摘要
为更准确的研究气象因素对成都市空气质量的影响,需要进一步提高天气预报模式WRF的模拟效果。设定16种天气预报模式WRF中尺度数值模式的参数化方案与气象信息综合分析处理系统(MICAPs)的气象实测数据进行地表温度(T2m)和海平面气压(Psl)及高空温度的比对,通过统计学方法进行结果评估,选取适用于成都市本地化的天气预报模式WRF参数方案。结果表明:第15组参数化方案模拟结果与气象信息综合分析处理系统(MICAPs)气象实测数据的对比分析效果表现最佳,是为成都市空气质量预报中天气预报模式WRF的最优参数设置,第11组次之。
Simulation performance of WRF should be improved for a more accurate study on the effects of meteorologi- cal elements to Chengdu air quality. Sixteen schemes were designed in this study. Model outputs and MICAPs data including 2m-temperature（Tzm）, pressure of sea level（Pu ） and high-altitude temperature were selected for statistical analysis. Localized selection of the WRF model parameter schemes in Chengdu was realized by statistical evaluation of the model outputs. The results showed that the 15th group of parameter schemes gave the best simulation performance followed by the 11th one.
