Following moist intrusions into the Arctic using SHEBA observations in a Lagrangian perspective
Abstract Warm and moist air masses are transported into the Arctic from lower latitudes throughout the year. Especially in winter, such moist intrusions (MIs) can trigger cloud formation and surface warming. While a typical cloudy state of the Arctic winter boundary layer has been linked to the adve...
