Abstract

The temperature for cloud glaciation importantly determines the initialization of precipitation and lifetime of clouds. The role of anthropogenic pollutants as ice nucleating particles (INPs) to determine the cloud glaciation remains uncertain. In this study, based on satellite radar and lidar observations, the clouds either in pure liquid or mixed-phase with liquid top were statistically analyzed over China during 2006–2019, to obtain the transition freezing temperature (T*) of cloud top where mixed-phase becomes more frequent than pure water, with further validation by the aircraft in situ measurements. Anthropogenic pollution was observed to raise T* up to −9°C, significantly increasing it by approximately 5°C per unit of aerosol optical depth. The results provide regional-scale evidence that anthropogenic pollutants act as efficient INPs, increasing the freezing temperature of mixed-phase clouds.

人为污染导致中国上空云层冻结温度升高
云冰川的温度在很大程度上决定了降水的初始化和云的寿命。作为冰核粒子(INPs)的人为污染物对云冰川化的决定作用仍不确定。本研究基于卫星雷达和激光雷达观测数据,统计分析了2006-2019年中国上空的纯液态云或云顶液相混合云,得出云顶液相混合云比纯水云更频繁出现的云顶过渡冰点温度(T*),并通过飞机原位测量进一步验证。观测到人为污染使 T* 升高至 -9°C,每单位气溶胶光学深度显著升高约 5°C。这些结果提供了区域尺度的证据,证明人为污染物可作为有效的 INPs,提高混合相云的冻结温度。

期刊介绍: Geophysical Research Letters (GRL) publishes high-impact, innovative, and timely research on major scientific advances in all the major geoscience disciplines. Papers are communications-length articles and should have broad and immediate implications in their discipline or across the geosciences. GRLmaintains the fastest turn-around of all high-impact publications in the geosciences and works closely with authors to ensure broad visibility of top papers.
