摘　　要：该文讨论了气象能见度的突变特征及其在预报上的应用，研究表明，可用计算中空以上的变温分布和云量变化来诊断气象能见度。Application of catastrophe theory to visibility forecast is discussed.The results show that the low visibility can be estimated by computing the change distribution of middle upper air temperature and air pressure.Furthermore ,to some extent the mathematical symbols alternation of the middle upper air temperature changes and the air pressure changes indicate the formation or the elimination of low visibility.

关 键 词：气象能见度 气象预报 变化特征 云量变化
