Abstract

The Earth’s atmospheric interface is highly vulnerable to anthropogenic aerosol pollution and changes caused by numerous industrial and allied sectors. The boundary layer aerosol emissions interact directly or indirectly with the dynamics and microphysical processes, impact cloud properties, precipitation accumulations, and subsequently affect socio-economic growth. The primary objective of this study is to synthesize the aerosol-convection-precipitation interactions concerning atmospheric microphysics and identify the modern methods to explore such dynamics. The secondary objective of this study is to understand and analyze the scientific literature with a bibliometric analysis to find the significant theme of influence from the scientific literature. The results highlighted the main and critical trends in aerosol research and reveal that the research interest seemingly improved in the past 5 years with an annual scientific growth rate of approx. 6%. It is evident from a plethora of relevant research findings that aerosol loading in the atmosphere up to a certain effective droplet concentration may increase the precipitation, however, further increment in aerosol concentration will decrease the precipitation efficiency. Regional feedback mechanisms (boundary layer, radiative etc.) play a pivotal role in governing aerosol and convective precipitation dynamics. The combination of satellite observations from space and ground-based (in-situ) measurements and climate models offers a practical possibility for resolving the complexity in cloud micro-phenomenology.

探索气溶胶与对流降水之间动力学的现代方法:评论
地球的大气界面极易受到人为气溶胶污染以及众多工业和相关部门造成的变化的影响。边界层气溶胶排放直接或间接地与动力学和微物理过程相互作用,影响云的特性和降水累积,进而影响社会经济增长。本研究的主要目的是综合气溶胶-对流-降水之间有关大气微物理的相互作用,并确定探索这种动力学的现代方法。本研究的次要目标是通过文献计量学分析来了解和分析科学文献,从科学文献中找到具有重要影响的主题。研究结果强调了气溶胶研究的主要和关键趋势,并揭示了过去 5 年中研究兴趣似乎有所提高,年科学增长率约为 6%。大量相关研究结果表明,大气中的气溶胶负荷达到一定的有效液滴浓度时,降水量可能会增加,但气溶胶浓度的进一步增加会降低降水效率。区域反馈机制(边界层、辐射等)在控制气溶胶和对流降水动态方面起着关键作用。空间卫星观测、地面(现场)测量和气候模式的结合为解决云微观现象学的复杂性提供了切实可行的可能性。

期刊介绍: Dynamics of Atmospheres and Oceans is an international journal for research related to the dynamical and physical processes governing atmospheres, oceans and climate. Authors are invited to submit articles, short contributions or scholarly reviews in the following areas: •Dynamic meteorology •Physical oceanography •Geophysical fluid dynamics •Climate variability and climate change •Atmosphere-ocean-biosphere-cryosphere interactions •Prediction and predictability •Scale interactions Papers of theoretical, computational, experimental and observational investigations are invited, particularly those that explore the fundamental nature - or bring together the interdisciplinary and multidisciplinary aspects - of dynamical and physical processes at all scales. Papers that explore air-sea interactions and the coupling between atmospheres, oceans, and other components of the climate system are particularly welcome.
