We simulated a meandering effect of wind direction fluctuation on horizontal gas diffusion over Mt. Tsukuba, using a rotating turntable in the wind tunnel experiment. Experimental results were validated with field data observed by Japan Atomic Energy Research Institute (JAERI), 1989 and 1990. We also simulated actual unsteady phenomena of airflow and gas diffusion over Mt. Tsukuba, and compared the calculated results with field data. Both data agreed well under neutral, stable and unstable atmospheric stabilities.
