摘要: Cloud-aerosol interactions are considered as one of the largest sources uncertainties in study climate change. Here, another possible cloud-aerosol effect on is proposed. A series Large Eddy Simulations (LES) with bin microphysics reveal a sensitivity total atmospheric water vapor amount to aerosol concentration. Under polluted conditions rain suppressed and atmosphere increases time compared clean precipitating conditions. Theoretical examination this transport from subtropics tropics, hence equatorial Hadley circulation, conducted using an idealized General Circulation Model (GCM). It shown that reduction subtropical results increased advection tropics enhanced circulation. This joins previously proposed mechanisms radiative general
