Abstract

In this article, we provide strong evidence for moisture feedback playing an important part in China’s precipitation. Due to the fact that China’s water scarcity has a huge impact on the economy and society, it is not only a problem for the country itself but could become a problem for the whole world in the near future. Most research in the past focused on improving water use efficiency, which are short term solutions. An appropriate use of moisture recycling data could however be a prime tool in solving long term water scarcity problems. Correlation coefficients and the continental precipitation multiplier are methods to quantify the relation between evaporation and precipitation in different areas. These results can be used in a simple forecasting model, enabling better insights in the precipitation. The results show a high correlation coefficient between Eurasia and China with 51% of the precipitation in China being of continental origin.
