Description:In an experiment involving six passes through cumulus clouds on October 27, 1969, the draft scale vertical motions determined from the RFF inertial platform gust probe were com' pared with those computed from the conventional DC-6 output of pitch angle,' true air speed, and radio altimeter. The results showed a high correlation between the two records of vertical motion particularly where no power setting changes were made during straight line flights through six cumulus c ouds over the Florida Everglades. Indications are that the conventional method of measuring vertical motions provides useful accuracy in the study of individual cumulus clouds. An analysis of vertical draft velocity in Hurricane Debbie (1969) yielded reasonable profiles of vertical motions across the eye and wall cloud of the hurricane.
