| 摘 要： | 在塔塔尔斯基理论模式框架下, 使用全国81个气象站1986~1995年10年探空资料计算了各测站海拔高度上的Fried参数r0。统计结果表明, r0的年平均值的分布与相应地形分布基本一致, 大气湍流的差异对局部地区的r0有着明显的影响。月平均r0的高值中心区存在明显的季节变化, 可能与相应副热带急流的季节变化有关。 |

| Abstract: | Based on the standard meteorological radiosonde data in the years of 1986 to 1995, the Fried parameter r 0 is calculated by means of the theoretical model of Tatarski over 81 meteorological stations in China. The geographical distribution of the annual mean r 0 at ground is in accordance with the topographical distribution basically. The effect of the variation of atmospheric turbulence on the local distribution of r 0 is apparent. The locations of the high monthly mean r 0 centers are different in different seasons and all these differences are related to the seasonal behavior of the subtropical jet stream possibly. |
