Passive tracers in a general circulation model of the Southern Ocean [PDF]

open access: yesAnnales Geophysicae, 1999
Passive tracers are used in an off-line version of the United Kingdom Fine Resolution Antarctic Model (FRAM) to highlight features of the circulation and provide information on the inter-ocean exchange of water masses.

Circulation type analysis of regional hydrology: the added value in using CMIP6 over CMIP5 simulations as exemplified from the MPI-ESM-LR model

open access: yesJournal of Water and Climate Change, 2022
This study addresses the applicability of general circulation models (GCMs) in studying the impact of climate change on hydrology. The statistical downscaling of precipitation based on circulation types (CTs) derived from the fuzzy, i.e., more than one ...

Superparameterised cloud effects in the EMAC general circulation model (v2.50) – influences of model configuration [PDF]

open access: yesGeoscientific Model Development, 2020
A new module has been implemented in the fifth generation of the ECMWF/Hamburg (ECHAM5)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) model that simulates cloud-related processes on a much smaller grid.
