| 摘 要： | 通过湍流气象探空仪测量湍流廓线及常规气象参数并同时监测地面温湿变化,得到长春地区夏季湍流及温湿度的垂直分布状况.对测量结果分析发现,所测湍流廓线较好地符合适用于中纬度地区的Hufnagel-Valley湍流模式,由此计算出的大气相干长度γ0平均值为5.5 cm,与HV模式相适应.在湍流气象探空仪双通道工作情况下,采用不同的微温探头间距对折射率结构常数进行测量,发现两种距离下湍流强度随高度的变化趋势基本相同,在10 km下的较强湍流区0.5 m间距测量结果稍大于1 m的情况,由此计算的γo相差不大,1 m测量结果相对起伏较大,细节明显.

| Abstract: | The vertical distributing of turbulence,temperature and humidity were obtained in Changchun city by the detecting of turbulence profile using meteorologic radiosonde for turbulence and general meterological parameters at the same time.Results show that the turbulence profile was finely accorded with the Hufnagel- Valley model that is widely used in mid-latitude area.The mean of atmospheric coherence length is 5.5 cm. It's also adapt to HV model.When the meteorologic radiosonde works in double channels;refra... |
