Abstract
Pulsations of the lapse rate between 1 and 5 m were recorded on a sunny day over a field of tall weeds (z 0 ≈ 6 cm) and over a parking lot (z 0 ≈ 0.1 cm). The frequency distributions of values recorded every 2 sec in a 20 min span were nearly identical in the two environments. Values ranged from inversions of 0.75 °C to lapses of 1.75 °C. There was a tendency for a wider range of fluctuations in short time intervals in the weeds than over the smoother parking lot. The data suggest that these very short-periodic fluctuations were dynamically induced.
