| Abstract |
The results from 34 'constant level' tetroon flights made near St. Cloud, Minnesota, and tracked with the METRAC positioning system are presented. These flights were made throughout the year and primarily at heights between 700 and 1400 meters above the surface. Flight times ranged in length from 2100 to 6000 seconds. Three-dimensional velocity variances, autocorrelation functions, power spectra and diffusion coefficients are presented. Relationships showing an increase of vertical velocity variance with decreasing atmospheric stability and with increased wind speed are illustrated. |
