塔克拉玛干沙漠地区温压湿分布规律研究

Distribution Rules of Temperature, Humidity, Atmospheric Pressure in Taklimakan Desert

根据塔克拉玛干沙漠周围近 2 0个气象测站 3 6a冬季 ( 1月 )、夏季 ( 7月 )平均气温、气压、相对湿度和塔克拉玛干沙漠地区 6个短期观测站近 10 a的有关气象资料 ,对该地区冬、夏季平均温度、相对湿度、气压分布规律进行了系统研究 ,建立了冬季 ( 1月 )平均温度、夏季 ( 7月 )平均温度预测方程 :T1 =3 1.0 0 69-0 .2 0 3 8λ-0 .45 5 6φ-0 .0 0 3 H;T7=5 7.0 15 5 -0 .64 2 5 φ-0 .0 0 5 5 H。同时 ,在此基础上 ,应用统计学导出的正态分布和β分布概率模式 ,预测了塔克拉玛干沙漠周围各测站冬夏季不同概率的设计值 ,并进行了χ2 检验 ,通过率 10 0 %。以预测方程和概率模式揭示了塔克拉玛干沙漠地区冬夏季温、压、湿分布规律。

Based on the meterological data of temperature, pressure and relative humidity (January and July) from 20 stations nearby Taklimakan Desert with 36 a series data and 6 stations within the desert with 10 a series data, this paper has systematically analyzed their distribution rules, and built up the predicting equations for average temperature of January and July:\%T\-1=31.0069-0.2038λ-0.4556φ-0.003H;T\-7=57.0155-0.6425φ-0.0055H\%. Meanwhile, the designed values of temperature under different possibilities are obtained by using normal distribution and \%β\% distribution models. The chi squared test proved the passing rate is 100%.
