一次槽前“干”对流背景下阵风锋天气过程分析
引用次数: 0
Abstract
对2015年8月23日发生在陕西关中的一次伴有阵风锋的强对流天气过程的不稳定度条件\，卫星云图和雷达资料进行分析，结果表明：本次强对流天气过程虽然发生在槽前，但垂直环境配置为“上干下湿”，属于槽前“干”对流，850 hPa的切变线为强对流提供了初始扰动，地面辐合线触发了强对流天气的发生；两条阵风锋均出现在对流云团边缘TBB梯度最大的区域内、对流有效位能剧烈释放时；另外，两条阵风锋的相向运动，导致两条阵风锋之间强对流单体的产生。当强对流云团与阵风锋叠加时，一方面，二者相互抑制，互为削弱，阵风锋很快消散；另一方面，与阵风锋相联系的对流云团中因为有新的对流单体补充又迅速发展，产生更剧烈的强对流天气。一次槽前“干”对流背景下阵风锋天气过程分析

期刊介绍：
Plateau Meteorology is a bimonthly academic journal with ISSN 1000-0534 and CN 62-1061/P since 1982. The journal is supervised by the Chinese Academy of Sciences, sponsored by the Northwest Institute of Ecology and Environmental Resources of the Chinese Academy of Sciences, and published by Science Press. It is dedicated to disseminating the knowledge of plateau meteorological science and promoting the development of plateau atmospheric science, aiming to meet the needs of plateau atmospheric scientific research and meteorological operations, as well as to promote the development of atmospheric science and related disciplines and the growth of talents. The journal pays special attention to new results, new ideas and new progress in the disciplines of Qinghai-Tibetan Plateau Meteorology and Mountain Meteorology, and covers the fields of weather and climate theory, observation, forecast prediction methods, global climate change, atmospheric physics, atmospheric chemistry and atmospheric lightning. Priority is given to the publication of innovative research results funded by the National Knowledge Innovation Project, National Major Research Projects and the National Natural Science Foundation of China. The journal is equipped with columns of academic papers, short essays, research briefs, academic discussions and comprehensive reviews, and is aimed at scientific and technical personnel in meteorology and related fields, operational personnel, and teachers and students of higher education institutions. Plateau Meteorology is included in several databases, including Chinese Core Journals, Chinese Science Citation Database, China Science and Technology Papers and Citation Database (Core Board), RCCSE Chinese Core Academic Journals, Chinese Academic Journals (CD-ROM), Scopus Database, EBSCO (USA), and Japan Science and Technology Agency (JST) Database.
