【摘要】 根据新时代科学基金改革要求，2020年国家自然科学基金委员会调整了大气科学学科申请代码，D0505大气物理学是分支学科板块中的二级申请代码之一。本文介绍了D0505大气物理学二级申请代码的总体框架和下设的边界层大气物理学与大气湍流、云降水物理学、气溶胶物理及气溶胶—云相互作用、大气光学与大气辐射、大气电学与大气声学和中高层大气物理学等6个研究方向及其关键词，指出D0505与其他相关二级申请代码的异同，并统计分析了近5年（2017～2021年）科睿唯安Web of Science数据库上不同方向关键词对应的文献发表情况，探讨了不同研究方向的发展态势。通过系统梳理研究方向及关键词，有助于科研人员在项目申请过程中准确的选择申请代码、研究方向和关键词，提升智能辅助指派效率。更多还原

【Abstract】 In 2020, the National Natural Science Foundation of China modified the application code of the atmospheric sciences discipline and established 15 secondary disciplines according to the reform needs of the new era. D0505 is one of the secondary application codes for the subdisciplines. This paper introduced the general framework of the secondary application code, its six research directions(boundary layer atmospheric physics and turbulence, cloud and precipitation physics, aerosol physics and aerosol–cloud interactions, atmospheric optics and radiative transfer, atmospheric electricity and acoustics, and physics of the middle atmosphere), and their keywords, as well as the similarities and differences between D0505 and other relevant secondary application codes. The paper then examined possible research patterns and trends by analyzing the publication records under each keyword in different research directions from the Web of Science database in the last five years(2017–2021). This paper will assist fund candidates in correctly selecting application codes,research directions, and keywords.更多还原
