Adjusting Methods for Daily Minimum Temperature Series in High Altitude Mountainous Areas of Western Guangxi
To solve the problem of sparsely distributed meteorological stations and the difficulty in climate studies of high altitude mountainous area, in this paper, the daily minimum temperature of January, February and December were collected from 6 automatic meteorological stations in Hechi mountainous area, of which the altitude was above 800 m, and their nearby meteorological stations, which were high relative with automatic stations, were taken as corresponding basic stations, then, the daily minimum temperature were adjusted by the method of one-variety regression and difference value. Lastly, comparison analysis was made from the viewpoint of statistics and error correction. The results indicated that there is no remarkable difference between two methods. However, because of the short duration of single time series of meteorological data in automatic station, instantaneous characteristic of minimum temperature and its complicated factors, the adjusting errors are relative larger.
