Assimilation of the radar-derived water vapour mixing ratio into the LM COSMO model with a high horizontal resolution
Original language description
We describe the application of the WVC (Water Vapour Correction) method to assimilate radar reflectivity into the NWP (Numerical Weather Prediction) Local Model COSMO (LM; version 3.18) with a horizontal resolution of 2.8 km. The method is applied to five severe convective events and compared with the latent heat nudging method (LHN). Results show that in most studied cases, both methods can forecast precipitation development three hours ahead, which is approximately the life cycle length of studied storms, and that the assimilation significantly improves precipitation forecasts obtained by the NWP model. The results show that WVC yields better results than LHN in some cases and could be a good alternative to LHN.
