この論文をさがす

説明

Observations of the turbulence in the atmospheric boundary layer have been made in the summer season 2013 using sonic anemometer-thermometers on a meteorological tower (55-m tall) of the Observation and Analysis System for Local Unusual Weather and a Doppler lidar in the Ujigawa Open Laboratory. Here, typical examinations under unstable conditions are presented. An ascending large-scale area with the time scale of more than 100 s was observed. This structure appears to correspond to the plume structure forced by buoyancy in the heated lower layer. After the passage of the ascending area, the area of strong winds was observed in the surface layer. From the analysis of wavelet transform for the vertical velocity, intermittent occurrence of large-scale structures is revealed.
