Online climate change projections report Annex 3
Mat Collins, Simon Brown, Tim Hinton, and Tom Howard, Met Office Hadley Centre
In this annex we discuss some generic aspects of climate modelling, including strengths and weaknesses of climate models. These are illustrated by discussion of some of the recent hot topics in modelling, such as the ability of models to simulate modes of climate variability and phenomena such as atmospheric blocking (periods when high pressure dominates the weather and how they might impact the signal of climate change). While in no way comprehensive, it should give a flavour of the type of research which is ongoing in improving our ability to model, understand and predict climate change.
