中文摘要: 受静稳天气影响,2017年1月3—6日我国华北、黄淮、长江中下游以及华南等中东部地区出现了大范围的持续性大雾天气,其中济南70 m以下的低能见度天气持续了6 h之久,最低能见度只有51 m。利用布设在山东省气象局院内的FM-120雾滴谱仪观测的微物理资料、自动气象站加密观测等资料,分析了此次浓雾天气过程的微物理结构,讨论了雾在4次“发展—减弱”过程中的主要特征,研究了雾在不同发展阶段以及爆发性增强期间的演变规律,探讨了雾的成因以及爆发性增强的原因。
Abstract:A large-scale continuous heavy fog weather occurred in the central and eastern regions of China, including North China, Huanghuai Region, the middle and lower reaches of the Yangtze River, and South China during 3-6 January 2017. The low visibility below 70 m in Jinan lasted for more than 6 h and the minimum visibility was only 51 m. Based on the data from fog droplet collector and automatic weather station, the microphysical structure of the fog was analyzed, the main characteristics of fog in four “development-weakening” subprocesses were discussed, the evolution characters in different development and burst reinforcement phases of the fog were studied, and the causes of the dense fog and burst reinforcement were also discussed in this paper.
