摘要
利用台站加密观测资料、卫星云图和NCEP再分析资料，对2012年1月8～10日华北地区一次持续性大雾天气过程的大尺度天气背景、热动力结构及其演变特征进行了计算和分析，揭示了该气象过程的高低空特征。
Based on auto-observation data, satellite cloud images and NCEP 1°× 1° reanalysis data, a persistent heavy fog process in North China that occurred from January 8th to 10th, 2012 was discussed. The circulation background, thermal and dynamic structure and evolution characters of the sustained heavy fog were calculated and analyzed to reveal characteristics of this process.
