Abstract
AbstractPrecipitation recycling plays a key role in the hydrological cycle process. The precipitation recycling ratio is a diagnostic measure for interactions between land surface hydrology and regional climate. To demonstrate the influence of the hydrological cycle on the climate of an arid area in northwest China, the authors studied the precipitation recycling ratio and the characteristics of the hydrological cycle in the Tarim River basin, which includes characteristics of water vapor transportation flux divergence and convergence, evaporation and its spatial distribution, and the spatial distribution of precipitation recycling ratio. The results suggest that there is about 14% of annual precipitation coming from the evaporation of the Tarim River basin, and 86% of advected precipitation coming from the surrounding external areas to the region. It is lower than other world famous river basins such as the Amazon, the Mississippi River, the Yellow River, and the Yangtze River basins. The recycling is ac...
