| 摘 要： | 利用1979～2008年NCEP/NCAR再分析资料与中国160站降水资料,探讨夏季逐月东亚高空急流异常与淮河流域降水的关系.研究表明,夏季淮河流域降水多寡与东亚高空急流月际变化密切相关.6月淮河流域降水偏多(偏少)的环流特征为东亚高空西风急流位置比气候态偏北(偏南),亚洲中高纬地区呈两脊一槽(两槽一脊)环流型,影响我...

| Abstract: | Relationship between the East Asia Westerly Jet(EAWJ) and the Huaihe River Valley(HRV) summer rainfall was investigated month by month,using the NCEP/NCAR reanalysis data and the monthly rainfall data at 160 stations in China from 1979 to 2008.It was found that the HRV summer rainfall is closely related to the monthly variation of the EAWJ.In the years with more rainfall over the HRV,the EAWJ is located northward than normal and the circulation pattern exhibits two ridges and one trough in mid-high latitude... |
