利用美国东部地区气象研究与预报（WRF）/社区多尺度空气质量（CMAQ）系统7年4 km空间分辨率的模拟结果，分析了该系统在美国东部地区的性能。对于2 m温度，月平均偏差（MB）和粗差（GE）值基本上在推荐的性能标准之内。尽管温度被过高预测，MB值高达2K。2米处的水蒸气预测良好，但在冬季观察到显著偏差（>2 g kg（-1））。风速的预测是令人满意的，但在0 < MB时偏向于过度预测
The performance of the Weather Research and Forecasting (WRF)/Community Multi-scale Air Quality (CMAQ) system in the eastern United States is analyzed based on results from a seven-year modeling study with a 4-km spatial resolution.For 2-m temperature, the monthly averaged mean bias (MB) and gross error (GE) values are generally within the recommended performance criteria, although temperature is over-predicted with MB values up to 2 K. Water vapor at 2-m is well-predicted but significant biases (>2 g kg(-1)) were observed in wintertime. Predictions for wind speed are satisfactory but biased towards over-prediction with 0 < MB
