Abstract
Based on continuous observations of the planetary boundary layer (PBL) with an L-band (1357.5 MHz) boundary-layer radar (BLR) at a hilly loc ation in Japan, we have discovered that on clear days, a thin enhanced echo layer corresponding to the top of the PBL (or mixed layer) appea red at about 500 m height in the morning and ascended to about 1500 m in the afternoon. Strong upward velocities were observed below the ech o layer (or inside the PBL), reaching 1500 m in the afternoon.
