Cloud radiative feedback
Cloud feedback is the coupling between cloudiness and surface air temperature where a surface air temperature change leads to a change in clouds, which could then amplify or diminish the initial temperature perturbation. Cloud feedbacks can affect the magnitude of internally generated climate variability or they can affect the magnitude of climate change resulting from external radiative forcings. WebApr 13, 2024 · The cooling because of the diminished incoming shortwave radiation overwhelms the warming due to the longwave radiation at the ocean surface. This cloud radiative forcing is observed partly over the cold tongue in sea surface temperature (SST) in the South China Sea. Numerical simulations with a 1-dimensional slab ocean model …

Dear Chen, WebDec 16, 2024 · In all cases, radiation feedback creates a high density, neutral, expanding shell, which may trigger succeeding star formation (Hosokawa & Inutsuka 2006). We also find that effect of absorption of re-emitted photons is negligible in almost all clouds. Only in Cloud X3, radiation pressure is slightly enhanced by this process.
