Abstract

Based on daily temperature(maximum and minimum)and daily precipitation at 124 meteorological stations over Northwest China observed by the China Meteorological Administration during the 1960-2009 period, the variability of extreme events of temperature and precipitation over Northwest China in recent 50 years is analyzed and its extreme climatic variation in future is predicted. Eight indices of extreme temperature and six of extreme precipitation are studied. Over the 1960-2009 period, the occurrence of summer days, growing season length, hot night days and maximum temperature days have significantly increased by 2.31, 2.98, 1.07 and 0.45 days/decade, respectively. Over the same period, the regionally averaged occurrence of extreme ice days, consecutive frost days and minimum temperature days have significantly decreased by -2.51,-1.79 and -3.62 days/decade, respectively. The annual temperature range also exhibits a decreasing trend (-0.39℃/decade). With the exception of diurnal temperature range, the other indices correlate with annual mean temperature very well. Precipitation indices about annual maximum with 1-day and 5-day precipitation, consecutive dry days and averaged daily rainfall intensity have no statistically significant increasing trends while the number of heavy precipitation days and consecutive wet days decrease. At the same time, there are significant correlations between annual total precipitation and precipitation extremes except consecutive dry days. In spite of the above-mentioned main trends and correlations in most parts, the differences in spatial distribution and different climatic regions still exist significantly.

Key words： Northwest China; temperature; precipitation; climate extremes
