[[BR]] [[PageOutline]] = '''PHC_9 run''' = This run is based on the PHC_8 one except on the way the wind stress and module are managed.[[BR]] Wind stress seems to be too low (in PHC_8) in high latitudes compared to what we have in using standard [[BR]] CLIO data this component is capital for the water mass formation & penetration in these areas so it must be increased.[[BR]] So we do the following test:[[BR]] - compute off-line the daily climatology of the fields (wndm.u)clim and (wndm.v)clim using 6hourly wind velocities.[[BR]] - we use the wind module computed with the 6hourly wind velocities which is much more energetics than the one computed using climatological velocities.[[BR]] Note that we don't substract the ocean/sea-ice velocities when computing the wind module since this last is now read. ---- === '''DFS4''' wind module, wind stress & wind components === Annual mean wind stress ''like'' differences: {{{ * STRONG - SMOOTH * (||wndm||.U)clim - ||wndm||clim.Uclim * (||wndm||.V)clim - ||wndm||clim.Vclim }}} [[Image(DFS4_Strong_Smooth_Uu_Uv_1y.png, 60%)]] Seasonal variability wind stress differences: animation (gif)[[BR]] [[Image(DFS4_anim_Strong_Smooth_U.u_1dclim.gif, 60%)]] [[Image(DFS4_anim_Strong_Smooth_U.v_1dclim.gif, 60%)]] Annual mean wind module variance differences: {{{ * STRONG - SMOOTH * SQRT[ ||wndm||clim^2 - (Uclim^2 + Vclim^2) ] }}} [[Image(DFS4_Strong_Smooth_wndm_variance_1991-2000.png, 60%)]] Annual mean wind velocity U: [[BR]] [[Image(DFS4_u10_1991-2000_ymean.png, 60%)]] Annual mean wind velocity V: [[BR]] [[Image(DFS4_v10_1991-2000_ymean.png, 60%)]] ---- === '''Zonal mean tauX wind stress''' with PHC_8, CLIO and initial calculation: === [[Image(Zonal_tauX_PHC9_PHC8_CLIO_CORE_INIT.png, 60%)]] === '''tauX wind stress''' differences with PHC_8: === [[Image(PHC9_PHC8_tauX_diff_y10.png, 60%)]] === '''wind module''' differences with PHC_8: === [[Image(PHC9_PHC8_wndm_diff_y10.png, 60%)]] === '''SST''' differences with Reynolds and PHC_8: === [[Image(PHC9_NewReynolds_PHC8_SST_y10.png, 60%)]] ---- === '''Temperature''' differences at z=105 m with Levitus and PHC_8: === [[Image(PHC9_Levitus_PHC8_T_z105_10.png, 60%)]] ---- === '''SSS''' differences with Levitus and PHC_8: === [[Image(PHC9_Levitus_PHC8_SSS_y10.png, 60%)]] ---- === '''Temperature''' differences in '''zonal average''' with Levitus and PHC_8: === [[Image(Zonal_PHC9_Levitus_PHC8_T_y10.png, 60%)]] ---- === '''Salinity''' differences in '''zonal average''' with Levitus and PHC_8: === [[Image(Zonal_PHC9_Levitus_PHC8_S_y10.png, 60%)]] ---- === '''Equatorial''' differences with Levitus and PHC_8 of '''zonal velocity U''': === [[Image(Eq_PHC9_PHC8_U_y10.png, 60%)]] ---- === '''Equatorial''' differences with Levitus and PHC_8 of '''temperature''': === [[Image(Eq_PHC9_PHC8_T_y10.png, 60%)]] ---- === '''Equatorial''' differences with Levitus and PHC_8 of '''salinity''': === [[Image(Eq_PHC9_PHC8_S_y10.png, 60%)]] ---- === '''Pacific''' '''equatorial''' differences with Levitus and PHC_8 of '''temperature''': === [[Image(Eq_Pcf_PHC9_PHC8_T_10.png, 60%)]] ---- === '''Qnet''' differences with PHC_8 : === [[Image(PHC9_PHC8_Qnet_y10.png, 60%)]] === '''Erp & Mxl''' fields: === [[Image(PHC9_Erp_Mxl_y10.png, 60%)]]
