Trends and Variability of North Pacific Polar Lows
Figure 4
((a), (b)) First two canonical correlation coefficient time series (dashed lines represent the Polar Low occurrence and solid lines represent the MSLP pattern) and ((c), (d)) corresponding canonical correlation patterns between regional time series of Polar Low occurrences per PLS in subregions R1–R12 (△ for positive values, ▽ for negative values) and mean sea level pressure fields in Pa. The first CCA pair ((a) and (c)) shares a correlation coefficient of 0.89. The second CCA pair ((b) and (d)) shares a correlation of 0.72.
