We used NCAR/NCEPT anew analyze data and the method of bilinearity insert to fix on profile distribution of several physical field in the air on observation point and the stream field of 700hPa. We primary discussed the possible mechanism to influence aerosol size distribution.The atmospheric condition of 1000hPa~700hPa level had great influence on aerosol size distribution, and influence on coarse particle mainly below 850hPa level. The horizontal wind velocity of 925hPa level is a primary gene which contributed to coarse particles in the air. Vorticity profile especially below 700hPa level is a key gene to influence diffuse and convergence of local aerosol. The air vertical motion velocity greatly influenced aggregation and remove of aerosol particles. The vertical distribution of air temperature mainly influenced vertical transportation of aerosol.
利用NCAR/NCEP逐日再分析资料,通过双线性插值方法,确定观测点上大气中几个物理量的廓线分布;及700hPa的流场,初步探讨了影响大气中气溶胶粒子谱分布的可能机制: 1000hPa~700hPa的大气状况对气溶胶粒子谱分布影响显著,对粗粒子气溶胶的影响显著的主要集中在850hPa以下;925hPa的水平风速是影响大气中粗粒子气溶胶的一个主要因子;涡度廓线(尤其是700hPa左右及以下的涡度廓线)是影响局地气溶胶的扩散的一个关键因子;大气的垂直运动速度对气溶胶的聚合及移出影响较大;大气温度的垂直分布主要影响气溶胶垂直输送。
