| 摘 要： | 应用SVD技术，诊断分析了北半球500hPa高度场与山东春季降水的关系。结果表明：山东春季降水与北半球500hPa高度场关系密切，山东春季降水与东亚上空500hPa高度场具有很好的同步联系。前期(冬季)日本东北部500hPa高度场是影响山东南部春季降水的关键区，具有预测意义。500hPa高度距平场东高西低型是造成山东春季降水的主要大气环流形势，西高东低型是造成山东少雨的主要大气环流形势。 |
| 关 键 词： | SVD技术 山东春季降水 大气环流 |

| Abstract: | Using the singular value decomposition(SVD) method, we study the relationship between 500hPa height and spring precipitation in Shandong Province. The results show that the spring precipitation in Shandong Province has a good relationship with the 500hPa height in the north hemisphere. And the spring precipitation in Shandong Province also has a good synchronous relationship with the 500hPa height in East Asia. The 500hPa height of prior period (winter) in northeast of Japan is the "key region" to forecast the spring precipitation in the south of Shandong Province. The atmospheric circulation pattern of higher in the east and lower in the west causes much spring precipitation in Shandong province, and on the other hand the pattern of higher in the west and lower in the east causes little spring precipitation. |
