Abstract:
Weather Radar Center (WRC) in Korea Meteorological Administration (KMA) installed the Yong-In Testbed radar to examine the dual-pol. radar (S-band) variables and to develop the algorithms for applying to the operational dual-pol. radar network on August 2014. And it established the verification site at Jincheon located 28 km distance from YIT radar for the investigation of dual-pol. radar data and products on March 2014. There are the instruments of 2DVD (2-Dimensional Video Disdrometer), PARSIVEL (the laser-optical Particle Size Velocity), the tipping-bucket raingauges and the weighting raingauges at the verification site. This study analyses the heavy rainfall case such as typhoon, Chang-ma front from 2014 to 2015. WRC investigates the bias of the reflectivities (Z), differential reflectivities (ZDR) and computes the hydrometeor classification and the radar rainfall estimation. And WRC also calculate Korean equations R(Z, ZDR) for the radar rainfall estimation using 2DVD data and verifies the accuracy of the rainfall estimation for the heavy rainfall cases. We will investigate the characteristics of Korean rainfall system by using YIT radar continuously.
