Abstract

Abstract: Using ERA-interim reanalysis data and night light remote sensing data, the quantitative relationship between spatial-temporal evolution of relative humidity（RH） and urbanization level was researched in the Beijing-Tianjin-Hebei region in 1993, 1997, 2001, 2005, 2009 and 2013. The results showed that the proportion of dry islands in the Beijing-Tianjin-Hebei region showed a trend of increasing over time, which was positively correlated with the rate of land urbanization. The spatial correlation between the average relative humidity and urbanization level showed negatively correlated in 2005, with a correlation coefficient of -0.730, which was below the significance level of 0.01, and the distribution of RH in spatial was affected by the urbanization level. The correlation between average relative humidity and urbanization level at different grid sizes increased firstly and then weakened with grid size increasing, and the correlation between average relative humidity and urbanization level reached the maximum （above 0.700） at 100 km grid size.

Key words: ERA-interim reanalysis data, night light, grid, relative humidity, urbanization, correlation
