摘　　要： 本文采用1999～2002年福州民航站白天逐时气象能见度的观测资料,利用统计和小波分析等方法,对该站气象能见度的日变化、季节变化以及季节内的变化等气候特征进行了分析.结果表明,其能见度日变化呈白天的早、晚时段较低,午后达到最高.能见度的季节变化呈冬、春季的较低,夏、秋季的较高,且存在着"6月份突变"的特性.其季节内变化主要以准两周(10～20d)振荡和30～60d准周期的振荡为主,且季节内振荡可能与东亚季风的季节内振荡密切相关. Using the hourly diurnal meteorological visibility data of Fuzhou Airport from 1999 to 2002, the diurnal, seasonal and intraseasonal variations of the visibility are studied based on statistical method and wavelet analysis. Diurnal variations shows that the visibility is low in the morning and evening, while reaches its maximum after noon. Seasonal cycle of the visibility is that low visibility occurs in winter and spring, while high visibility in summer and autumn, with a sudden jump in June. Intraseasonal variation includes quasi-biweekly(10～20d) oscillation and 30～60d madden-julian oscillation(MJO), which maybe related to the intraseasonal oscillation of the East Asian monsoon.
