Variability in Weather Generator Simulations
No full textThis technical note illustrates and assesses the variability introduced by the Weather Generator relative to that from the change factors within the UKCP09 probabilistic projections
Report from the Review of the Methodology used for the UKCP climate change projections
No full textThe Review Group would like to emphasise that the work performed by the Met Office Hadley Centre (MOHC) and by other Weather Generator and Marine Report contributors
was at a very high level. The methodologies used are credible, though sometimes very complex. UKCP represents a large step beyond UKCIP02
Climate and Forecast (CF) Metadata Conventions: A Community Driven Metadata Standard
No full textThis poster provides a brief introduction to the purpose and scope of CF Metadata. It describes some of the main features of the metadata conventions and explains the process by which the conventions evolve
The Role of Atmosphere Feedbacks During ENSO in the CMIP3 Models
No full textSeveral studies using ocean-atmosphere GCMs suggest that the atmospheric component plays a dominant role in the modelled ENSO. To help elucidate these findings, the two main atmosphere feedbacks relevant to ENSO, the Bjerknes pos-
itive feedback (μ) and the heat flux negative feedback (α), are here analysed in 12 coupled GCMs.
We find that the models generally underestimate both feedbacks, leading to an error compensation. The strength of α is inversely related to the ENSO amplitude in the models and the latent heat and shortwave flux components of this feedback dominate. Furthermore, the shortwave component could help explain the model diversity in both overall α and ENSO amplitude
