Regional differentiation based on permutation entropy and its geographical explanation

The study area, located in the southwest of Yunnan Province, has a distinct regional difference in both topography and climate system. Western region belongs to the Southwestern Yunnan mountainous area with varied landforms while eastern region is a part of Eastern Yunnan Plateau whose terrain is rather flat relatively. And different regions are influenced by different climates, which have resulted from the multiplicity of monsoon systems and the significance of great topographic effects. By a complexity parameter--permutation entropy for time series from 1971 to 2000 based on comparison of neighboring values, the tolerance to the complexity of climate systematic is simple and effectual. And there is a good geographical explanation of both atmospheric circulation and localized topography to
