Record Label : volc-pinatubo-surf
Record Title : Pinatubo experiment with partial radiative forcing, solar radiation scattering only
Record identifier : f16f93b0-dd9e-11e6-b89b-ac72891c3257
Description : 1991 Pinatubo forcing is expressed with a prescribed perturbation to the shortwave flux to mimic the attenuation of solar radiation by volcanic aerosols and therefore the cooling of the surface. Maintain the same constant boundary forcing as the pre-industrial control integration, except for the volcanic forcing. Requires special diagnostics of parameterised and resolved wave forcings, radiative and latent heating rates. The experiment will not account for the actual climate conditions when the real event occured (e.g., presence and strength of additional forcing factors). Instead, the experiment is designed to span very different initial climate states to systematically assess uncertainties in the post-eruption behaviour that are related to background climate conditions. Sampling of an eastern phase of the Quasi-Biennial Oscillation (QBO), as observed after the 1991 Pinatubo eruption is preferred for those models that spontaneously generate such mode of stratospheric variability. Run at least 25 ensemble members for 3 years.
