The meteorograph records of the almost daily ascents over England during the months of April, 1939, and September, 1930, have been evaluated according to a method described in an earlier paper. ( Q.J. 70 , 1944, p. 293). The humidities so obtained indicate (1) that supersaturation with respect to ice is very frequently found in the upper troposphere; (2) that, within the stratosphere, dry air of a humidity mixing ratio of about 10 −5 sometimes does occur, which can only be explained as tropical stratosphere air; (3) that, on one occasion, very dry air from the stratosphere appears to have been drawn into the uppermost regions of the troposphere.
