摘要
Abstract
Monthly maximum, minimum and mean temperature data of Urumqi meteorological station from 1951 to 2008 were tested by using standard normal test （SNHT） method, and the breakpoint because of relocation was corrected using the D-value method. The results revealed that abrupt points in monthly sequences mainly corresponded to those in annual sequences, and those points of the temperature occurred in 1975, when the meteorological station relocated far from the original station. Monthly test results showed that temperature sequences from May to September were more influenced by relocation of the station, and there were some abrupt points at significant level of 0.05. Using the accumulative anomaly method to analyze the change trend of temperature sequences from May to September based on the different weights, it was found that there is a notable change after correction.关键词
