摘要
提出一种基于观测数据获取率、获取准时率、质量控制正确率和模式一致率的综合名单控制方法,使用2019年全国120个探空站测风数据对该方法进行验证,并对观测数据质量进行分析。结果显示:名单控制可以有效检查出观测数据存在问题的站点,名单站点观测数据相对于模式数据存在明显的系统性偏差,偏差和均方根误差相对于全国平均值都显著偏大。探空测风数据质量较好,四季风向、风速观测数据和模式数据较为一致,偏差分别在±1°和±1.5 m·s^(-1)内;秋季风向一致性较好;夏季和冬季风速一致性低于春季和秋季;风向一致性春季和夏季随气压减小先减小后增大,秋季和冬季则相反;风速一致性随气压减小基本呈三峰型变化。
A list control method is proposed,which considers the acquisition rate,acquisition punctuality rate,quality control accuracy rate and model consistency rate of observation data.The wind observation data of 120 radiosonde stations in 2019 are used to validate the method,and analyze the quality of observation data.The results are as follows.The stations with observation data problems can be effectively checked out by the list control method.Compared with the model data,the observation data of the list stations have obvious systematic deviation,and the bias and root mean square error(RMSE) are significantly larger than the national averages.The quality of radiosonde wind observation data is good,and the wind direction and wind speed observation data are relatively consistent with the model data in all the four seasons with the biases are within ±1° and ±1.5 m·s^(-1),respectively.The wind direction consistency in autumn is the highest,and the wind speed consistency in summer and winter is lower than that in spring and autumn.The wind direction consistency first decreases and then increases with the decrease of pressure in spring and summer,while it is opposite in autumn and winter.The wind speed consistency basically changes in a three-peak pattern with the decrease of pressure.
