| Abstract: | In this paper, the monthly precipitation and temperature data collected at 7 stations in the Ili River Basin from 1961 to
2007 were analyzed by means of simple regression analysis, running mean, db6 wavelet function and Mann-Kendall test. This
study revealed the characteristics of climate change and abrupt change points of precipitation and temperature during different
time scales in the Ili River Basin within the past 50 years. The results showed that the precipitation increased from the
mid-1980s until 2000 and has continued to increase at a smaller magnitude since 2000. Over the studied period, the precipitation
increased significantly during the summer and winter months. The temperature increased greatly in the late 1980s, and has
continued to show an increasing trend from the year 2000 to present. The temperature increases were most significant during
the summer, autumn and winter months. In terms of different geographies, the temperature increase was significant during the
winter in the plains and hilly regions; the increase was also significant during autumn in the intermontane basins. The climate
change trends in the Ili River Basin were consistent with the changing trends of the North Atlantic Oscillation and the plateau
monsoon. |
