Based on two processes of the severe sandstorm and the strong wind with dust, this study on spatial distribution characteristics of temperature advection aims at the atmospheric stratification in Inner Mongolia. The results show that during the sandstorm and high wind processes cold advections are stronger than normal, but have different vertical distribution characteristics. The strong cold advections have significant impacts on atmospheric stratification stabilities, vertical temperature profiles and vertical movements. The center of the strong cold advection exists in the higher layer from 700 hPa to 600 hPa, overlapping the weak cold advection in the near surface layer, forming temperature advection differences between higher and lower levels, and increasing vertical temperature lapse rate, which is favorable for the formation of the deep unstable stratification in the sandstorm processes. After the unstable energy is released in the process of the dry convective windstorm formation, the atmosphere stratification tends to become neutral or mixed layer, where the energy exchange is in an equilibrium state. In high wind process, strong cold advection center is located in the lower level of 850 hPa, which is not conducive to the formation of unstable stratification. The mixing layer height is consistent with the sandstorm height, whose location is about 150 hPa higher than the strong cold advection center, when the strong cold advection center (-45×10-3 ℃·s-1) is in the 700-600 hPa level and the thichness of the mixing layer gets to 500 hPa or higher. This sandstorm weather process with such intensity can influence the south of the Yangtze River and the coastal areas of China.
