Abstract:: Atmospheric stability was classified according to hourly observation of the 97 meteorological stations in Shaanxi Province from 2006 to 2011, frequency of occurrence of each station four seasons and years of instability, stability class, and neutral stability was calculated, regional maps of the Guanzhong area was drawed using GIS system, the distribution characteristics of the three categories of stability in seasonal and annual frequency was analyzed. Result show that the highest frequency of stable the class and unstable class are in the Qinling hinterland Midwest and Guanzhong Basin Midwest, followed by Weibei Loess Plateau,northern Shaanxi, Fengxian and Taibai county; Hanzhong City and Ankang southwest are lower frequency. The highest frequency of neutral class significantly are in Fengxian and Taibai county which situated in Baoji southwest Qinling Mountain,Hanzhong and Ankang southwest, The least frequency are in Guanzhong Basin Midwest and eastern Weibei. For stable class, winter appear most frequently, followed by autumn, and lowest in summer; For summer appear the highest frequency, followed by spring, lowest in winter; For the neutral class, the highest frequency appear in autumn, followed in summer, winter and spring is minimum. The high-frequency region of unstable class also are the region which have high-frequency of stable class.
