Abstract:

North-Atlantic Cold-air outbreaks are weather events characterised by extensive fluxes of latent heat to theatmosphere. Understanding the water budget of these weather events is important for the weather impact indownstream coastal areas. We use here observations of the stable isotopic composition of water vapour andprecipitation, expressed by the quantities dD, d18O, d17O and the secondary parameters d-excess and 17O-excess,to extract information about the origin and condensation history of water vapour evaporating during a period ofcold-air outbreaks north of Iceland
