中文摘要: 将一定范围内的邻近气象站按四方位进行分组,然后将被检站的气象资料与各组分别进行比较分析,并根据大气规律进行判断。在冷空气或雷暴等天气系统影响下,当气象资料的水平分布出现明显的不连续现象时,使用该方法可以降低误检率。利用该方法,对浙江省76个自动气象站的气温和降水资料进行实时质量控制,经过3个月的试验,效果明显。

Abstract:The method of horizontal space consistency analysis is put forward.The characteristics of the method consist of the following three steps: (1)The weather stations near the checked station are divided into four groups according to the four directions;(2)The data of the checked station are compared with the data of its surrounding stations;(3) The comparison results are used to judge the data are true or false according to the atmospheric principles. When the cold air and the thunderstorm appear, the physical quantity is distinctly discontinued.Thus, this method can be used to reduce the checking errors, and it is used in the Zhejiang to check the temperature and precipitation data at the 76 automatic weather stations. After a three month examination period, it is shown that the method improves the checking capability greatly.
