    "abstract": "We use direct and stochastic numerical simulations of the magnetohydrodynamic\nequations to explore the influence of turbulence on the dynamo threshold. In\nthe spirit of the Kraichnan-Kazantsev model, we model the turbulence by a\nnoise, with given amplitude, injection scale and correlation time. The addition\nof a stochastic noise to the mean velocity significantly alters the dynamo\nthreshold. When the noise is at small (resp. large) scale, the dynamo threshold\nis decreased (resp. increased). For a large scale noise, a finite correlation\ntime reinforces this effect.",
