摘要: 利用1979—2008年GPCP世界逐月降水数据以及NCEP/NCAR的研究数据,并应用相关分析与合成分析等多种方式,对西北干旱地区最近30 a以来春季的降水特点以及与高度场、水平风场相关分布特征展开研究。结果表明:西北干旱区近30 a来春季的降水量变化呈增加趋势;200 h Pa纬向风场、东亚大槽以及南亚高压对西北干旱区春季降水有重要影响。

Abstract: Using 1979—2008 GPCP global monthly precipitation data and NCEP/NCAR reanalysis data,and using synthesis and correlation analysis and other statistical methods to analyze the northwest arid area for nearly 30 years with spring rainfall characteristics,height fields and horizontal wind field associated distribution. The results showed that northwest arid area in nearly 30 years of spring precipitation increasing trend;200 hpa zonal wind,and South East Asian trough northwest arid area of high pressure on spring precipitation have a major impact.
