摘要

摘要: 采用1951~1990年我国690个站年平均风速资料, 进行均一性检验.结果表明SNHT方法适用于风速的均一性检验.我国年平均风速质量基本可靠.仪器变化是引起非均一的主要原因.
- 年平均风速;
- 均一性;
- SNHT方法;
- 检验
Abstract: The homogeneity test is carried out using mean annual wind speed series over China from 1951 to 1990. The results indicate that Standard Normal Homogeneity Test (SNHT) method could be applied to the homogeneity test on wind speed. The data quality of mean annual wind speed series is basically reliable. The significant inhomogeneity is related to instrument change.
