Implementation and evaluation of cloud analysis with WSR-88D reflectivity data for GSI and WRF-ARW

چکیده
[1] 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.

The thunderstorms are typical mesoscale systems dominated by intense convection. Mesoscale models are essential for the accurate prediction of such high-impact weather events. In the present study, an attempt has been made to compare the simulated results of three thunderstorm events using NMM and ARW model core of WRF system and validated the model results with observations. Both models perfor...
