Preceding winter Okhotsk Sea ice as a precursor to the following winter extreme precipitation in South China
Abstract The winter extreme precipitation over South China (SC) experiences a large year‐to‐year variability, causing uncertainty in its prediction. Here, we find that the boreal winter sea ice concentration (SIC) in the Okhotsk Sea can serve as a precursor to the following winter's extreme pre...
