查询词典 aerosol

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.
