Abstract. The Arctic sea ice extent throughout the melt season is closely associated
with initial sea ice state in winter and spring. Sea ice leads are important
sites of energy fluxes in the Arctic Ocean, which may play an important role
in the evolution of Arctic sea ice. In this study, we examine the potential
of sea ice leads as a predictor for summer Arctic sea ice extent forecast
using a recently developed daily sea ice lead product retrieved from the
Moderate-Resolution Imaging Spectroradiometer (MODIS). Our results show that
July pan-Arctic sea ice extent can be predicted from the area of sea ice
leads integrated from midwinter to late spring, with a prediction error of
0.28 million km2 that is smaller than the standard deviation of the
observed interannual variability. However, the predictive skills for August
and September pan-Arctic sea ice extent are very low. When the area of sea
ice leads integrated in the Atlantic and central and west Siberian sector of
the Arctic is used, it has a significantly strong relationship (high
predictability) with both July and August sea ice extent in the Atlantic and
central and west Siberian sector of the Arctic. Thus, the realistic
representation of sea ice leads (e.g., the areal coverage) in numerical
prediction systems might improve the skill of forecast in the Arctic region.
