| 摘 要： | 分析了玉米开花期间的边界层温湿风等特征量,结果表明,温度和湿度一般与高度呈相反的变化趋势,并且湿度廓线与理查森数的变化有较好的对应性,能够粗略地反映湍流的稳定度;在200～300 m高空,风速一直很大,可以推测在此高度存在一个较强的大气扩散区;观测期间,温度在18.5～32.0℃时,风速在0.8～5.8 m/s,风向稳定且以偏北风为主,十分有利于玉米授粉。

| Abstract: | The characteristics of boundary layer during the maize lowering were studied.Results suggested that temperature and humidity had opposite changing trend with height,and there were a good number of correspondences between humidity profiles and Richardson profiles which roughly reflected the turbulence of stability.In the height of 200-300 m,wind speed was fast,and there was an atmospheric diffusion zone.During the observation period,temperature was 18.5-32 ℃,wind speed changed from 0.8 to 5.8 m/s.Wind direction was steady and mainly was northerly wind,which was conductive to the pollination of corn. |
