Due to the existence of seasonal or perennial sea ice cover, the determination of the Arctic sea surface is more difficult than that of mid-low latitudinal oceans. Focusing on the sea surface height in the ice-covered region, this paper constructs a

The rare extreme flooding event in Henan Province, China, during July 2021 (referred to as the “21.7” flooding event) was attributable to persistent heavy rainfall boosted by an enhanced moist southeasterly flow and substantial moisture convergen
