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 threemonth examination period, it is shown that the method improves the checking capability greatly.
