The Initial Capability of X-Band Polarimetric Radar to Gap-Fill A S-Band and C-Band Radar Network for Convective Rainbands in Eastern China

The unique network consisting of three different wavelength (C-, S- and X-band) radar in Eastern China is utilized to demonstrate their coordination capability of better coverage of low atmospheric layers in convective situations. After correcting attenuation effects on horizontal reflectivity (ZH) of all three wavelength radars based on the self-consistency approach, X-band radar exhibits even larger ZH than S- and C-band, which exactly captures the severe developing convective rainbands on the lower atmospheric layer. In this sense, the X-band radar effectively plays a gap-filling coordination role in this S- and C-band radar network in convective situations.
