| 摘 要： | 通过白银市春末夏初干旱指数1] 与北半球 50 0hPa、10 0hPa海平面气压和太平洋海温的月平均环流典型年的对比分析、相关分析发现 ,春末夏初干旱与这些环流背景有密切关系 ,在此基础上 ,提取了选入预测模型的因子。用 3种方法建立预测模型 ,再进行预测集成 ,试报了 1991～ 1998年的春末夏初干旱指数 ,效果很好

| Abstract: | The drought indexes from later spring to early summer in Baiging,the pressure at 500hPa,100hPa and SST in nothern himsphere and temperature monthly average over Pacific are analyed to pick up the factors for predictive model.There mothods are used for setting up model and then collecting them for predicting drought. |
