【摘要】 利用青岛市2005~2007年的气象资料,通过统计学和小波分析的方法分析了青岛市水平能见度的变化特征和气象影响因子,发现青岛市能见度有明显的日、天气尺度、准双周、季节和半年的振荡周期,其变化特征和温度、相对湿度、风向、风速、地面气压、海雾以及边界层高度等要素都存在一定的关联。
【Abstract】 Using meteorological data in Qingdao from 2005 to 2007,analyze variation characteristics of visibility and meteorological influence factors,it is found that ① There are distinctly daily,2-10 days,quasi-two-week,seasonal and half-year variations of visibility by statistical method and wavelet analysis method.② The variation characteristics of visibility in Qingdao is related with temperature,relative humidity,wind direction,wind speed,surface pressure,sea fog and the height of ABL by studying the characters of these variations.
