Unravelling the temperature–precipitation relationship in Ny-Ålesund—a high-arctic maritime climate (opens in new tab)

Precipitation is a key component of the Arctic hydrological cycle, yet its variability and extremes remain poorly understood and constrained due to sparse long-term observations. Arctic amplification is rapidly transforming precipitation regimes, with major implications for the high-latitude hydrology and the cryosphere. Here we examine the temperature–precipitation (T–P) relationship at Ny-Ålesund, Svalbard, using Clausius–Clapeyron (C–C) scaling applied to long-term observations (1974–2023)...
