《Satellite-observed trends in the Arctic sea ice concentration for the period 1979–2016》
The results refl ected by table 5 are based on ice growth model in ice-covered areas and show that sea ice estimated decrease rates are in tune with the observed results.All subregions of the Arctic have varying degrees of ablation due to air temperature increase during the period 1979–2016，especially the Kara Sea and Barents Sea.In the Kara Sea，0.132degree warmer air gives 0.826 W/m 2 extra sensible heat fl ux on sea ice，reducing 0.021 m sea ice in a year，and 0.222 degree SAT rise transfers 1.646 W/m 2extra sensible heat fl ux into sea ice，reducing 0.043 m sea ice growth in one autumn.Besides，the sea ice rapidest decreasing time in the entire Arctic sea icecovered areas is autumn in which 0.165 degree warmer of SAT reduces 1.351 W/m 2 sensible heat into the air，retreats 0.031 m sea ice.All of these data above imply that the eff ects of climate parameters on sea ice are very signifi cant.The estimate caculation of ice growth reduction due to climate parameters neglected the infl uences of latent heat fl ux，solar radiation fl ux，long-wave fl ux of cloud，long-wave fl ux of ice，etc.Besides，T s and h Iwe used in formulas are estimates，which would lead to some errors for the result，while it can also exhibit the eff ects of climate parameters on sea ice to some extent.In fact，the Arctic Ocean is not covered with ice throughout the year，and there will be a large area of open water in summer.Thus，we calculated the ice growth based on the ice growth model in ice-free areas.Compared with the ice growth model in ice-covered areas（Eq.4），this formula is without thermal conductivity，and the results of the ice growth reductions are shown in Table 6.Therefore，the reasonable estimated value should be between the two extreme cases（no ice case and ice-covered case）.
