山区实测资料短缺对研究山地逆温带来不便,利用复杂地形下月平均气温分布式模型模拟的气温结果,对天山、哀牢山、武夷山山区逆温的高度、厚度、强度进行了研究,描述了逆温的时空分布规律,并对其成因进行了简要分析。研究结果表明各山都存在多层逆温,相比山体上部来讲山脚逆温出现频率高,强度较大,厚度达到400 m。不同坡向逆温出现的海拔高度、厚度、强度不同,但不同年份的总体走势变化不大。经过对比,证明利用复杂地形下月平均气温分布式模型得出的逆温结果与前人成果具有一致性,能较好地反映出我国不同气候区域山地区逆温随坡向的分布和季节变化特征,对局地小气候的特征规律也能够较好的表达。
山區實測資料短缺對研究山地逆溫帶來不便,利用複雜地形下月平均氣溫分佈式模型模擬的氣溫結果,對天山、哀牢山、武夷山山區逆溫的高度、厚度、彊度進行瞭研究,描述瞭逆溫的時空分佈規律,併對其成因進行瞭簡要分析。研究結果錶明各山都存在多層逆溫,相比山體上部來講山腳逆溫齣現頻率高,彊度較大,厚度達到400 m。不同坡嚮逆溫齣現的海拔高度、厚度、彊度不同,但不同年份的總體走勢變化不大。經過對比,證明利用複雜地形下月平均氣溫分佈式模型得齣的逆溫結果與前人成果具有一緻性,能較好地反映齣我國不同氣候區域山地區逆溫隨坡嚮的分佈和季節變化特徵,對跼地小氣候的特徵規律也能夠較好的錶達。

The shortage of observation data in mountain areas brings great inconvenience for studying tempera-ture inversion.The results of distributed simulation of monthly mean temperature was used under complex terrains to study the altitude, thickness and strength of temperature inversion layer of Tianshan Mountain, Ailao Mountain and Wuyi Mountain, describe the temporal and spatial distribution of temperature inversion, and carry on the brief analysis of its causes.The results prove that all mountains have multiple temperature inversion layers.Compared with the upper part of mountain, the temperature inversion layer appears more frequently and intensely on the foot of the mountain, and has the thickness of 400 meters.The altitude, thickness and strength of temperature inversion layer which appear in one aspect are different from another.However, the overall trend has little change in different years.By contrast, it prove that the results of temperature inversion obtained from the monthly mean temperature model are consistent with previous ones.They can better reflect the characteristics of temperature inversion in mountain areas in the different climatic zones in our country distributing with aspects and changing with seasons, and better express the characteristics and rules of local microclimate as well.At the same time, they can contribute to the effective use of temperature inversion resource in mountain area.
