Fig. 4: Atmospheric cross sections of the July 2014 atmospheric river (AR)-foehn event over the 79°N Glacier region of northeast (NE) Greenland.
From: Increasing extreme melt in northeast Greenland linked to foehn winds and atmospheric rivers
Cross sections are derived from Polar Weather Research and Forecasting (Polar WRF) model simulations and cover the transect shown by the black dashed line in Fig. 1b. The colored contours represent air temperature (T), black lines show the potential temperature (θ), and green contours are the specific humidity (q). Relative humidity (RH) values above 70% are depicted by dots. The vertical black line highlights the location of the floating tongue of 79°N Glacier. The panels are during different time periods throughout the case study from (a) 18 July 2014 1200 UTC (AR landfall in NW Greenland); (b) 19 July 2014 1200 UTC (AR-initiated foehn development); (c) 20 July 2014 1200 UTC (Peak AR-foehn impact); and (d) 22 July 2014 1200 UTC (AR-foehn cessation).
