摘要：
The cloud analysis procedure of the Advanced Regional Prediction System (ARPS) is implemented in a proposed operational numerical forecast system composed of the Grid-point Statistical Interpolation (GSI) and the Advanced Research WRF (WRF-ARW). The case of 23 May 2005 Central Plains storm cluster is used to assess the impact of the cloud analysis using reflectivity data from six operational WSR-88D radars within the proposed operational configuration on 6-h forecast of the storm cluster. The cloud analysis is shown to significantly reduce the spin-up problem and improve the short-range forecast for the storm cluster, even at the relatively coarse 9 km resolution.
