Abstract

Based on the precipitation isotopic data of Zhangye station, as well as daily meteorological data, the sub-cloud evaporation variations and their influence on precipitation isotopes with climate change were analyzed. The slope of the Local Meteoric Water Line at ground is lower than that under clouds, and the precipitation is affected by sub-cloud evaporation. Sub-cloud evaporation is most influenced by relative humidity with a negative influence, followed by precipitation amount (negative influence) and air temperature (positive influence). It is higher in the period of 2004–2020 relative to the period of 1986–2003, resulting in richer precipitation isotopes at ground in 2004–2020.

气候变化下张掖云下蒸发对降水同位素的影响

利用张掖站降水同位素资料和逐日气象资料，分析了随气候变化的云下蒸发变化及其对降水同位素的影响。局地大气水线坡度小于云下，降水受云下蒸发影响。云下蒸发受相对湿度的负影响最大，其次是降水量（负影响）和气温（正影响）。2004-2020年相对于1986-2003年更高，导致2004-2020年地面降水同位素更丰富。
