| 摘 要： | 采用一种能够反映热带海气相互作用区域特性的指数，分析了热带５个洋区（西太平洋、中太平洋、东太平洋、大西洋、印度洋）的海气相互作用指数与山东夏季（６～８月）降水的相互联系。结果表明，只有热带印度洋的海气相互作用的第１模态与山东夏季降水存在的显著相关。热带印度洋海温偏高时山东夏季降水偏少，反之偏多。热带西印度洋区域１０００ｈＰａ风向赤道区域异常辐合，并伴随出现正海表温度异常的年份，山东夏季降水往往偏少

| Abstract: | WT5BZ]An index which can show the regional features of atmosphere ocean interaction in tropical zones is used in the paper. Correlation between summer rainfall(Jun. to Aug.) in Shandong province and atmosphere ocean interaction in five tropical regions which are the western ,central and eastern Pacific,the Indian Ocean and the Atlantic is analyzed based on the index. The results illustrate that significant correlation exists only between atmosphere ocean interaction in tropic Indian Ocean and summer precipitation in Shandong province. There is probably less(more) summer rainfall in Shandong when Indian Ocean has rather higher(lower) sea surface temperature(SST).In addition, when wind at 1000hPa over western tropic Indian Ocean converges equatorward exceptionally and positive SST anormaly appears simultaneously, dry summer often occurs in the province. Further studies also demonstrate that the changes of summer rainfall in different districts in Shandong province are likely to connect with the weakening of westerly at 1000hPa over tropical Indian Ocean and westward SST gradient.
