摘要/Abstract

摘要： 基于CRU_TS4.0数据、东亚夏季风指数和南亚夏季风指数，使用偏相关分析方法，分析青藏高原1970-2014年间夏季（6-8月）降水的变化趋势及其对东亚夏季风（EASM）和南亚夏季风（SASM）响应的格局。结果表明：SASM与青藏高原夏季降水显著性相关的范围要明显大于EASM，SASM正相关区域位于青藏高原南部地区，负相关区域位于正相关区域外围、高大山体后部的高原西缘、中部和北部地区。EASM与高原夏季降水正相关区域集中分布于柴达木盆地，负相关区域面积较大，主要位于高原的中部和西部地区。

关键词: 东亚夏季风, 南亚夏季风, CRU_TS4.0数据, 偏相关分析, 青藏高原夏季降水

Abstract: Influence of East Asian summer monsoon (EASM) and South Asian summer monsoon (SASM) on summer precipitation in Qinghai-Tibetan Plateau was evaluated, based on dataset CRU_TS4.0, East Asian summer monsoon index (EASMI), and South Asian summer monsoon index (SASMI). By using partial correlation method, the tempo-spatial pattern of summer precipitation in the region was also examined. The results showed that SASM was associated with much larger area than EASM.SASM was positively correlated with precipitation in part of the southern plateau,while was negatively correlated with the middle, the north, and the west of the plateau. Positive correlation between EASM and precipitation was found in Qaidam Basin and surrounding regions.

Key words: East Asian summer monsoon, South Asian summer monsoon, CRU_TS4.0 data, partial correlation analysis, summer precipitation in Qinghai-Tibetan Plateau
