Regional photochemical reaction is weak over this area , to a great extent , the atmospheric background condition influences to the variation of surface o3 , tthe variation of vertical wind speed is significant to surface o3 , from seasonal distribution of vertical wind , it appears upward air current in winter , spring and autumn , repectively , while it is mainly downward in summer , it is favorable to the o3 transport from stratosphere layer . at walilguan , the variation of humidity impacts a little on surface o3 , the relationship between surface o3 and wind speed is relatively complicated , by correlation statistic analyze , it is sure that the wind speed is not one of the important factor
( 2 )瓦里关地区局地光化学反应较弱，地面o _ 3在很大程度上受大气背景状况的影响； ( 3 )垂直风变化对地面o3日变化影响较大，从垂直风季节分布看，春、秋、冬三个季节为上升气流，而夏季下沉气流则很旺盛，这种分布有利于平流层o _ 3向下的输送； ( 5 )湿度对地面o _ 3贡献并不明显； ( 6 )各季节水平风速与地面o _ 3之间的关系较为复杂，不同季节相关分析表明，水平风速并不是影响地面o _ 3变化的主要因子之一。
