The recording accuracy is of the_2rder of magni- tude of I cm/sec for the wind velocity and 10 degrees C-lor the temperature; the time element is recorded to within i0 sec. (This degree of time .i.naccuracy leads to a leveling of any variations in the velocity and temperature distribution on a scale of the order of 5 cm for a wind velocity of 3 m/sec. ) The instrumentation is based on the principle of the hot-wire Card 1 /3 anemometer; the probes employ thin platinum wires (20 diam) 124-58-9-1005"' Methodology for the Measurement of the Microfluctuations (cont. .) During wind-velocity measurement the filament is heated to 200- 300'C by the passing of a current (of the order of 0. 2-0. 25 amp). Temperature changes (and, consequently, resistance changes) occurring in the filanient are go%crned by its heat rejection to the air, which depends on the wind-velocity component normal to the filarnent and is virtually independent of moderate air-temperature variations (of the order of magnitude of I degree C). Therefore, a meaSUre- ment of the resistance of the filament yields a detern-iination of tile wind-veloc- ity component normal to it; an inconvenience therein arises through the non- linear character of the relationship betweed the resistance and the wind veloc- ity. The resistance measurement is performed by means of a Wheatstone bridge, so that (with the aid of a galvanometer and a loop oscillograph) the current inten.,iity in the diagonal of the bridge can be measured directly. The bot-wire anemometer can be planned for the measurement of the horizontal wind-velocity component (with a probe having a vertically positioned filament) or of the difference between the horizontal components at two points of the flow (two probes are plugged into the arms of a Kelvin double bridge, so that both tile sum and difference of their resistances can be recorded simultane- ously), The measurement of the vertical wind-velocity component is rendered possible by an "angular adapter", which consists of two filaments positioned in a vertical plane at angles of +450 and -450 relative to the direction of the Card 2/3 124-58-9-10052 Methodology for the Measurement of the Microfluctuations (cont. ) mean wind. The difference between the resistances of these two fil aments is approximately proportional to the vertical wind-velocity con-1ponent (wherein the ratio factor is a function of the resultant wind velocity. In the micro- thermometer element the current passing through its fiLiment is of low inten- sitv ('of the order of I ma*), so that the overheating of the filament relative to the surrounding air does not exceed 0. OIOC. Therefore, the temperature (and, hence, the resistance) of the filament depends upon the air-temperature fluctuations and is virtually independent of the wind velocity. The resi~.tancv is also measured by mean_~, of a Wheat!:tone bridge, and it is found that the current intensity in the diagonal ot the bridge is proportional to tile air-tempera ture fluctuations. The recording of the (ut-rent in the diagonal requires arn- plification by a factor of 101, which is acconriplished on a carrier frequency (4 kc) with the use of a phase -sens iti% e detector, so that an output current can be obt~Llned which changes sign with a change in the sign of a temperature fluctuation. The theory of the instrument,Ation is set forth, its design is des- cribed, the results of an experimental investigation of the instrument char- acteristics are presented, and the instrument-calibration and data---,nalysis procedures are described, Bibliography: 26 reference!~.

Tsentr. aerolog. observ. , 1956, Nr 16, pp 39-47 ABSTRACT: A continuation of the experimental investigations by the author on the microstructure of the temperature field in the atmosphere (Dokl. AN SSSR, 1949, Vol 63, Nr 3). The same instrumentation and methodology is used as in the preceding investigations. The measure-, ments were performed during the summer of 1953 at the field station of the Geophysics Institute, Academy of Sciences, USSR. Some data from the earlier investigations are also used. The distribution curves of the temper'ature microfluctuations at fixed reference points exhibit a distinct asymmetry, with the maxima displaced toward the side of the positive fluctuations. This indicates that negative temperature fluctuations are encountered less frequently, but that they have a Card 1/3 greater ampiitude than the positive ones; this can be attributed to SOV/124-57-9-10607 Experimental Determination of the Characteristics of Temperature (cont. ) occasional outbreaks of cold stable air masses. The distribution curves of the synchronous temperature differences between two points located at a base length are of close to normal shape. As the base length is increased ( I = 2 and 32 cm were tested) the frequency distribution curves are substantially "washed out", i. e. , the frequencies of large temperature differences increase. The data of six recordings, with mean values computed up to 20 seconds, are used to investigate the mean-square temperature difference at two points, that is, the root of the structural temperature function H( I T(H') - TFNTYI 2 For 1 ranging from 0.5 to 50 cm the results are closely described by the formula q-H-R-Y 8 2 10 -310.32 where the temperature is given in degree C and b in cm. The exponent 0.32 is extremely close to the theoretical value of 1/3 obtained by A. M. Obukhov (Izv. AN SSSR, ser. geogr. i geofiz. , 1949, Vol 13, Nr 1) and by, M. Yaglom (Dokl. SSSR, 1949, Vol 69). The coefficient of 8.2 x 10-3 6C. cm- A. is several times Card 2/3 SOV/124-57-9- 10607 Experimental Determination of the Characteristics of Temperature (cont. ) smaller than the results of theoretical estimates and the values previously obtained for it by the author. This may perhaps be attributed to the insufficient number of recordings and the insufficient averaging time employed. However, the manual handling of the data for the numerical ' computation of the structural function, when the averaging is done for a period of the order of a few minutes, is extremely time consuming. Therefore, automation of this data handling is desirable, in order that the instrument be capable of determining directly either the structural functions or the correlation moments. L.

