## Abstract Simultaneous records of temperature fluctuations and wind speed at several heights have been obtained with instruments suspended from captive balloons flying 225 m above level, uniform land. Variations in the horizontal wind speed near the ground appear to be associated with bursts of

The coherence for streamwise and cross-stream wind components is studied at four meteorological sites and compared with a representative wind-tunnel experiment. The coherence is approximated by a negative exponential in terms of a non-dimensional frequency, Af, and a decay parameter, a. Theoretical
## Abstract Records of vertical gustiness have been obtained using a sensitive vane attached to the cable of a captive balloon. Electrical filtering of the output signal from the vane reduced the labour of subsequent computation. Intensities of turbulence were found to decrease with increasing wind
