Slope of quantile regressions between anomalies of EKE and temperature in winter.
Regression slopes are shown for the 90th-percentile (a), 50th-percentile (b) and 10th-percentile (c). Stippling indicates significance at the 5%-level and grey contour lines denote EKE climatology in winter. Land regions higher than 1 km have been masked. All maps are created using the open source software R.
