Turbulence Measurements on a Forty-Eight Meter Tower in Desert Terrain.
Abstract
This is a data report for which turbulence, wind and temperature profiles were collected on a 48 m tower for 10 minute periods every data collection hour. Net radiation measurements were made and averaged for half hour periods every hour. Salt Lake City rawinsondes were collected at 0500 and 1700 hours local time. Dugway West Vertical Grid morning rawinsondes and afternoon 10 gram pilot balloon soundings were collected daily. The tower and net radiometer data were collected at Dugway West Vertical Grid every successful data collection hour of the day between 0900 Monday and 1500 Friday for an 8 week period, February 14 through April 8, 1977. All tower data were smoothed. Both observed and smoothed data are reproduced. Calculation of stability parameters; Richardson's number, Monin-Obukhov length scale and bulk Richardson's number are prepared for four layers. Friction velocity is calculated for the lowest three layers. Power law exponents are calculated for wind speed and turbulence. Approximately 50 percent of the data are associated with 8 m wind speeds of 3 m/s or more and are suitable for classical profile analysis. Known universal methods of data analysis are presented. Pasquill stability categories for these data are tabulated. (Author)
