For understanding the workability and precision of these prediction equations, at first this study not only simulates the MHs of Taipei, Taichung, Kaoshung cities and Kao-ping area but also compares these results with meteorological models of CLAMET and TPAQM. And the comparisons show the high correlation (up to 0.8) between them. When the results of MH prediction equations model are compared with TPAQM, they get higher or lower values than TPAQM. The reasons are that Holzworth method can not concern about the warm and cold advections effect and the upper air data used do not get enough finer space-spread. About the results spread on the domain of my model, they show more different MH fields between the land and the sea around and get more sharply change of the land MHs on daytime than TPAQM.

为了解此预测式之可行性及准确度，本研究针对台北、台中、高雄及高屏地区作混合层高度值的模拟，并将模拟结果与实际观测值、CALMET气象模组及光化学轨迹模式输出结果作比对，结果显示均有0.80以上之高相关性；但与TPAQM计算结果间有明显的高估或低估现象，此为Holzworth method无法考量温度平流效应对混合层发展之影响及探空资料空间解析度不足所致；而在空间分布上，本模式所计算的混合层高度场相较於TPAQM在海陆分布上有较明显的分野，且更能够显示出内陆地区混合层高度的日变化。
