考虑湿度影响的城市气溶胶粒子白天温度效应

Influence of Urban Aerosols with Humidity Effect on Temperature during Daytime

利用一维晴空大气边界层模式， 在详细计算气溶胶短波辐射增温率的基础上， 研究了环境相对湿度和气溶胶粒子浓度对边界层气溶胶白天温度效应的影响。结果表明， 相对湿度的增加与气溶胶粒子浓度的增加在边界层中具有一致的温度效应， 均使边界层中上层增温， 近地层降温， 从而稳定度增大。

Based on detailed calculations of aerosol heating rates, the effects of relative humidity and aerosol concentration on temperature field in diurnal boundary layer are studied by use of an unsteady one-dimensional numerical model Results show that increases of relative humidity and aerosol loading have the same temperature effects in PBL with cooling near the surface and warming aloft, thereby increasing the boundary layer stability
