Precipitation effects on temperature—A case study in China

Abstract

To discover the mechanism of the continuous summer temperature decline in certain regions against significant global warming, 456 national meteorological observational stations with long term of observed daily temperature and precipitation data were applied to analyze the relationship between precipitation and temperature. Results show that there is a significant negative correlation between precipitation and temperature, indicating that precipitation influences temperature significantly: the more the precipitation, the lower the temperature, and vice versa. The precipitation effect on temperature can reasonably interpret the typical summer temperature in Southwest China and can partly explain why global warming is more significant in winter than in summer and more significant in higher latitude areas than in lower latitude.
