Abstract:

The 1428-ft television transmitter tower, located at Cedar Hill, Texas, and instrumented to obtain continuous measurements of wind and temperature at 12 levels from 30 ft to 1420 ft above ground, is proving to be a useful research tool for investigating low-level meteorological phe nomena, especially the low-level jet. During the night of 22-23 February 1961, a pronounced lowlevel jet was recorded. Systematic variations of wind speed and temperature with time and height will be discussed to illustrate the orderly development of the low-level jet, the upward growth of the nocturnal inversion, and the vertical extent of the mixing process within the deepening inversion.
