摘要
为了获得地理位置上随高度变化的大气温度统计特性,基于有限的对流层大气温度观测数据,根据谐波规律给出了大气温度的统计均值和方差,并采用观测数据的相关性矩阵和随机变量,建立了对流层大气温度统计模型。根据模型和方法,统计分析后可以得到对流层大气温度特性,经过与观测数据统计参数比较,验证了模型和方法的有效性。
In order to obtain the statistically characteristics of temperature with altitude at specific location,based on the limited measured data of atmospheric temperature at Troposphere,a statistical model of atmospheric temperature is proposed,in which the mean and standard deviations are provided through harmonic analysis,whereas the correlation matrix and random variable are given from measured data.Then the statistical characteristics of atmospheric temperature at Troposphere can be calculated,and the effectiveness of the proposed methods is verified through comparison with results.
