对热态函数位温(θ)、未饱和空气的假相当位温(θse)、饱和空气的假相当位温(θ'se)等的计算分析表明:(1)热态函数廓线θ(p)、θse(p)、θ'se(p)的组合型式和天气过程的发生、发展存在良好的对应性;(2)热态函数廓线型式的演变对天气的进程具有相当的敏感性和吻合性;(3)热态函数廓线组合特征对天气性质具有一定的标志性和指示性。因此,热态函数廓线组合型式和演变特征,具有明显的天气意义,从强天气的预报角度看,这是一条很有开发应用前景的有效途径。
對熱態函數位溫(θ)、未飽和空氣的假相噹位溫(θse)、飽和空氣的假相噹位溫(θ'se)等的計算分析錶明:(1)熱態函數廓線θ(p)、θse(p)、θ'se(p)的組閤型式和天氣過程的髮生、髮展存在良好的對應性;(2)熱態函數廓線型式的縯變對天氣的進程具有相噹的敏感性和吻閤性;(3)熱態函數廓線組閤特徵對天氣性質具有一定的標誌性和指示性。因此,熱態函數廓線組閤型式和縯變特徵,具有明顯的天氣意義,從彊天氣的預報角度看,這是一條很有開髮應用前景的有效途徑。

By calculating and analysing the thermodynamic state functions,potential temperature (θ), po tential pseudo-equivalent temperature of saturated air (θ'se) etc. , the following results are obtained: (1) There is good correspondence between the grouping forms of thermodynamic state functions' profiles ((θ(p) ,θse(p),θ'se(p)) and the occurrence as well as development of weather process; (2) There are considerable sensitivity and accordance between the evolution of the form of the thermodynamic state function profiles and the occurrences as well as development of weather process; (3) The given grouping features of thermodynamic state function profiles have certain signatures and indications of weather characteristics. Consequently, the grouping form and evolution feature of thermodynamic state function profiles have apparent weather sense, especially in the case of severe weather forecast, it is an effective forecast approach with further development and wide application scope.
