Fig. 5: Influence of atmospheric rivers (ARs) and foehn conditions on northeast (NE) Greenland melt.
From: Increasing extreme melt in northeast Greenland linked to foehn winds and atmospheric rivers
a Climatological mean hourly melt in NE Greenland during summer (JJA). b Percentage of melt coincident with foehn conditions during the 0–48 h period after 90th percentile ARs (AR90) in northwest (NW) Greenland. c Temporal evolution of foehn-driven melt in northeast (NE) Greenland in 500 m elevation bands during the −48 to +48 h period surrounding NW Greenland ARs. Lines are mean values and shading displays the standard error of the mean. (d) Map of percentage of extreme (>99th percentile) melt coincident with foehn conditions. Melt data are from the polar Regional Atmospheric Climate Model version 2.3p2 (RACMO2) and ARs are identified from the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) reanalysis using the Mattingly algorithm.
