利用藏北高原西藏那曲地区6个气象站1971—2011年逐年月降水量、降水日数资料,通过线性倾向估计、多阶曲线模拟和Mann-Kendall法等气候统计学诊断方法,对近41年来降水趋势变化的地理分布以及年内、年际变化规律进行了分析,并进行突变检测。结果表明:近41年来,那曲地区年降水量总体呈增加趋势,经历了由偏少到偏多的2个周期;降水增加夏季最明显,各站在6.48~20.40 mm/(10 a),冬季变化很小;日降水量≥0.1 mm日数年际周期变化与降水量变化基本一致,增加趋势空间分布呈东南向西北递减形势;自1996年开始各站降水增加趋势明显,1999年发生气候突变可能性较大。

This paper investigated the spatial and temporal distribution of precipitation during 1971 to 2011 in Nagqu Prefecture of Northern Tibet Plateau,China based on the monthly precipitation and the annual number of precipitation days at 6 meteorological stations and climatic statistic methods,including linear tendency evaluation,multistage curve simulation and the Mann-Kendall test. Results show that annual precipitation exhibits increasing trend in the past 41 years which experienced two periods from less precipitation to more precipitation. The increase of precipitation in summer is quite obvious with 6.48 to 20.40 mm increment per decade while the variation is pretty small in winter. The interannual distribution of number of days with daily precipitation larger than 0.1 mm is basically has same variation with the annual precipitation. The spatial distribution of precipitation decreases from the southeast to the northwest parts of Tibet. The precipitation start to increase from 1996 at each meteorological stations and it has greater possibility of abrupt climate change in 1999.
