| 摘 要： | 使用1951—2000年相关资料,分析了夏季偏南风强度和夏季风北边缘、冬季风指数和春季偏北风以及沙尘暴的年际、年代际变化,并研究了它们的联系过程。结果表明,夏季风北边缘与沙尘暴、北边缘与冬季风和冬季风与沙尘暴的距平相关百分率分别是0.75,0.58和0.70,而且7~8月110°~120°E偏南风和12月~2月90°~100°E偏北风与3~5月90°~100°E偏北风的分析结果也相同。它们相互联系的过程是:夏季偏南风偏强(弱)—北边缘偏北(南)—冬季风偏强(弱)—冷空气偏强(弱)—春季偏北风偏强(弱)—沙尘暴偏多(少)。这些为沙尘暴的长期预测提供了一个新的事实依据。 |

| Abstract: | Using NCEP/NCAR and sand-dust storm data,the summer south wind,northern edge,winder monsoon index,spring north wind and sand-dust storm were analyzed on their interannual and interdecadal change.And their contact process each other were investigated.The results are as follows: The summer monsoon is stronger(weaker)-the northern edge is far north(south)-the winter monsoon is stronger(weaker)-the winter cold air is stronger(weaker)-the spring north wind is stronger(weaker)-the sand-dust storm is more(less),and provides the new idea for long-term forecast. |
| Keywords: | The northern edge of summer monsoon Winter monsoon index Sand-dust storm |
