| 摘 要： | 分析了近50年青藏高原地面加热场强度距平指数、Ni~no C区海温指数、SOI和印缅槽指数的统计相关,结果表明,ENSO指数和印缅槽指数在月、季时间尺度上具有很好的持续性。青藏高原地面加热场强度距平指数和印缅槽指数与Ni~no C区海温指数存在很好的正相关,与SOI有显著的负相关。由此建立了一个通过印缅槽将ENSO循环与青藏高原地面加热场联系起来,解释西北区东部及河套干旱形成的概念模型。 |
| 关 键 词： | 青藏高原 地面加热场强度 ENSO 印缅槽 |

| Abstract: | Using the data of intensity departure index of surface heating fields over Qinghai-Xizang Plateau,the indexes of the SST of the Nio C,SOI and the intensity of the India-Burma trough in recent 50 years,The result shows that there is a good persistence for index of ENSO and the intensity of the India-Burma trough in month and season time scales.It has a good positive relation that the intensity departure index of surface heating fields over Qinghai-Xizang Plateau and index of the intensity of the India-Burma troughwith index of the SST of the Nio C,but it has a good negative with SOI.A concept modelhas been get up by above research,this model was contacted that ENSO circulation and surface heating fields over Qinghai-Xizang Plateau by India-Burma trough that explain the dry of the northwest eastern region and the Hetao and its vicinity area. |
| Keywords: | Qinghai-Xizang Plateau Intensity of the surface heating field ENSO India-Burma trough |
