摘要：

The direct climate effect of aerosols has been studied within a regional atmospheric model of the Arctic. The mean springtime effect on the near surface temperature has been estimated and showed to be within +/- 1 K. However, the aerosol effect varies strongly regionally depending on the surface albedo, atmospheric humidity, and cloud condition of the region. The interannual variability of the aerosol effect is very pronounced ( for the near surface temperature in the order of 2 K) and is connected with the strong varying year-specific atmospheric conditions. Due to the high horizontal resolution of the model, it was possible to assess the influence both on the large-scale as well as on the meso-scale atmospheric circulation. Through the aerosol-radiation-circulation feedback, the scattering and absorption of radiation by aerosol cause pressure pattern changes which have the potential to modify Arctic teleconnection patterns like the Barents Sea Oscillation.
