Abstract
The paper describes the special features of the F-type radiosonde in distinguishing from the rotation of the fan whether the downward movement of the radiosonde balloon is due to a strong vertical downward current or due to the accumulation of snow. It shows how the rate of rotation of the fan can be used to identify regions of turbulence in the atmosphere. The observations of the turbulence with the F-type radiosonde are compared with the inferences drawn by turbasondes in the U.S.A. and the Dines meteorograph records in India, The regions where turbulence may be observed in India have been indicated. The existence of severe turbulence in the upper troposphere and in the stratosphere has been emphasised.
