Aims and Description

The Aqua-Planet Experiment Project (APE) compares idealised climates simulated by atmospheric global circulation models (AGCMs) which are being used and developed for numerical weather prediction and climate research.

Each AGCM is used to simulate the climate on a water covered world using several idealised distributions of sea surface temperature. This simplified environment will focus attention on the distribution and variability of convection in the tropics and of the storm-tracks in mid-latitudes.

The experiment aims to provide a benchmark of current model behaviour and, more importantly, to stimulate research to understand the causes of inter-model differences, arising from different subgrid-scale parameterization suites, different dynamical cores, and different methods of coupling the two.
