Abstract
WE learn from an article by Prof. P. A. Molchanov in the Moscow News that the recent All-Union Conference for the Study of the Stratosphere decided to call an international conference, with the same objects, to meet in the U.S.S.R. in 1936, the date to be fixed in relation to the total solar eclipse. The Soviet conference of last spring was mainly devoted to a review of the present state of knowledge of the problems of the extra-tropospherio regions of the atmosphere, with some references to their relation to the meteorological processes of the troposphere. Molchanov dealt with exploration by ballon sonde and radio sonde, and with the role of the stratosphere as stabiliser in atmospheric processes. Andriev discussed acoustic methods of investigation, and attention was specially directed to the prominence of the warm sound-reflecting regions during the polar night, at heights believed to be of the order of 30 km., and therefore likely to be accessible to the ballon sonde. Andriev also laid stress on the existence of air masses of unequal densities in the stratosphere, and urged their closer study. Ionospheric problems were treated by Tverskoi, who discussed the sources of ionisation in the atmosphere, and Bontch-Bruewitch, who reviewed the results of experimental soundings of the ionosphere (NATURE, Feb. 3, 1934, p. 175). Special enthusiasm was shown in the section of the conference dealing with cosmic rays, Joffe, Skobeltzyn and Eigenson being among the speakers. Detailed discussion of the stratostat and the stratospheric aeroplane occupied the technical section. The conference, under the presidency of Vavilov, passed resolutions dealing with the world conference, as already mentioned, and with the special need of co-operation among Soviet, American and Canadian scientific workers in polar atmospheric researches.
