【摘要】:利用新疆5年的探空數(shù)據(jù)統(tǒng)計各探空站水汽加權(quán)平均溫度T_m與地面溫度T_s的相關(guān)性,通過線性回歸建立各單站T_m模型以及新疆地區(qū)區(qū)域T_m模型。通過比較分析發(fā)現(xiàn):T_m-T_s的相關(guān)性、回歸模型的系數(shù)隨地理位置變化呈現(xiàn)一定的規(guī)律性,相關(guān)性的強弱與T_m-T_s回歸模型的精度不成正比關(guān)系;在新疆地區(qū),單站模型的精度優(yōu)于近年一些文獻建立的幾個重要模型,單站模型的應(yīng)用范圍是有限的,有必要建立區(qū)域模型,新疆區(qū)域模型為:T_m=103.338 8+0.592 3T_s,與前人研究的幾個重要模型相比,區(qū)域模型在新疆地區(qū)計算的T_m內(nèi)外符合精度明顯提高。
[Abstract]:Based on the sounding data of five years in Xinjiang, the correlation between the weighted average temperature of water vapor of each sounding station and the surface temperature of T _ s is calculated. The model of single station T _ m and the regional T _ m model of Xinjiang region are established by linear regression. Through comparative analysis, we found that the coefficients of the regression model show a certain regularity with the change of geographical location, and the correlation is not proportional to the precision of the T_m-T_s regression model. The accuracy of the single station model is better than that of several important models established in recent years. The application scope of the single station model is limited. It is necessary to establish a regional model. The Xinjiang regional model is: 10. 33. 338 8 0.592 3Ts, compared with several important models studied by the predecessors. The accuracy of the regional model calculated in Xinjiang area is improved obviously.
