| Zusammenfassung |
| The radiative impact and climate effects of geoengineering using
sea-spray aerosols have been investigated in the HadGEM2-ES Earth
system model using a fully prognostic treatment of the sea-spray
aerosols and also including their direct radiative effect. Two
different emission patterns were considered, one to maximise
the direct effect in clear skies, the other to maximise the
indirect effects of the sea-spray on low clouds; in both cases
the emissions were limited to 10% of the ocean area. While the direct
effect was found to be significant, the indirect effects on clouds
were much more effective in reducing global mean temperature as
well as having less of an impact on global mean precipitation per
unit temperature reduction.
The impact on the distribution of precipitation was
found to be similar in character, but less in degree, to that
simulated by a previous study using a much simpler treatment of this
geoengineering process. |
