| 摘 要： | 基于1986-1995年民航广汉机场气象台逐日逐时人工观测资料,利用统计分析,带通滤波方法、功率谱分析和小波分析等方法,分析了广汉机场云的周期性变化特征.结果表明:广汉机场主要受层积云Sc、积云Cu两种低云影响,且二者具有相反的日变化特征,碎层云Fs、雨层云Ns和碎雨云Fn等出现频率很低.广汉机场云量的变化明显具有60...

| Abstract: | Based on the hourly manual observational data from meteorological station at Guanghan airport from 1986 to 1995,the periodic characteristics of low cloud were analyzed by band-pass filtering method,power spectrum analysis method and wavelet analysis method.The results indicate that Guanghan airport is influenced by stratocumulus(Sc) and cumulus(Cu),and the daily variation characteristics of the two clounds are contrary.Other clouds such as stratus fractus(Fs),nimbostratus(Ns) and fracto-nimbus(Fn) seldom ap... |
