| Summary: | Topography plays an important role in the formation and development of precipitation inmountain areas. In view of the scarcity of meteorological stations in Tianshan Mountains, it isdifficult to deeply understand the spatial distribution pattern and mechanism of precipitation inmountainous areas. Based on the precipitation data of meteorological stations and considered seventopographic factors such as longitude, latitude, elevation, slope, aspect, relief and topographicopenness as principal component analysis indicators, this paper establishes the precipitationestimation model in Tianshan Mountains by the principal-component stepwise regression method. Theresults show that the model can well reflect the precipitation characteristics and seasonalvariations in Tianshan Mountains, with remarkable regression effect, which is applicable tosimulating precipitation in Tianshan Mountains. The simulation results in winter are the best,with the deviation range of -10 mm to 10 mm. The simulation deviations in summer are large, rangingfrom-13 mm to 18 mm. |
