Small-scale high wind cores enhancing low-level wind shear: Doppler radar observation of opposing wind adjacent to the sea-breeze frontal zone on 20 September 1989

Summary Opposing wind region adjacent to the sea-breeze frontal zone on 20 September 1989 was investigated observationally using the data from a single Doppler radar measurement.Found are small-scale high wind cores located close to the zone. Their location is at the altitude of several hundred meters and their sizes are around several hundred meters. It is demonstrated that these cores have an effect of enhancing low-level wind shear associated with the sea-breeze frontal zone.With 9 Figures
