JiSMART2021—062: Impact of Climate Change on Evaporation of Near-Surface Dew in the City of Changchun, China

Abstract

With the global climate change, the shortage of water resources is also a common challenge facing the world. Dew is an important source of condensed water resources and humidity, and its development and utilization has gradually been taken seriously. In this study, by analyzing the correlation law between the evaporation intensity of dew and meteorological factors in 2019, the influencing factors of evaporation of near-surface dew were found. The results showed that the dew intensity of Changchun City was significantly positively correlated with wind speed and temperature during the experimental period (P<0.05), and negatively correlated with relative humidity (P<0.05).
