MEASUREMENT OF TURBULENT KINETIC ENERGY BUDGET IN THE ATMOSPHERIC BOUNDARY LAYER

The turbulent kinetic energy budget was examined experimentally including the directmeasurement of the pressure transport term by the use of the newly designed static pressureprobe. Observations were made at three levels, 25 m, 50 m, and l00m on the tower, and theenergy budgets were examined at two layers, 25-50 m (lower layer) and 50-100 m (upperlayer). In the unstable case, the pressure transport term was found to be energy loss and toinclude large errors. However, the kinetic energy balance was satisfied much better byconsidering the pressure transpot term in stable condition.The turbulent kinetic energy budget was examined experimentally including the directmeasurement of the pressure transport term by the use of the newly designed static pressureprobe.
