Analysis of Arctic Sea Ice Anomalies in a Coupled Model Control Simulation - Arctic Sea Ice Decline: Observations, Projections, Mechanisms, and Implications - page 199

Figure 9. Time series from ccSm3 control simulation for model years 545 to 580 indicating (a) September Northern
Hemisphere sea ice extent expressed as an anomaly of the averaging period 250-599 in 10 6 km 2 , (b) September Northern
Hemisphere sea ice volume anomaly in km 3 , (c) Fram Strait southward ice export anomaly for November through April
in km 3 month -1 , (d) January through December sea ice melt anomaly in cm d -1 , and (e) the first principal component of
the monthly Northern Hemisphere sea level pressure anomaly as computed over the period 250-599.
