The Atmospheric Response to Realistic Reduced Summer Arctic Sea Ice Anomalies - Arctic Sea Ice Decline: Observations, Projections, Mechanisms, and Implications - page 103

Plate 10. (a) Observed SLP anomalies in August 1995 in hPa. The mean climatology is based on the years 1968-1996,
and the CI is 2 hPa. (b) Observed 500-hPa geopotential height composites based on reduced ice in the Kara Sea region.
The 500-hPa height is in meters. Shading indicates statistical significance at the 95% or greater level based on a pooled
variance t statistic. The years used in this composite are 1979, 1984, 1985, 1994, 1995, 1997, and 2000.
