Inter-model diversity in jet stream changes and its relation to Arctic climate in CMIP5
We examined how coupled general circulation models (CGCMs) simulate changes in the jet stream differently under greenhouse warming, and how this intermodel diversity is related to the simulated Arctic climate changes by analyzing the simulation of the Coupled Model Intercomparison Project Phase 5.
