Extreme precipitation (EP) is the main cause of floods, urban waterlogging, debris flow, and soil erosion, which threaten the safety of millions of people life and the development of the economy (

Under the influence of climate change, the Arctic has warmed at least twice the rate of global warming (Ballinger et al., 2020;Rantanen et al., 2022) There has been a corresponding rapid decrease of summer sea ice concentration (SIC) in the seasonal ice area, along with a retreat of Arctic summer sea ice extent, decreasing at a rate of around 13% per decade (Perovich et al., 2020). Consequently, chances have arisen for increased economic and conservation activity in the Arctic, which urges for more precise predictions of Arctic SIC (e.g.
