The HadGEM2-AO climate model includes atmospheric GCM, N96 (1.875×1.25) horizontal and 38 vertical levels, the top of the atmosphere is about 38 kilometers, marine GCM horizontal resolution is 1 degree (increased to 1/3 degree at the equator) and 40 vertical levels . Atmospheric GCM levels use the Arakawa C grid, and scalar variables such as temperature and density are staggered with wind and other vector fields. The vertical coordinate is based on the height of the Charney-Phillips grid. In addition, it is a terrain following, non-still water, deep atmosphere formula. Marine GCM is based on the Bryan-Cox code, using the Arakawa B grid horizontally and using the Z coordinate vertically. The model time steps are 30 minutes (atmosphere and land) and 1 hour (ocean), and the coupling occurs at each dynamic time step in the land-atmosphere system. The coupling between the ocean and the atmosphere is a daily time scale.

#### Model Description

English {{currentDetailLanguage}} English

We describe the HadGEM2 family of climate configurations of the Met Office Unified Model, MetUM. The concept of a model “family” comprises a range of specific model configurations incorporating different levels of complexity but with a common physical framework. The HadGEM2 family of configurations includes atmosphere and ocean components, with and without a vertical extension to include a well-resolved stratosphere, and an Earth-System (ES) component which includes dynamic vegetation, ocean biology and atmospheric chemistry. The HadGEM2 physical model includes improvements designed to address specific systematic errors encountered in the previous climate configuration, HadGEM1, namely Northern Hemisphere continental temperature biases and tropical sea surface temperature biases and poor variability. Targeting these biases was crucial in order that the ES configuration could represent important biogeochemical climate feedbacks. Detailed descriptions and evaluations of particular HadGEM2 family members are included in a number of other publications, and the discussion here is limited to a summary of the overall performance using a set of model metrics which compare the way in which the various configurations simulate present-day climate and its variability.
