The authors are retracting this Article.

In this study, we used RegCM to downscale the ERA40 and NCEP climate data in the Xinjiang area, and then compared the simulated data with extrapolated data from CRU.

Extrapolated data were used because using observational data would have led to poor performance of the model, RegCM. As a result, conclusions reported in the paper – increasing precipitation in South Tianshan, and a decreasing trend in the north – are unsupported, and are misleading to the research community and the public. Therefore, we are retracting this article. We apologize for the inconvenience caused.

All authors agree with the retraction.
