Abstract Conventional soundings are rather limited over the western North Pacific and can be largely compensated by GNSS radio occultation (RO) data. We utilize GSI hybrid assimilation system to assimilate RO data multi-resolution global model (MPAS) investigate impact on prediction of Typhoon Nepartak that passed southern Taiwan in 2016. In this study, performances with local refractivity bend...
