在cop IOP 9c期间，研究了将传统和全球定位系统（GPS）在法国的天顶总延迟（ZTD）数据吸收到天气研究和预报（WRF）模型中的影响。选择了一个对流允许的水平分辨率为3.6公里，覆盖整个中欧。通过4种不同的模拟来说明同化不同观测类型对预报的影响。此外，还与德国气象局（DWD）的COSMO‐DE和COSMO‐EU模式进行了比较。结果表明，将数据同化到欧洲上空的WRF模式允许对流的配置中有明显的积极影响。GPS - ZTD资料的额外同化进一步改善了综合水汽（IWV）相关性，但对降水预测的影响并不明显。与探空资料的比较表明，12 h后的湿度结构有正向影响，但降水仍然存在高估。与cop IOP期间运行的高分辨率DWD模式的进一步比较表明，DWD对初始边界层风场的依赖性很强，特别是近地面风场在ECMWF分析中比在COSMO分析中表现得更好。据我们所知，这是第一次在欧洲上空应用允许对流的WRF配置的研究，它可以作为进一步研究的指导。版权所有©2011英国皇家气象学会
The impact of assimilating conventional and Global Positioning System (GPS) Zenith Total Delay (ZTD) data over France into the Weather Research and Forecasting (WRF) model is investigated during COPS IOP 9c. A convection‐permitting horizontal resolution of 3.6 km covering the whole of central Europe was chosen. Four different simulations were conducted to show the influence of assimilating different observation types on the forecast. Additionally, a comparison with the models COSMO‐DE and COSMO‐EU from the German Meteorological Service (DWD) was performed.The results show a clear positive impact of assimilating data into a convection‐permitting configuration of the WRF model over Europe. The additional assimilation of GPS‐ZTD data shows a further improvement of integrated water vapour (IWV) correlation, but the influence on prediction of precipitation was not necessarily clear. A comparison with radiosonde data shows a positive impact on the humidity structure after 12 hours, while an overestimation of precipitation still remains.A further comparison with the operational high‐resolution models of DWD during this COPS IOP reveals a strong dependence on the initial boundary‐layer wind field especially as the near‐surface wind field is better represented in the ECMWF analysis than in the COSMO analysis.As this is, to our knowledge, the first study applying a convection‐permitting configuration of WRF over Europe, it can be used as a guidance for further studies.
