| 摘 要： | 利用中国710个站(青藏高原72个站)的气温和降水资料,分析了青藏高原的气候特征及与中国区域气候异常的联系。结果表明：中国多雨日区域随季节分布大致可以分为华南区、华南一青藏高原东南部区、青藏高原区以及华西区共5个区域,多雨日区自东向西移动。青藏高原东南地区降水特征呈双峰型,西北呈单峰型;西南部存在明显的“高原梅雨”、伏旱和秋雨。林芝地区的遥相关分析表明：冬季温度与青藏高原同期温度为正相关,与我国其它大部分地方为负相关;夏季降水与青藏高原南部和长江中下游地区同期降水为正相关,与高原北部同期降水呈反相关关系;冬季温度与黄河到长江流域之间区域夏季降水呈反相关关系。 |

| Abstract: | The relationship between the climatic characteristic over Qinghai-Xizang Palteau and Chinese abnormal climate is studied by using the temperature and precipitation data of 710 stations (72 stations in Qinghai-Xizang Plateau). The results show that the areas of more rain days can be divided into five areas, namely the South China, South China-Southeast of Qinghai-Xizang Plateau, Qinghai-Xizang Plateau and West China, and the more rain areas more than 5 rain days in each decad move from east to west of China. The annual precipitation feature in Southeast of Qinghai-Xizang Plateau are double peak values, and in Northeast, for single peak value, but there are obvious "Plateau rainy period", summer drought and autumn rainfall in Northwest of Qinghai-Xizang Plateau. The analysis of teleconnetion in Linzhi shows that the correlation coefficient between the winter temperature in Linzhi and the one at the same period in Qinghai-Xizang Plateau is positive, and the other regions are negative. The correlation coefficient between summer precipitation in Linzhi and the one at the same period in South of Qinghai-Xizang Plateau and in the mid-and-lower reaches of Changjiang River is positive, and in North of Qinghai-Xizang Plateau, for negative. The correlation between winter temperature at Linzhi and summer precipitation of regions from Yellow River to Changjiang River is negative. |
