Distribution model and mapping of monthly average temperature with high space resolution in mountainous areas

In this paper, time series of monthly average temperature were adjusted from 8 meteorological temporal stations in Xianju County, Xianju meteorological station was used as one basic meteorological station in Xianju County in Zhejiang Province. The short time series adjusting model of monthly average temperature were established from 8 meteorological temporal stations. The regression model, in which monthly average temperature varied with longitude and altitude, was established by data of longitude, latitude and altitude obtained by using GPS on the spot. Then 1∶10000 scale Digital Elevation Model(DEM) with high spatial resolution was built by using 1:10000 scale Xianju topographic map. The topographic factors of longitude, altitude, slope and aspect etc were derived from DEM. Distribution models of monthly average temperature were established by combining GIS with monthly average temperature from 9 Meteorological stations in Xianju County in Zhejiang Province. Distribution maps of monthly average temperature with high spatial resolution in Xianju county were generated.
