Affected by the mountain underlying surface, temperature distribution sometimes appears anomalies, i.e., terrain inversion (the temperature on the mountain top is greater than that at the foot of the mountain) in the Jiuhua Mountain during the period of temperature increase. Through the comparison of temperatures at different heights in the mountains and the diurnal variation characteristics of analysis， it is concluded that： terrain inversion usually appears in the temperature increase period in the mountains, and the anomalous characteristics in the vertical distribution of daily minimum temperature are most obvious (compared with daily average temperature and maximum temperature)； the terrain inversion of minimum temperature has obvious seasonal characteristics；the terrain inversion of the daily minimum temperature has good indicative significance to weather changes. After the disappearing of terrain inversion in the warming period, there will certainly is a cooling, in which rainfall and complex weather situation will happen. There is a fairly good relationship between the time and amplitude of terrain inversion and the subsequent cooling duration and cooling amplitude. Therefore, to analyze the spatial and temporal variation of temperature in the complicated mountainous terrain is helpful for temperature prediction.
