It is well known that the high-resolution numerical model analyses and forecasts benefit from the assimilation of satellite data like radiances and satellite-derived wind. The satellite-derived wind (or AMVs) from the cloud and moisture features of geostationary satellites are very important and valuable with high temporal frequency data to create more accurate analysis fields. The study based on satellite data assimilation and the impact study using the NOAA’s high resolution (~3-km) ensemble based NSSL experimental WoF (NEWS-e) system. In this study, the satellite data sets assimilated are (1) the clear-sky hyperspectral radiances from AIRS and the CrIS and (2) the atmospheric motion vectors (AMVs) from GOES-16 geostationary satellite. Multiple convective events are considered during the year 2016 and 2017 and 2018 to assess the potential of assimilating satellite data into the WoF system to improving forecasts of high impact weather events. The results show positive impacts on severe storm predictions.
