Polarimetric radar data (PRD) have potential to be used in numerical weather prediction (NWP) models improve convective-scale forecasts. However, thus far only a few studies been undertaken this research direction. To assimilate PRD NWP models, forward operator, also called simulator, is needed establish the relation between model physics parameters and polarimetric variables. Such operator nee...

The development of high-resolution nonhydrostatic models and the rapid increase of computer power are making the explicit prediction of thunderstorms a reality (Droegemeier 1990; Lilly 1990; Droegemeier 1997; Xue et al. 2003, X03 hereafter). Data assimilation plays an important role in providing an accurate initial condition for the model forecast. The operational US WSR88D Doppler radar networ...
