Abstract

Based on the CLoud, Albedo and RAdiation dataset, AVHRR-based, version 2 (CLARA-A2), Tropical Rainfall Measuring Mission 3B43 (TRMM-3B43), and European Centre for Medium-Range Weather Forecasts Reanalysis v5 (ERA5) reanalysis data, the potential cloud precipitation capacity (PCPA) of typical regions in China is compared, and the relationship between impact factors and PCPA is discussed. Results have suggested that the Tarim Basin (TB) has scarce cloud water resources, while cloud water path (CWP) values are higher in South China (SC) and Sichuan Basin (SB) under the influence of the East Asian monsoon. Moreover, different typical regions of China exhibit varying dependencies on the ice water path (IWP) and liquid water path (LWP). There is a strong correlation between the IWP and precipitation in the Tibet Plateau (TP), Northeast China (NE), SC, and SB. The precipitation in TB demonstrates a more pronounced correlation with the LWP. Through a comparison of the correlation between PCPA and influencing factors in different typical regions of China, it is found that convective available potential energy (CAPE), surface latent heat flux (SLHF), surface sensible heat flux (SSHF), and 0–3 km relative humidity (RH) exhibit stronger correlation with PCPA than 2 m temperature (T2m) and 2–5 km vertical wind shear (SHEAR). Further investigation revealed that the joint effect of CAPE, RH, and SLHF has a pronounced effect on PCPA, particularly during spring and autumn. Additionally, the PCPA of TP exhibits significant dependency on the joint effect of these three influential factors. Furthermore, the ratio of LWP to IWP (RLI) also affects PCPA. In spring and autumn, the PCPA of TB and NC exhibits a positive correlation with RLI, whereas the PCPA of TP, SC, NE, and SB shows a negative correlation with RLI. In summer, the PCPA of TB and SC exhibits a notably negative correlation with RLI. This study deepens the understanding of the formation mechanism of cloud precipitation in typical regions of China, provides the basis for climate forecast and improves the accuracy of weather forecast.

中国典型地区的潜在云降水能力
基于云、反照率和降水数据集--基于高级甚高分辨率辐射计的第2版(CLARA-A2)、热带降雨测量任务3B43(TRMM-3B43)和欧洲中期天气预报中心再分析v5(ERA5)再分析数据,比较了中国典型地区的潜在云降水能力(PCPA),并讨论了影响因子与PCPA之间的关系。结果表明,受东亚季风影响,塔里木盆地云水资源匮乏,而华南和四川盆地的云水路径(CWP)值较高。此外,中国不同典型地区的冰水路径(IWP)和液水路径(LWP)也表现出不同的依赖性。冰水路径与西藏高原(TP)、东北地区(NE)、华南地区(SC)和华北地区(SB)的降水量之间存在很强的相关性。而 TB 的降水与 LWP 的相关性更为明显。通过比较中国不同典型地区 PCPA 与影响因子的相关性,发现对流可用势能(CAPE)、地表潜热通量(SLHF)、地表显热通量(SSHF)和 0-3 km 相对湿度(RH)与 PCPA 的相关性强于 2 m 温度(T2m)和 2-5 km 垂直风切变(SHEAR)。进一步研究发现,CAPE、相对湿度和 SLHF 的共同作用对 PCPA 有明显影响,尤其是在春季和秋季。此外,TP 的 PCPA 与这三个影响因子的共同作用有显著的相关性。此外,LWP 与 IWP 之比(RLI)也会影响 PCPA。在春季和秋季,TB 和 NC 的 PCPA 与 RLI 呈正相关,而 TP、SC、NE 和 SB 的 PCPA 与 RLI 呈负相关。在夏季,TB 和 SC 的 PCPA 与 RLI 呈明显的负相关。该研究加深了对我国典型地区云降水形成机理的认识,为气候预测提供了依据,提高了天气预报的准确性。

期刊介绍: The journal publishes scientific papers (research papers, review articles, letters and notes) dealing with the part of the atmosphere where meteorological events occur. Attention is given to all processes extending from the earth surface to the tropopause, but special emphasis continues to be devoted to the physics of clouds, mesoscale meteorology and air pollution, i.e. atmospheric aerosols; microphysical processes; cloud dynamics and thermodynamics; numerical simulation, climatology, climate change and weather modification.
