气溶胶粒子对城市夜间边界层温度影响的模式研究

MODEL STUDY OF EFFECTS OF AEROSOLS ON URBAN NIOHTTIME BOUNDARY LAYER TEMPERATURE

摘要:

用一维非定常模式模拟大气气溶胶粒子对城市夜间边不层大气温度场的影响。结果表明:气溶胶粒子对近地层大气起增温作用,对150m以上大气起降温作用,并削弱近地逆温层的强度。

Abstract:

An one-dimensional unsteady model is developed for the effects of aerosols uponurban nighttime boundary layer temperature. Results show that these particles are responsible for near-surface layer temperature increase,as opposed to the condition at 150m aboveground.
