| 摘 要： | 本文利用40a逐日降水与气温资料，分析了西藏地区降水量、气温的年变化和年代际变化特征，讨论了气温与降水量的相关关系。结果表明：近几十年来，西藏年平均气温、降水量有明显上升的趋势；气温是影响西藏地区降水量的重要因子之一。绝大多数月份的月平均降水量与前期气温有很好的相关关系，可作为月平均降水量预报的参考依据。 |
| 关 键 词： | 西藏 气温 降水量 年代际变化 相关分析 |

| Abstract: | In this paper, annual and interannual variation characteristics of precipitation and air temperature of Tibet region were analyzed, correlativity of air temperature and precipitation was discussed by using 40 years data of day-to-day precipitation and air temperature. The results showed: mean annual air temperature and precipitation of Tibet region had obvious uplifted trends in several decades; air temperature was one of the important factors which influence precipitation of Tibet region. Monthly mean precipitation and foregoing air temperature had nicer correlativity in most of months, and air temperature was regarded as reference in prediction of monthly mean precipitation. |
