To do so, we must compute a mean 21 19 of speed velocities using velocities around T-point at i,j location and not i-1,j-1 location as it is done in the reference.[[BR]] … … 63 61 }}} 64 62 65 ---- 63 It results in a systematic icethickness decreasing O(-2/4 cm) in winter (March) along the sea-ice edge.[[BR]] 64 Whereas "inside" Arctic area, it increases lightly icethickness O(+1/2 cm) with max. O(+10 cm) in the Hudson bay and off 65 the North Siberian coast.[[BR]] 66 The trend for ice fraction leads is the same, i.e. an decreasing between O(-1/5 %) at the sea-ice limit extent.[[BR]] 67 But it doesn't change radically the icethickness differences with with the SDP3 New run. Patterns are still unchanged in Arctic.[[BR]] 68 So even this bug correction doesn't explain the big differences between REF_CORE and SBC_NEW experiments.[[BR]] 69 70 '''Ice thickness diffs. between REF_CORE SDP6 - REF_CORE SDP5 / Year 10 / Winter March''':[[BR]] 71 [[Image(SDP6_Ref_SDP5_Ref_icethic_March.png, 90%)]] 72 ---- 73 '''Fraction leads diffs. between REF_CORE SDP6 - REF_CORE SDP5 / Year 10 / Winter March''':[[BR]] 74 [[Image(SDP6_Ref_SDP5_Ref_ileadfra_March.png, 90%)]] 75 ---- 76 '''Ice thickness diffs. between SBC_NEW SDP3 - REF_CORE SDP6 / Year 10 / Winter March''':[[BR]] 77 [[Image(SDP3_NEw_SDP6_Ref_icethic_March.png, 90%)]] 78 ---- 79 66 80 == '''FULL_SDP5''': == 67 81 '''* FULL_SDP5''':[[BR]] … … 93 107 ---- 94 108 95 ----96 109 == '''FULL_SDP4''': == 97 110 '''* FULL_SDP4''':[[BR]] … … 123 136 ---- 124 137 125 ----126 138 == '''FULL_SDP3''': == 127 139 '''* FULL_SDP3''':[[BR]]