TITLE: On Directional Variability of the Wind (K voprosu ob izn-ien- chivosti napravleniVa vetra.) PERIODICAL: Tr. Geofiz. in-ta AN SSSR, 1956, Nr 33 (160), pp 48-59 ABSTRACT: It is shown that if the pulsations of the wind velocity vector are small in comparison with the mean wind velocity U then the longitudinal, structural function of the wind direction is propor- tional to the transverse structural function of the wind speed; and the transverse structural function of the wind direction is proportional to the longitudinal structural function of the wind speed. In both cases the proportionality coefficient is equal to U_ 2. The variability of the wind direction is examined experi- mentally by means of a weathervane equipped with potentiometric gages and an oscillograph. Four of these weathervanes were in- stalled in a straight line in such a way as to enable the author to determine the structural functions for six distances ranging from 50 to 375 meters. Visual analysis of the oscillographic record- Card 1/3 ings made it possible to divide the results obtained into four 124-58-6-6855 Oil Directional Variability of the Wind groups, depending upon the predominant oscillatory frequencies, namely: 1) from 840 to 60 fluctuations in wind direction per hour; 2) from 60 to 12; 3) from 12 to 2; 4) less than 2 hourly fluctuations in wind direction. The inertia of the weathervane had ail adverse effect oil the recordings of the high- frequency fluctuations. The classification of results adopted is similar to that proposed by Singer and Smith (Singer, Irving A., Smith, Maynard E., J. Meteorol. 1953, Vol 10, Nr 2, p 121 - RzhMekh, 1954, Nr 3, abstract 2626). It is shown that with an increase in the mean wind velocity the frequency of the long-period pulsations (group III) diminishes; the frequency of the short period pulsations (group 1) increases, whereas the frequency of pulsations of the intermediate group II does not exhibit any regular variations. The structural function of the wind direction was investigated in two ways; directly by simultaneous registration of readings at several different points, and in- directly - by registrations obtained at different times at the same points (by way of a structural function based on time), founded oil the hypothesis of the translation of the pulsations by the mean flow. For small velocity values the structural function becomes a constant. For velocities of the order of 7 mps, the structural function A( I ) is determined by the relationship A( I ) = B lc~ where the exponent W varies between 0.19 and 0.23 in comformity with the theoretical deductions of A.M. Yaglom (Tr. Geofiz. in-ta AN SSSR, 1954, Card 2/3 124-58-6-6855 On directional Variability of the Wind Nr ?.4) according to which 0< z 0.21. The histograms of the wind direction and wind-direction fluctuation5 for different time intervals and different mean velocities are also analyzed. L. S. Gandin 1.

The upper portion is considered loaded by the active pressure of the fill. The lower portion is calculated as a bar which is elastically - fastened to an elastic semi-plane. The contact problem is solved for an elastic bar and semi-plane with a load and moment representing the action which the fill exerts on the bar. No account is taken of the discontinuity in the semi-plane created by the insertion of the bar. The friction between the soil and the plank is disr"egarded. The Card 1/3 stresses in the serni-plane are determined by means of Melan'5 V, 124-11-13209 Calculation Method for Plank Walls as Elastic Structural Elements with Due Consider- ation to the Compressibility of the Ground in the Restraining Encasement Area.
