| Zusammenfassung |
| Clouds and the atmospheric state play fundamental roles in the cryospheric mass budget of
the Greenland Ice Sheet both as a source, via precipitation, and a potential sink, via
modulation of the surface energy budget. In this study we use regional climate model
simulations to identify the differing impact of local and remote moisture sources on cloud
formation and the surface energy budget at Summit, Greenland. A focus of these studies is to
investigate air mass sources that cause both mid-tropospheric ice clouds and mixed-phase
stratocumulus to form and the interaction between these different cloud types. For example,
how the modification of air masses aloft may prevent stratocumulus from forming by
producing ice clouds through homogeneous freezing that precipitate ice into the boundary
layer. Sensitivity studies will be presented and discussed that explore how perturbations to
local and remote moisture sources, due to changes in sea surface temperatures and
sea ice extent, impact cloud formation and the surface energy budget at Summit. |
