Impact of Aerosol on Precipitation and Snow Water Equivalent
Aerosols warm the California mountain tops through aerosol-snow interaction by local dust but cools the lower elevation areas through aerosol-radiation interaction and aerosol-cloud interaction by transported and local anthropogenic aerosols.
Aerosols reduce precipitation and snowpack in California primarily through aerosol-cloud interaction by transported and local anthropogenic aerosols and aerosol-snow interaction by local dust.
Aerosols cause earlier snowmelt at mountain tops through aerosol-snow interaction by local dust, leading to reduced surface runoff after April.
Impact of Aerosol on Inflows
The presence of aerosols results in significant reduction of annual reservoir inflows by 4% - 14% in California.
In the summer, aerosols reduce precipitation, snow water equivalent, and snowmelt which leads to a reduction in inflow by 11%-26%.
