Trends and Variability of North Pacific Polar Lows

Figure 6

Associated correlation patterns between time series of geopotential height over 62 PLSs and time coefficient of the Polar Low occurrence from the first two CCA patterns (1st CCA pair, left column, 2nd right column). From top to bottom, 100, 300, 500, 700, 850, and 1000 hPa. All variables are averaged across a Polar Low season, that is, from October to April.
