Simulation and estimation of future precipitation changes in arid regions: a case study of Xinjiang, Northwest China

Precipitation is critical for maintaining the stability of an ecosystem, especially in arid regions. This study primarily focuses on climatic changes during present (from 1985 to 2005) and future 2040 2059) periods Xinjiang, Northwest China. In this study, Weather Research Forecasting model implemented Xinjiang efficiently predict climate. Moreover, National Climate Center Community System Model version 4 employed mid-21st century under representative concentration pathways 4.5 8.5 (RCP4.5 RCP8.5, respectively). Our results indicate that amount annual precipitation will increase RCP4.5 RCP8.5 mountainous areas. The predicted be much smaller than RCP4.5, except Southern Xinjiang. increasing implies current humid warm conditions persist, thereby further indicating still currently suffering from a dry largest seasonal occur spring summer Tianshan Northern whereas phenomenon winter addition, it daily heavy events more frequently various subregions although light rain remain dominant. Finally, relative humidity closely related precipitation.
