Research Abstract

With a view to improve quantitative precipitation forecast by the estimation of the various cloud microphysics based on the data assimilation of the polarimetric radar, the assimilation method of the precipitation type estimated by the polarimetric radar was developed, in addition, the effect on the QPF by the assimilation of the vertical profile of vapor was evaluated, which brought to realization on the advanced techniques of QPF.
