摘要

本研究旨在了解地表状态对降水和对流的影响,并以青藏高原为研究对象。该研究考察了能量分布对高原和南部低地的影响,通过WRF模拟比较了两个地区之间的差异。结果表明,地表能分布的变化可以触发对流降水的直接和间接反馈,地表能分布控制着总地表能对降水的贡献。这不仅体现在降水的空间分布、强度和类型上,还体现在云形成的时间和高度上。研究还探讨了特定的微物理过程对降雨的产生和消散的作用。与冷云降水相关的微物理过程受地表能量分布的影响更为显著,呈现负反馈。冷云过程所占比例越高,负反馈越显著。这种耦合状态特征不受区域限制,可以推广。最后,研究了夹带层的边界层变量和微物理变量,发现干耦合区负反馈的存在主要取决于更大的粒子和更强的垂直运动所带来的更强的碰撞和聚集效应。

Surface energy distribution over the Tibetan Plateau and Southern Plain: Impact on convection development in dual coupling regime classification
This study aims to comprehend the impact of surface states on precipitation and convection, with a focus on the Tibetan Plateau. The study examines the effects of energy distribution on the plateau and southern lowlands, comparing differences between the two regions through WRF simulations. The results reveal that changes in surface energy distribution can trigger both direct and indirect feedback on convective precipitation, and that the surface energy distribution controls how the total surface energy contributes to precipitation. This is reflected not only in effects on the spatial distribution, magnitude, and type of precipitation, but also on the timing and height of cloud formation. The study also examines the role of specific microphysical processes to the generation and dissipation of rainfall. The microphysical processes related to cold cloud rainfall are more significantly affected by surface energy distribution and exhibit negative feedback. The higher the proportion of cold cloud processes, the more significant the negative feedback. This coupling state characteristics are not limited by regions and can be generalized. Finally, this study investigated the boundary layer variables and microphysical variables in the entrainment layer and found that the existence of negative feedback in the dry coupling regime mainly depends on the stronger collision and aggregation effects brought about by the larger particles and stronger vertical motion.

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.
