摘　　要：在地面气象观测业务中一般采取人工观测判断结冰现象是否发生。为了提高结冰观测的工作效率,结冰自动化观测已经成为必然的趋势。文章介绍一种新的结冰自动化观测装置,通过检测结冰过程中由于潜热释放引起的温度突变上升过程,判断结冰现象的发生,实现结冰自动化观测。结合结冰温度观测数据对结冰过程中各个阶段特征进行分析,并与人工观测的结果进行对比,结果表明结冰自动化观测装置能够比较准确地实现结冰现象的检测,具有一定的实际应用价值。In the ground meteorological observation, it generally takes artificial observation to judge wheth er icing phenomenon occurs. In order to improve the efficiency of icing observation, automation of icing observation has become an inevitable trend. This paper introduces a new automatic observation device for icing through detecting the sudden rise process of temperature that is caused by latent heat release in the icing process, and judges the occurrence of icing phenomenon to realize the automation of icing observa tion. Combined with temperature observation data, characteristics of each stage in the icing process are an- alyzed as well. Compared with the artificial icing observation results, it is concluded that the automation observation device for icing can accurately observe icing phenomenon.
