The effects of atmospheric sulfur on the radiative properties of convective clouds: a limited area modeling study
| Andronache, C., L. J. Donner, V. Ramaswamy, C. J. Seman, and R. S. Hemler, 1998: The effects of atmospheric sulfur on the radiative properties of convective clouds: a limited area modeling study. Geophysical Research Letters, 25(9), 1423-1426 |
| Abstract: Convective clouds in tropical areas can be sensitive to the atmospheric sulfate loading, particularly during enhanced sulfate episodes. This assertion is supported by simulations with a high resolution limited area non-hydrostatic model (LAN) employing a detailed sulfate-cloud microphysics scheme, applied to estimate the effects of sulfate on convective clouds in a case study from the Tropical Ocean Global Atmosphere Coupled Ocean Atmosphere Response Experiment (TOGA COARE). Results show that a change in sulfate loading for scenarios using the minimum to the maximum observed values produces a change in the average net flux of shortwave radiation above clouds. This time-average change was estimated between -1.1 and -0.3 Wm -2 over the integration domain. |
