International audience We report the sensitivity of the Berlin Climate Middle Atmosphere Model (CMAM) to different gravity-wave (GW) parameterisations. We perform five perpetual January experiments: 1) Rayleigh friction (RF) (control), 2) non-orographic GWs, 3) orographic GWs, 4) orographic and non-...
