    摘要:

    利用河北省及周边73个台站1961—2010年春季、秋季降水资料及NCEP/NCAR再分析资料,应用SVD等多种统计方法探讨了河北春秋季降水异常变化及其与对流层中低层环流的可能联系.研究结果表明:河北省春秋季降水异常存在全省一致和南—北相反两种模态.春季,当500 hPa平均高度场上东西伯利亚海出现负异常,我国东北地区到日本海为正异常时,河北春季大部分地区降水偏多(石家庄表现最明显);反之,河北春季大部分地区降水偏少.秋季,当欧洲的西北部500 hPa平均高度场为负异常时,河北大部秋季降水偏少(中部表现最明显);反之,河北秋季降水偏多.春秋季干旱的出现与贝加尔湖阻高(或高脊)及东亚大槽偏强有关.850 hPa偏南风减弱是导致春秋季干旱的重要原因.

    Abstract:

    Based on monthly spring and autumn precipitation data during 1961-2010 from 73 meteorological stations in Hebei province and its vicinity, as well as the NCEP/NCAR reanalysis data during the same period, the variations of spring and autumn precipitation anomaly in Hebei province and its possible relationship with the middle and low level circulation are analyzed by using Singular Value Decomposition (SVD) analysis method. Results indicate that the uniformly dry/wet is the most common pattern for the spatial distribution of spring and autumn rainfall in Hebei, and the second pattern is a seesaw of dry/wet between southern and northern regions. When the negative anomaly over east Siberian Sea and positive anomaly from Northeast China to Japan Sea emerge at 500 hPa geopotential height fields in spring, the contemporaneous spring precipitation in most parts of Hebei, especially Shijiazhuang, is above normal;otherwise, precipitation in spring is below normal. When the negative anomaly over Northwest Europe emerges at 500 hPa geopotential height fields in autumn, the contemporaneous precipitation in most parts of Hebei, especially middle areas, is below normal;otherwise, the precipitation in autumn is above normal. The spring and autumn droughts in Hebei are related to the stronger Baikal blocking high (or high pressure ridge) and the East Asian trough, and the weakened 850 hPa seasonal south winds cause contemporaneous droughts in Hebei.
