The turbulent structure of the internal boundary layer near the shore

摘要: A field experiment to measure the turbulent structure of internal boundary layer near shore was conducted using three instrumented meteorological poles, a kytoon, and crane-mounted ultrasonic anemometer-thermometer, as well reference anemometer-thermometers positioned poles. Part 1 this study gives explicit details general characteristics for one run experiment. 2 (Ohara Ogawa, 1984) will present similarity energy budget analysis. The mean velocity profiles showed that there wind speed acceleration due sea-land temperature difference. In addition, consisted distinct regions; region ground had largest gradient followed by transition zone which small gradient, while above, profile resembled oncoming sea breeze. general, turbulence greatest shore, gradually decreasing inland. lowest large intensities some intermittent between lower strong unstable relatively turbulent-free above.
