Prof. Chapman was the official delegate of the American Meteorological Society to the XVIIth International Geological Congress held in Russia last summer; this report of his visit to some of the USSR polar meteorological stations should be of much interest to American meteorologists, because our continent has the same kind of meteorological-geographical relations to the Arctic Ocean: a large extent of low tundra land in the north reaching to the 80th parallel over which polar continental air builds up and finds a chute to slip its chilly freight directly into lower latitudes; we too have a chain of high-latitude meteorological stations to warn us of polar outbreaks. However, information from north of Siberia (Wrangell Is. region) seems to be almost as important to us as that from Alaska and northern Canada and Greenland; daily reports are now being received here from the more easterly section of the Siberian Arctic coast, thanks to the stations opened there by the Soviets and to their cooperation in transmitting them more quickly and directly than possible heretofore. The meteorological and aerological observations from the Russian polar stations are summarized and published in the “10-day bulletins of the General Admin, of the No. Sea Routes” (Moscow) and in the “Bulletins” and “Transactions of the Arctic Institute” (Leningrad). A discussion of the radiometeoro graph soundings made at some of these stations appeared in the October Bulletin Amer. Met. Soc., pp. 322 ff.—Editor.
