Abstract:

This report describes a sensitive, three-bladed anemometer used to measure vertical air motion. The anemometer has a starting speed of less than 10 cmsec., responds linearly to the vertical component of the wind and has an average distance constant of 1.0 meter. Observations of vertical velocity made at several different sites at Centerton are included. Various analyses of the data have been performed including 76 spectral analyses of simultaneous records of vertical and horizontal velocities, frequency histograms of sustained bursts of vertical activity, and studies of the time and space averaged values of u and w. Conclusions concerning the relative influence of vertical winds and of terrain on wind are included. Author
