An explanation is given of the
relationship between the parameters of the system and the average operating conditions for
the period when the output of the control object deviates from the extreminn. Orig. art.
