【摘要】：通過以系留氣球和探空氣球為平臺的方式,搭載溫度脈動儀在戈壁地區(qū)對大氣折射率結(jié)構(gòu)常數(shù)開展長期測量。對獲取的實驗數(shù)據(jù)開展統(tǒng)計分析,探討了在白天與夜間折射率結(jié)構(gòu)常數(shù)的平均情況、高度分布、偏度與峰度、季節(jié)的強弱特性等四個方面的內(nèi)容,結(jié)果表明:在測量地區(qū),隨高度分布的大氣折射率結(jié)構(gòu)常數(shù)在白天和夜間的算術(shù)平均值和對數(shù)平均值的比值會有較大的差異,并且白天和夜間的對數(shù)平均值和標(biāo)準(zhǔn)差系數(shù)隨高度分布各有其特點,表現(xiàn)在隨高度整體減小的同時會有起伏出現(xiàn),尤其是夜間;白天和夜間的偏度與峰度主要表現(xiàn)出右偏和尖峰特性,在高度分布上有所不同;季節(jié)變化對湍流的強弱分布產(chǎn)生明顯影響,集中體現(xiàn)在中性湍流和弱湍流分布情況隨高度發(fā)生交互變化。
[Abstract]:The atmospheric refractive index structure constant is measured in the Gobi area by means of the mooring balloon and the sounding balloon as the platform, and the temperature pulsator is used to measure the atmospheric refractive index structure constant in the Gobi area for a long time. The statistical analysis of the obtained experimental data is carried out, and the four aspects of the refractive index structure constant in the daytime and at night, the distribution of height, the skewness and kurtosis, the intensity and weakness of the season, are discussed. The results show that: in the measured area, The ratio of arithmetic mean and logarithmic average of atmospheric refractive index structure constant with height distribution will be different between day and night, and the logarithmic mean value and standard deviation coefficient of day and night have their own characteristics with height distribution. The deviation and kurtosis of day and night mainly show the characteristics of right deviation and peak, which are different in height distribution. Seasonal variation has obvious influence on the intensity and weak distribution of turbulence, mainly reflected in the interaction between the distribution of neutral turbulence and weak turbulence with height.
