Beat-tYPe oscillations in the electromagnetic fiel Id TITLE. of the earth (according to observations in Irkutsk) ,PERIODICAL: Geologiya i geofizika, no.11, 1962, 114-124 TEXT; Regular observations of.PP-oacillations were begun at Irkutsk in August 1957. The present paper reports results obtained. as a result of four years of-observatioha. The PP-oscillations have the form of beats. The most frequently encountered rqpetition frequency of these beats was found to be 0.3 to 0.1 cps. The most frequently encountered frequency-of the "carrier" was found to correspond to a period of 0.6 to '1.0 sec. Finally, the maximum amplitude of the res 'ultant oscillation was found to lie between 0.05 and 2.5 mV/km, but the most frequently encountered values were in the range 0.15 to 0.60 mV/km. A study was also made of the diurnal variations in the frequency of appearance of the PP-oacillations, the diurnal variation in their intensity and.,. the seasonal distribution, A further study,was concerned with changes'in the ionosphere during PP-oscillations and their geographical distribution.
