Abstract (English): Antarctic clouds and their vertical structures play a significant role in influencing the regional radiation budget and ice mass balance; however, substantial uncertainties persist. Continuous monitoring and research are essential for enhancing our understanding of these clouds. This study presents an analysis of cloud occurrence frequency and cloud-base heights (CBHs) at Zhongshan Station in East Antarctica for the first time, utilizing data from a C12 ceilometer covering the period from January 2022 to December 2023. The findings indicate that low clouds dominate at Zhongshan Station, with an average cloud occurrence frequency of 75%. Both the cloud occurrence frequency and CBH distribution exhibit distinct seasonal variations. Specifically, the cloud occurrence frequency during winter is higher than that observed in summer, while winter clouds can develop to greater heights. Over the Southern Ocean, the cloud occurrence frequency during summer surpasses that at Zhongshan Station, with clouds featuring lower CBHs and larger extinction coefficients. Furthermore, it is noteworthy that CBHs derived from the ceilometer are basically consistent with those obtained from radiosondes. Importantly, ERA5 demonstrates commendable performance in retrieving CBHs at Zhongshan Station when compared with ceilometer measurements. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 摘 要: 南极云在影响区域辐射收支和冰盖质量平衡方面起着重要作用。 然而, 气候模式中对于南极云的描述仍然存在非常大的不确定性。 持续观测和研究南极云对于增强我们对云的理解至关重要。 本研究首次利用 2022 年 1 月至 2023 年 12 月期间国产 C12 型激光云高仪的数据, 对东南极中山站的云发生频率和云底高度分布特征进行了分析。 研究结果表明, 中山站以低云为主, 平均云发生频率为 75%。 云发生频率和云底高度分布都呈现出明显的季节变化特征。 具体来说, 冬季云发生频率高于夏季, 同时冬季的云层可以发展到更高的高度。 在南大洋, 夏季云发生频率超过中山站, 伴随着更低的云底高度和更大的消光系数。 此外, 激光云高仪观测的云底高度与无线电探空仪获得的云底高度结果基本一致。 对比 ERA5 与激光云高仪的结果, 发现 ERA5 云底高度产品在中山站低云场景下表现较好, 但高云云底会被显著低估。 [ABSTRACT FROM AUTHOR]
