• 摘要：本文采用北京气象台和320米塔多年来测得的风和温度资料,统计分析了各稳定度类的边界层厚度(BLD)特征,得到北京地区稳定度类频率、平衡条件下的BLD、BLD的诊断模式及夜间BLD的预报模式,为中远距离的输送扩散、污染模式及边界层结构的研究提供依据.

• Abstract：By using the observed wind and temperature data of Beijing observatory and 320m-tower for several years, boundary layer depth (BLD) characteristics under different stability categories are statistically analysed. Frequency of stability categories in the Beijing area, BLD under equilibrium conditions, the diagnostic models of BLD and forecasting models of nocturnal BLD, are obtained. Results are enough to study on pollution models in mesomacroscale range and boundary layer structure.
